Opis:
The Polish Universal Neonatal Hearing Screening Program (PUNHSP) has been carried out in Poland for 14 years. The main aim of this Program is to organize hearing screening tests and to gather the Informations about risk factors of hearing loss in almost all newborns in Poland. It consists of 496 centers at 3 referral levels. A total of 5 458 114 children had been registered in the Central Database (CDB) of PUNHSP by the 22nd of August 2017. Bilateral sensorineural hearing loss was the most frequently appearing hearing impairment in children. It was diagnosed in 260 cases in 2016. This report presents the most important results and conclusions concerning the running of the PUNHSP in 2016.

Opis:
The aim of this study was to evaluate the hearing status of call centre operators in relation to their noise exposure. Conventional pure-tone audiometry and extended high-frequency audiometry were performed in 49 workers, aged 22-47 years (mean ± SD: 32.0 ± 6.0 years), working in call centre from 1.0 to 16.5 years (mean ± SD: 4.7 ± 2.9 years). Questionnaire inquiry aimed at collecting personal data, the information on communication headset usage habits, self-assessment of hearing ability and identification of risk factors for noise-induced hearing loss were also carried out. Sound pressure levels generated by the communication headset were determined using the artificial ear technique specified in CSA Z107.56-13 (2013) standard. The background noise prevailing in offices was also measured according to PN-N-01307 (1994) and PN-EN ISO 9612 (2011). Personal daily noise exposure levels in call centre operators varied from 66 to 86 dB (10-90th percentile). About half of the study subjects had normal hearing in the standard frequencies (from 250 to 8000 Hz) in both ears, while only 27.1% in the extended high-frequencies (9-16 kHz). Moreover, both high-frequency and speech-frequency hearing losses were observed in less than 10% of audiograms, while the extended high-frequency threshold shift was noted in 37.1% of analysed ears. The hearing threshold levels of call centre operators in the frequency of 0.25-11.2 kHz were higher (worse) than the expected median values for equivalent (due to age and gender) highly screened population specified in ISO 7029 (2017). Furthermore, they were also higher than predicted for 500-4000 Hz according to ISO 1999 (2013) based on the results of noise exposure evaluation.

Opis:
Background. A stapedectomy or stapedotomy is known as the best treatment option for patients with otosclerosis. Otosclerosis is a primary disease of the bony labyrinth capsule, which is characterized by one or more localized foci, where bone deposition occurs repeatedly. The best and most effective treatment option is a stapedectomy or stapedotomy. Objectives. The present study evaluated the short-term hearing results in patients with otosclerosis after primary stapes surgery. Material and methods. In this retrospective study, the short-term hearing results of all patients with otosclerosis after a primary stapedotomy admitted to the Ahvaz Emam hospital from 2007 to 2017 was evaluated. Improvement in hearing was evaluated according to the pre- and post-audiometry results. Air Conduction (AC), Bone Conduction (BC) and Air-Bone Gap (ABG) thresholds were recorded at 500, 1 000, 2 000 and 4 000 Hz. SPSS software (Version 22.0) was used for statistical analysis. Results. Of the 413 cases, 231 (55.93%) and 182 (44.07%) were females and males, respectively. The mean age of patients was 39.06 ± 11.29 years. The disease in 131 (31.72%) was bilateral. The mean ABG in 341 patients (82.63%) ≤ 10 dB and in 52 patients (12.47%) was 10–20 dB. Conclusions. The results of the study showed that a primary stapedotomy is a successful and effective way to improve short-term hearing results in adults with otosclerosis.

Introduction: Evidence regarding the effect of speechreading is lacking in age-related hearing loss (presbycusis). Thus, in individuals with presbycusis, this study determined whether speechreading would improve word intelligibility. Moreover, the study investigated the effect of speechreading on word intelligibility depending on hearing impairment severity. Materials and methods: This analytical, cross-sectional study involved two groups of individuals aged > 65 years that were enrolled by convenience sampling: 29 individuals with bilateral sensorineural hearing loss compatible with presbycusis (n=58 ears; mean age, 74.1±9.4 years) and 10 controls with at-most-mild hearing loss (n=58 ears; mean age, 73.8±8.5 years). All participants underwent a comprehensive medical and audiological evaluation, which included speech audiometry with and without observation of the audiologist’s face, i.e. speechreading. Within each group, the effect of speechreading was determined as a change in the speech reception threshold. For all statistical analyses, p < 0.05 was considered significant. Results: Both in individuals with presbycusis and controls, speechreading significantly improved speech discrimination (p<.001<.05); however, compared to controls, this effect of speechreading on speech discrimination was more pronounced in individuals with presbycusis (p<.001). Discussion: Individuals with presbycusis or hearing impairment displayed improved spoken-word intelligibility when spoken-word recognition was coupled with speechreading. Thus, speechreading may serve as a “third ear”.

Objective: In this study, our aim was to investigate whether Monocyte/HDL ratio is a marker of the prognosis of the idiopathic sudden hearing loss (ISHL). Study design: Retrospective, case-control clinical trial. Materials and Methods: 45 patients, who were diagnosed with idiopathic sudden hearing loss and were treated with the same therapy regime and 47 healthy volunteers, who applied to the hospital for routine controls and had audiological and laboratory examination between March 2014 and December 2015, were included in the study. Monocyte/HDL ratios of the patients in the study and control groups were calculated from the results of the blood counts and biochemical analysis. Additionally, the study group was divided into two sub-groups regarding their responses (responders and non-responders) to the treatment determined by the audiological examination, which was carried out after 3 months according to the Siegel criteria. The Monocyte/HDL ratios between the groups were statistically evaluated. Results: There was no statistically significant difference between the MHRs of the study and control groups (p=0.574). However, the MHR was significantly higher in the non-responders’ group compared with the responders’ group, although they were treated with the same therapy regimen (p=0.005). Conclusion: There was no difference in MHRs between study and control groups. However, as MHR was higher in the patients with good prognosis compared with the patients with bad prognosis, we believe that regarding the ISHL, MHR is not a predictive value but might have prognostic marker.

Introduction and objective. Work noise exposure among farmers can cause hearing loss. Farmers are exposed to hazardous noise from equipment and domestic animals, and experience high rates of noise-induced hearing loss. The aim of our study was to evaluate the hearing thresholds of farmers in Korea. This study is the first to evaluate hearing impairment in Korean farmers nationwide. There have been few studies that have performed audiometric testing to measure hearing impairment at the national level in Korea. Materials and method. Through the Farm Work Safety Model Project among the 40 villages in which inhabitants received health check-ups from 2006–2008, 2,027 people from 35 villages were targeted (957 people in 16 villages in 2006, 436 people in five villages in 2007, and 634 people in 14 villages in 2008) and underwent pure tone audiometry tests. 2,027 people from 35 villages underwent pure tone audiometry tests through the Farm Work Safety Model Project. The tests were conducted using a portable audiometer, and air conduction thresholds were determined. Results. Hearing impairment at 3kHz and above was more prevalent in men than in women. The prevalence of moderate- to-profound hearing impairment was 19.6% in the total study population and increased with age. Conclusions. It is proposed that the high prevalence rate of farmers’ hearing impairment may be due to excessive workplace noise. To manage farmers’ hearing health, precise evaluations of farmers’ hearing acuity and noise exposure on farms should be conducted. This study might be a stepping-stone to protect farmers’ hearing health.

Opis:
Introduction. Lyme borreliosis (LB) is endemic spirochetosis with a transmission mechanism, which is often marked by a durable, recurrent course with multiple organ damages. LB is characterized by the appearance of migrating erythema at the site of tick bite. Durable persistence of the agent promotes disease progressing and occurrence of serious complications related to the nervous system, the heart and the locomotive apparatus. Among infrequent and especially dangerous complications of LB is damage to the hearing apparatus with the development of sensorineural deafness – hearing loss, which develops within 24 hours due to function impairment of the internal ear or auditory nerve. That infectious diseases account for 12.8-13% of numerous causes of sensorineural deafness development. Most frequently, the disease caused by B. burgdorferi is mentioned. Aim. To analyze the clinical case of Lyme borreliosis complicated by the sensorineural hearing loss. Materials and methods. The analysis of clinical-laboratory and instrumental data of the patient with Lyme borreliosis, whose course of the disease was complicated by sensorineural hearing loss. The patient received care at Lviv Regional Infectious Diseases Clinical Hospital (LRIDCH). Results. The article presents a clinical case of Lyme borreliosis, complicated by sensorineural hearing loss, which appeared on the 15th day from the onset of erythema annulare in the patient. Hearing recovery in the patient could not be achieved via administration of etiotropic treatment (2.0 g/per day of ceftriaxone for 28 days), which was likely associated with late visit of the patient for medical aid. Conclusions. Sensorineural hearing loss is one of the rare, but severe lesions of auditory analyzer in LB. Hearing improvement after antibiotic therapy is possible in certain cases in early treatment.

Introduction: Surgical treatment of deafness by cochlear implants is used for more than 40 years, and during this period permanently, gradual and significant expansion of indications for this surgery has been observed. Material and methods: In our Department in the years 1994-2018 1480 cochlear implantations were performed, both in adults (647) and in children (883). In this study current indications and the rules for eligibility of patients based on 25 years of experience are presented. Results: Indications for cochlear implantation in adults are: 1) bilateral postlingual deafness, 2) bilateral sensorineural hearing loss - in pure tone audiometry > 70 dB HL (average 500-4000 Hz) and in speech audiometry in hearing aids understanding < 50% of words for the intensity of the stimulus 65 dB, in the absence of the benefits of hearing aids, 3) bilateral profound hearing loss for high frequency with good hearing for low frequency, in the absence of the benefits of hearing aids, 4) some cases of asymmetric hearing loss with intensive tinnitus in the deaf ear. An indication in children is bilateral sensorineural hearing loss > 80dB HL confirmed by hearing tests, after about 6 months of rehabilitation with the use of hearing aids. Discussion: Although cochlear implantation is used for more than 40 years, the indications for this treatment underlies constant modifications. They concern the age of eligible patients, implantation in patients with partially preserved hearing, as well as treatment for patients with difficult anatomical conditions. In many countries, bilateral implantations are commonly performed, and more and more centers recommend this treatment in the case of unilateral deafness or asymmetric hearing loss, especially with the accompanying tinnitus in the deaf ear.

Opis:
The article shows 2 cases of unusual presentation of acute acoustic trauma and blast injury due to occupational exposure. In the case of both patients the range of impaired frequencies in pure tone audiograms was atypical for this kind of causative factor. Both patients had symmetrical hearing before the accident (which was confirmed by provided results of hearing controls during their employment). A history of noise/blast exposure, the onset of symptoms directly after harmful exposure, symmetrical hearing before the trauma documented with audiograms, directed initial diagnosis towards acoustic/blast trauma, however, of atypical course. Acute acoustic and blast trauma and coexisting acoustic neuroma (AN) contributed to, and mutually modified, the course of sudden hearing loss. In the literature there are some reports pointing to a higher sensitivity to acoustic trauma in the case of patients with AN and, on the other hand, indicating noise as one of the causative factors in AN.

Opis:
The aim of the study was to evaluate the combined effect of noise exposure and additional risk factors on permanent hearing threshold shift. Three additional risk factors were: exposure to organic solvents, smoking and elevated blood pressure. The data on exposure and health status of employees were collected in 24 factories. The study group comprised of 3741 noise male exposed workers of: mean age 39§8 years, mean tenure 16§7 years and LEX;8h = 86 § 5 dB. For each subject, hearing level was measured with pure tone audiometry, blood pressure and noise exposure were assessed from the records of local occupational health care and obligatory noise measurements performed by employers. Smoking and solvent exposure were assessed with questionnaire. The study group was divided into subgroups with respect to the considered risk factors. In the analysis, the distribution of hearing level of each subgroup was compared to the predicted one which the standard calculation method described in ISO 1999:1990. For each of the considered risk factors, the difference between measured and calculated hearing level distribution was used to establish, by the least square method, a noise dose related correction square function for the standard method. The considered risk factors: solvent exposure, smoking and elevated blood pressure combined with noise exposure, may increase degree of hearing loss.

Introduction: The Polish Universal Neonatal Hearing Screening Program (PUNHSP) is one example of a nationwide pro-health program in Poland. This program is aimed at early diagnosis and intervention in children with hearing impairment, and is an example of a well-managed program. Presenting the results of the PUNHSP, particularly organisational aspects and experience, can assist institutions managing other programs to achieve high efficiency. The aim of this work was to perform a detailed analysis of the PUNHSP by identifying the changes implemented over the 15 years it has been active, as well as the consequences of their introduction in terms of improved quality and efficiency. Materials and methods: Data from the PUNHSP, registered in the central database, were evaluated, as well as organisational information related to management, IT support and infrastructure. The analysis was based on quality assessment parameters (identification of changes and the purpose of their introduction) and effectiveness (consequences of introducing the changes). The analysis includes the 15-year period in which the PUNHSP has been active, from 2002 to 2017. Results: Thirteen main modifications of the program were identified according to the definition of “change”, in addition to 11 smaller modifications resulting from the necessity to adapt to current requirements. The changes were grouped into five categories: legal, administrative, management, audit and control, and IT. Discussion: The changes implemented in the PUNHSP can be assumed to have positively influenced various aspects of the program, but do not exhaust the possibilities for further optimisation of functioning. Conclusions: The program requires constant development in order to increase the efficiency and effectiveness of its operation, and the changes and solutions implemented in this program could be applied to improve existing pro-health programs, as well as those yet to be created.

Opis:
Hearing impairment caused by noise, traditionally called – depending on the duration of exposure - acute or chronic acoustic trauma, includes, in addition to presbyacusis, the most common adult population of hearing impaired. In Poland - according to the report of the Central Statistical Office (GUS, 2011), the number of workers employed in NDN exceeded the noise level (85 dB) is about 200 thousand, the highest in the mining, metal and metal products production, textiles and wood production. According to the Regulation of the Council of Ministers of on June 30, 2009, on the list of occupational diseases (Journal of Laws No. 132, item 1115), it is defined as "bilateral permanent hearing loss of the cochlear or sensory-nerve type, expressed as an increase in hearing threshold of at least 45 dB in the ear better heard, calculated as an arithmetic mean for frequencies 1,2 and 3 kHz. Hearing impairments also occur in the military and police during field training and in combat where the source of acoustic injuries are firearms and pulse-inducing explosions (as in some industries) with high C peak levels (Lc peak) Time to rise to a maximum of <1 ms. The prevalence of loud music listening, particularly by personal stereo players, is also affecting children and adolescents with audiometric hearing loss, according to the World Health Organization (WHO) estimates of around 15-20%. The preventive action strategy is defined by the European Union legislation and the national implementing legislation that reduces or eliminates the risk and reduces (if not eliminated), taking into account available technical and organizational solutions to minimize the risk of hearing damage. If you can not reduce the noise levels with technical and organizational methods, you need individual hearing protectors. Ear protectors may be equipped with electronic systems with active noise reduction (which can improve low and medium frequency performance), adjustable attenuation (improves speech intelligibility and perception of warning signals), and wireless communication for verbal communication.

Opis:
If we want to provide the efficient training intervention to increase the duration of using heating protection devices (HPDs) by workers, we need a tool that can estimate the person’s hearing threshold taking into account noise exposure level, age, and work history, and compare them with audiometry to find out the percent reduction of workers hearing loss. First, the workers noise exposure level was determined according to ISO 9612, then 4000 Hz audiometry was done to find age and work history. On basis of ISO 1999 the hearing threshold was estimated and if the hearing protection device was not used continuously and correctly, the hearing protection device’s actual performance was reduced adjusted with person’s audiometry. After training intervention, the estimate was done again and was compared with the adjusted audiometry. According to ISO 1999 standard estimation results, the percent reduction of the workers hearing loss level was 6.48 dB in intervention group. This level remained unchanged in control group. The mean score of hearing threshold estimation (standard ISO 1999) was statistically more significant than mean score of hearing threshold (p-value ¡ 0.001). The results show not significant change in control group due to Lack of changing of noise exposure level. In regards to the results of hearing threshold estimation based on ISO 1999 and comparing with workers audiometry, it can be seen that BASNEF training intervention increases the duration of Rusing the HPDs and it could be effective in reducing hearing threshold related to noise.

Opis:
Sudden onset sensorineural hearing loss is an emergency condition in otorhinolaryngology. Despite its common occurrence, the investigation and treatment of this condition are still controversial. Auditory brainstem response is one of hearing assessment tools used in sudden onset sensorineural hearing loss. However, its findings may be false positive at early stages of the disorder, leading to unnecessary investigations and treatments. We report two cases of idiopathic sudden onset sensorineural hearing loss, which manifested in abnormal auditory brainstem response during the acute phase of illness. However, a complete recovery of auditory brainstem response was observed after treatment completion. Therefore, we suggest that auditory brainstem response should be performed reasonably, especially during the acute phase of sudden onset sensorineural hearing loss.
Nagły idiopatyczny niedosłuch czuciowo-nerwowy jest stanem nagłym w otorynolaryngologii. Pomimo częstego występowania badanie i leczenie tego zaburzenia nadal budzą kontrowersje. Jednym z narzędzi diagnostycznych stosowanych u pacjentów z nagłym idiopatycznym niedosłuchem czuciowo-nerwowym jest pomiar słuchowych potencjałów wywołanych pnia mózgu. Badanie to może jednak dawać wyniki fałszywie dodatnie we wczesnych stadiach choroby, prowadząc w konsekwencji do niepotrzebnych dalszych badań i prób leczenia. W pracy przedstawiono dwa przypadki nagłego idiopatycznego niedosłuchu czuciowo-nerwowego objawiającego się nieprawidłowościami w zapisie słuchowych potencjałów wywołanych pnia mózgu podczas ostrej fazy choroby. Po zakończeniu leczenia stwierdzono całkowite przywrócenie słuchu w badaniu słuchowych potencjałów wywołanych pnia mózgu. Autorzy zalecają wykonywanie tego badania w sposób racjonalny, w szczególności podczas ostrej fazy choroby.

Opis:
Introduction: It is estimated that hearing impediment affects approximately 12% of the population. Some forms of hearing disorders can be successfully treated conservatively, while in others surgery plays a key role. Often, therapeutic methods are exhausted and the patient faces the decision about the need for acoustic organ prosthesis. Depending on the causes of anomalies, apparatus for air conduction, bone conduction or cochlear implants are used. A cochlear implant replaces the damaged sensory cells of the inner ear. It constitutes an electronic prosthesis of the acoustic organ, composed of two parts. The internal part (implanted in the inner ear) consists of an implant and electrodes, which conduct electrical signals to the cochlea. The external part consists of a microphone, a speech processor, and a transmitter. Care report: A 70-year-old patient with deep hearing loss in the right ear and deafness of the left ear. During the interview, the patient denied mechanical injuries of the head and neck, acoustic trauma, inflammation or otorrhea. Based on the conducted tests, qualification otolaryngology, audiology, and otoneurology, radiology, surdologopedy and psychology were performed for cochlear implant insertion. The patient was qualified for cochlear implantation in the left ear under general anesthesia. The surgical team was composed of dr hab. Maciej Wiatr, prof. dr hab. Kazimierz Niemczyk, prof. dr hab. Jacek Składzień, MD Agnieszka Wiatr with anesthetic monitoring under the supervision of MD Renata Witkowska. The patient was discharged home on day 7 after surgery in good general and local condition. Simultaneous rehabilitation was started at the Center for Daily Rehabilitation of Hearing and Speech at the Specialist Center of Diagnosis and Rehabilitation for Children and Adolescents with Hearing Disabilities of the Polish Association of the Deaf in Cracow.

Background: Patients with vestibular schwannoma (VS) most commonly present with hearing threshold reduction for high frequencies and a falling type of audiometric curve. However, it is doubtful whether all Pure Tone Averages described in the literature characterize patients with VS correctly, as the type of PTA which comprises higher frequencies may be more appropriate for hearing status assessment in those patients. Aim: The aim of this study was to analyze 3 common methods of calculating Pure Tone Averages (PTA1 – 500, 1000, 2000 and 3000 Hz; PTA2 – 500, 1000, 2000 and 4000 Hz; PTA3 – 500, 1000 and 2000 Hz) and to determine which of them is the most reliable for the assessment of VS patients. Material and Methods: The study group included 86 patients operated on due to vestibular schwannoma accessed via the middle cranial fossa. Results: Regarding the method of calculating Pure Tone Averages (PTA1, PTA2 and PTA3) identical or similar correlations were found between the preoperative values of Pure Tone Averages (PTA1, PTA2 and PTA3) and surgery-related hearing loss, as well as individual parameters of audiologic tests. Conclusions: Pure Tone Averages calculated according to 3 different methods (PTA1, PTA2, PTA3) may be used interchangeably in the assessment of hearing in VS patients.

Opis:
In this paper, we discuss the issue of hearing damage caused by noise in classical musicians. Long-term exposure to highintensity sounds leads to degenerative changes at the level of the cochlea and then in the higher parts of the auditory canal. This is particularly unfavorable for musicians because an efficient hearing organ is necessary for them to perform their daily work. The risk of hearing damage depends on noise parameters and intrinsic factors referred to as individual noise sensitivity. Not all musicians are exposed to sounds that exceed the acceptable level. However, most of them work at noise levels that are close to or above the acceptable safety limit, thus posing a health threat. In addition to hearing threshold elevation, tinnitus, hyperacusis, and diplacusis may result following many years of exposure to high-intensity acoustic stimuli. Although the differences between the hearing thresholds for instrumentalists and members of the unexposed population are not large, researchers emphasize the need to recognize musicians as a risk group and to apply appropriate prevention. One of the methods to prevent hearing damage is to use ear protectors, which, although effectively reduce exposure, are not widely used by instrumentalists as they impede auditory control over the sounds produced by the instrument. In addition, multifaceted prevention programs and various techniques to minimize exposure are used, such as the proper placement of loud instruments in an orchestra.

Introduction: Nowadays, there are many options to treat hearing-impaired patients: tympanoplastic surgery, hearing aids and a wide range of implantable devices. Aim: The aim of this study is to present the mid-term audiological and quality of life benefits after the implantation of Osia®, an active piezoelectric bone conduction hearing implant. Material and methods: The state of the tissues in the implanted area, as well as audiological and quality of life results were analyzed at six, nine and twelve months after implantation in a group of four adult patients with bilateral mixed hearing loss (1 after bilateral canal-wall-down mastoidectomy, 2 with chronic simple otitis media and after myringoplasty in the opposite ear, 1 with bilateral otosclerosis and after stapedotomy in the opposite ear). Results: No postoperative complications were found in any of the cases. One year after surgery the mean audiological gain in FF PTA4 (pure tone average for 0.5, 1, 2, and 4 kHz) was 52.2 ± 3.5 dB in comparison to the unaided situation, the mean speech understanding with Osia® in quiet was 90 ± 8.2% for 50 dB SPL, 98.8 ± 2.5% for 65 dB SPL and 100 ± 0% for 80 dB SPL, and the mean speech understanding with Osia® in noise was 37.5% ± 23.6 for 50 dB SPL, 93.8 ± 4.8% for 65 dB SPL and 98.8 ± 2.5% for 80 dB SPL. There was also an evident improvement in the quality of hearing as well as in the quality of life, measured by APHAB (Abbreviated Profile of Hearing Aid Benefit) and SSQ (Speech, Spatial and Qualities of Hearing Scale). Conclusions: The Osia® is an effective treatment option for patients with bilateral mixed hearing loss. The mid-term audiological and quality of life results are excellent, but further observations including bigger groups of patients and a longer follow-up are required.

Introduction: Stapedotomy is currently the surgical technique of choice for treating otosclerosis. Despite this, there is no agreement about the best technique to perform a small fenestra footplate, therefore multiple procedures have been proposed. The aim of this study was to investigate the hearing outcomes of microdrill and manual perforator. Material and Methods: An observational prospective study was carried out on patients who underwent stapedotomy. We analyzed the hearing threshold in two groups of patients according to the way the fenestra footplate was realized by microdrill or manual perforator. Results: A total of 113 patients were evaluated. Postoperative hearing gain of the microdrill group was 23.29 (18.58) dB HL 95% CI (18.40–28.18), while in the manual perforator group, it was 22.67 (12.91) dB HL 95% CI (19.07–26.26). Both groups were statistically significant. Postoperative bone conductive hearing threshold at the frequencies of 0.5, 1 and 2 KHz and postoperative air conductive hearing threshold at the frequencies of 2 and 4 KHz showed statistically significant differences in the manual perforator group. The closure of air-bone gap was higher in the microdrill group with statistically significant differences. Conclusion: Both manual perforator and microdrill have good hearing outcomes at six months after surgery. The manual perforator has better audiological outcomes than microdrill. Hence, the manual perforator is a safe technique and can be used in centers that do not have other methods to make the small fenestra.

Opis:
Evaluation of acoustic vestibular evoked myogenic potentials (AC-VEMPs) is one of the tests performed to assess the function of the balance system. Evaluation of acoustic ocular vestibular evoked myogenic potentials (AC-oVEMPs) consists in the measurement of potentials evoked within oculomotor muscles, particularly the inferior oblique muscles (the most superficial muscles) with impulses being transmitted along the superior branch of the vestibular nerve from the utricular macula. Despite the fact that the measurement of oVEMPs was introduced relatively recently, it has found widespread use as a diagnostic tool in otology and neurotology. Despite the growing number of literature reports, the methodology of the test and the methods for the interpretation of its results are still subject to debate. This article is dedicated to various aspects of AC-oVEMP tests, including the methodology of the test, interpretation of its results and potential use in the diagnostics of vertigo.

Opis:
Background: Hearing loss caused by excessive exposure to noise is one of the most common health risks for employees. One solution for noise reduction is the use of hearing protectors, which is a very effective method for protecting hearing from the workplace noise. In order to obtain better attenuation efficiency, custom moulded earplugs can be equipped with a suitable acoustic filter. The effectiveness of the hearing protectors’ attenuation is based on real measurement of hearing thresholds for normal hearing people with and without hearing protectors. However, this is a time consuming process, and the obtained values are characterised by quite large inter-individual variability. The optimal solution is to measure the attenuation characteristics based on the objective method (without the presence of the subject), the results of which will be in accordance with the results of subjective tests. Therefore, the main purpose of the research in this work was to measure the attenuation characteristics of the self-designed custom moulded earplugs with and without acoustic filters through the use of subjective and objective methods, and to compare the results in terms of the research methods. Methods: Measurements of the acoustic attenuation obtained by custom moulded earplugs with designed F1, F2, and F3 acoustic filters (internal diameters dF1 = 1:25 mm, dF2 = 0:85 mm, and dF3 = 0:45 mm), as well as full insert earplugs (without any acoustic filters) were carried out using two methods: objective and subjective. The objective measurements were carried out in an anechoic chamber. The artificial head (High-frequency Head and Torso Simulator Brüel & Kjær Type 5128) was located at a distance of 3 m, directly opposite the loudspeaker. The test signal in the measurements was pink noise – in the frequency range up to 12.5 kHz and the level 85, 90, and 95 dB. The hearing protectors with and without acoustic filters were mounted in the Head and Torso Simulator which was connected with Pulse System Brüel & Kjær. Five normal hearing subjects participated in the subjective measurements. A pink noise signal was used for one-third octave bands: 125, 250, 500, 1000, 2000, 4000, and 8000 Hz. The attenuation value was defined as the difference (in dB) between the hearing threshold of the test signal with a hearing protector and the hearing threshold determined without a hearing protector. Results: The results of the objective method proved that in addition to the significant impact of frequency on the attenuation values, the type of filter used in custom moulded earplugs also had a significant effect. In addition, the results of the objective method showed that in the whole frequency range the highest attenuation values are shown by the full earplugs, achieving slightly above 45 dB for frequency of 8 kHz. The attenuation values obtained from subjective measurements also confirmed that both the frequency and type of filter significantly affect the attenuation values of the tested hearing protectors. Conclusions: The results of this study did not confirm the hypothesis that the measurement method had no significant effect on the attenuation characteristics of self-designed custom moulded earplugs with different types of acoustic filters. The largest differences in attenuation values between the type of measurement methods occur for the low frequency band (250 Hz) and for higher frequencies (4000 Hz mainly). The change of the internal diameter of the F1 filter from 1.25 mm to 0.85 mm (F2 filter) did not significantly affect the attenuation characteristics.

Shooting training is associated with exposure to a considerable amount of unique noise. We wanted to evaluate noise exposure during such training. Our observations especially apply to professional sport shooters, but they are also valid for shooting coaches/instructors. We collected acoustic signals in 10-, 25- and 50-m as well as open-air shooting ranges. The recorded material was analysed with orthogonal, adaptive parameterization by Shur. The mean duration of a single acoustic signal was 250–800 ms with the C-weighted sound peak pressure level of 138.2–165.2 dB. Shooters may be exposed to as many as 600–1350 acoustic impulses during a training unit. The actual load for the hearing organ of a professional shooter or a shooting coach is ~200 000 acoustic stimuli in a year-long training macrocycle. Orthogonal, adaptive parameterization by Shur makes safe scheduling of shooters’ training possible.

Objective: A pure tone audiomety analysis of patients with extracranial complications of chronic suppurative otitis media (ECCSOM). Material and methods: We retrospectively analyzed audiometric data performed before treatment from 63 patients with ECCSOM (56 single, 7 multiple complications) including groups of frequencies. Results: The greatest levels of hearing loss were noted for 6 and 8 kHz (79.0 and 75.7 dBHL) and for the frequency groups high tone average (76.1 dBHL). As regards the severity of hearing impairment in pure tone average the prevalence of complications was as follows: labyrinthitis (77.8±33.6 dBHL), facial palsy (57.1±14.3 dBHL), perilymphatic fistula (53.9±19.9 dBHL) and mastoiditis (42.2±9.5 dBHL) (p=0.023). Conclusions: Hearing loss in ECCSOM is dominated by mixed, high-tone, moderate type of hearing loss, most profound in labyrinthitis. In 11% of patients the complication causes total deafness.
