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:
This study is a meta-analysis of the previous epidemiological studies which investigated the quantitative estimates of the association between independent or combined exposure to noise and mixed organic solvents and hearing loss until October 2014. Overall, 15 studies with information on 7530 individuals (6% female) were included. Having assessed – by puretone audiometry – the adjusted odds ratio estimates for the association between solvents mixture exposure and the risk of developing hearing loss stood at 2.05 (95% confidence interval (CI): 1.44–2.9). Similarly, for subjects who were concurrently exposed to noise and solvents mixture, an OR of 2.95 (95% CI: 2.1–4.17) was obtained. There was some evidence of heterogeneity within each of the 2 exposure groups (p heterogeneity < 0.001). This heterogeneity was not explained by differences in strength of effect between duration of exposure, the number of solvent and exposure index in subgroups of solvents mixture exposure. Based on the available data, our analysis has provided the evidence of increased risk of developing hearing loss for workers exposed to organic solvents even at quite low concentration. Moreover, if such exposure is accompanied by noise, it will exacerbate the extent of hearing loss. Int J Occup Med Environ Health 2017;30(4):521–535

Opis:
Objectives Hearing loss is a major worldwide health issue affecting an estimated 1.5 billion people. Causes of hearing loss include genetics, chemicals, medications, lifestyle habits such as smoking, and noise. Noise is probably the largest contributing factor for hearing loss. Noise arises from the workplace, ambient environment, and leisure activities. The easiest noise sources to control are workplace and environmental. Workplace noise is unique in that the employer is responsible for the noise and the worker. Also, workers may be exposed to much higher levels of noise than they would accept elsewhere. Employers follow the traditional hierarchy of controls (substitution/engineering, administrative, personal protective equipment [PPE]). Substituting or engineering a lower noise level actually reduces the hazard present to the worker but demand more capital investment. Administrative and PPE controls can be effective, but enforcement and motivation are essential to reducing risk and there is still some hearing loss for a portion of the workers. The challenge is to estimate the costs more clearly for managers. A systems engineering approach can help visualize factors affecting hearing health. Material and Methods In this study, a systems engineering causal loop diagram (CLD) was developed to aid in understanding factors and their interrelationships. The CLD was then modeled in VenSim. The model was informed from the authors’ expertise in hearing health and exposure science. Also, a case study was used to test the model. The model can be used to inform decision-makers of holistic costs for noise control options, with potentially better hearing health outcomes for workers. Results The CLD and cost model demonstrated a 4.3 year payback period for the engineered noise control in the case study. Conclusions Systems thinking using a CLD and cost model for occupational hearing health controls can aid organizational managers in applying resources to control risk.

Objectives The objective of this study has been to test 2 spreadsheet models to compare the observed with the expected hearing loss for a Norwegian reference population. Material and Methods The prevalence rates of the Norwegian and the National Institute for Occupational Safety and Health (NIOSH) definitions of hearing outcomes were calculated in terms of sex and age, 20–64 years old, for a screened (with no occupational noise exposure) (N = 18 858) and unscreened (N = 38 333) Norwegian reference population from the Nord-Trøndelag Hearing Loss Study (NTHLS). Based on the prevalence rates, 2 different spreadsheet models were constructed in order to compare the prevalence rates of various groups of workers with the expected rates. The spreadsheets were then tested on 10 different occupational groups with varying degrees of hearing loss as compared to a reference population. Results Hearing of office workers, train drivers, conductors and teachers differed little from the screened reference values based on the Norwegian and the NIOSH criterion. The construction workers, miners, farmers and military had an impaired hearing and railway maintenance workers and bus drivers had a mildly impaired hearing. The spreadsheet models give a valid assessment of the hearing loss. Conclusions The use of spreadsheet models to compare hearing in occupational groups with that of a reference population is a simple and quick method. The results are in line with comparable hearing thresholds, and allow for significance testing. The method is believed to be useful for occupational health services in the assessment of risk of noise induced hearing loss (NIHL) and the preventive potential in groups of noise-exposed workers.

Opis:
Tinnitus is defi ned as a perception of sound in the absence of an external acoustic stimulus. Several factors are known to infl uence tinnitus, e.g. hearing loss, noise exposure, age, and hypertension. As only certain individuals develop tinnitus in the presence of the above risks and in approximately 50% of cases tinnitus is not attributed to any particular cause, the question arose whether this inter-individual susceptibility to tinnitus could be explained by the infl uence of genetic factors. Objectives: To test the hypothesis that genetic variability in genes of the potassium recycling pathway is associated with increased susceptibility to tinnitus. Materials and Methods: The study group consisted of 626 subjects exposed to occupational noise (128 with tinnitus and 498 without tinnitus). 99 single nucleotide polymorphisms were investigated in 10 genes involved in the potassium recycling pathway in the inner ear, previously selected as putative noise-induced hearing loss (NIHL) candidate genes. Results: Nominally signifi cant associations were obtained for 2 variants in KCNE1 (potassium voltage-gated channel, Isk-related family, member 1) and SLC12A2 (solute carrier family 12, member 2) genes. The first gene contributed to tinnitus that developed independently of hearing loss, while the second one was associated with increased susceptibility to noise-induced hearing loss. Conclusions: Present fi ndings lend support to the notion of potassium recycling pathway genes as possible risk modifi ers of tinnitus in individuals with and without hearing loss. Due to the lack of replication in other independent populations these results should be seen as suggestive.

Opis:
Objectives It has been shown that monitoring temporary threshold shift (TTS) after exposure to noise may have a predictive value for susceptibility of developing permanent noise-induced hearing loss. The aim of this study is to present the assumptions of the TTS predictive model after its verification in normal hearing subjects along with demonstrating the usage of this model for the purposes of public health policy. Material and Methods The existing computational predictive TTS models were adapted and validated in a group of 18 bartenders exposed to noise at the workplace. The performance of adapted TTS predictive model was assessed by receiver operating characteristic (ROC) analysis. The demonstration example of the usage of this model for estimating the risk of TTS in general unscreened population after exposure to loud music in discotheque bars or music clubs is provided. Results The adapted TTS predictive model shows a satisfactory agreement in distributions of actual and predicted TTS values and good correlations between these values in examined bartenders measured at 4 kHz, and as a mean at speech frequencies (0.5–4 kHz). An optimal cut-off level for recognizing the TTS events, ca. 75% of young people (aged ca. 35 years) may experience TTS >5 dB, while <10% may exhibit TTS of 15–18 dB. Conclusions The final TTS predictive model proposed in this study needs to be validated in larger groups of subjects exposed to noise. Actual prediction of TTS episodes in general populations may become a helpful tool in creating the hearing protection public health policy. Int J Occup Med Environ Health. 2023;36(1):125–38

Objectives The aim of this study was to assess hearing of music students in relation to their exposure to excessive sounds. Material and Methods Standard pure-tone audiometry (PTA) was performed in 168 music students, aged 22.5±2.5 years. The control group included 67 subjects, non-music students and non-musicians, aged 22.8±3.3 years. Data on the study subjects’ musical experience, instruments in use, time of weekly practice and additional risk factors for noise-induced hearing loss (NIHL) were identified by means of a questionnaire survey. Sound pressure levels produced by various groups of instruments during solo and group playing were also measured and analyzed. The music students’ audiometric hearing threshold levels (HTLs) were compared with the theoretical predictions calculated according to the International Organization for Standardization standard ISO 1999:2013. Results It was estimated that the music students were exposed for 27.1±14.3 h/week to sounds at the A-weighted equivalent-continuous sound pressure level of 89.9±6.0 dB. There were no significant differences in HTLs between the music students and the control group in the frequency range of 4000–8000 Hz. Furthermore, in each group HTLs in the frequency range 1000–8000 Hz did not exceed 20 dB HL in 83% of the examined ears. Nevertheless, high frequency notched audiograms typical of the noise-induced hearing loss were found in 13.4% and 9% of the musicians and non-musicians, respectively. The odds ratio (OR) of notching in the music students increased significantly along with higher sound pressure levels (OR = 1.07, 95% confidence interval (CI): 1.014–1.13, p < 0.05). The students’ HTLs were worse (higher) than those of a highly screened non-noise-exposed population. Moreover, their hearing loss was less severe than that expected from sound exposure for frequencies of 3000 Hz and 4000 Hz, and it was more severe in the case of frequency of 6000 Hz. Conclusions The results confirm the need for further studies and development of a hearing conservation program for music students. Int J Occup Med Environ Health 2017;30(1):55–75

ObjectivesThe aim of the study was to evaluate the hearing status of operators of low-frequency ultrasonic devices compared to employees exposed to audible noise at a similar A-weighted sound pressure level (SPL) but without ultrasonic components.Material and MethodsStandard pure-tone audiometry, extended high-frequency audiometry (EHFA), transient-evoked otoacoustic emissions (TEOAE), and distortion-product otoacoustic emissions (DPOAE), as well as questionnaire surveys were conducted among 148 subjects, aged 43.1±10.8 years, working as ultrasonic device operators for 18.7±10.6 years. Their exposure to noise within the ultrasonic and audible frequency range was also evaluated. The control group comprised 168 workers, adjusted according to gender, age (±2 years), tenure (±2 years), and the 8-hour daily noise exposure level (LEX,8h) of ±2 dB.ResultsThe ultrasonic device operators and the control group were exposed to audible noise at LEX,8h of 80.8±3.9 dB and 79.1±3.4, respectively. The Polish maximum admissible intensity (MAI) values for audible noise were exceeded in 16.8% of the ultrasonic device operators, while 91.2% of them were exposed to ultrasonic noise at SPL>MAI values. There were no significant differences between the groups in terms of the hearing threshold levels (HTLs) up to 3 kHz, while the ultrasonic device operators exhibited significantly higher (worse) HTLs, as compared to the control group, in the range of 4–14 kHz. The results of the DPOAE and TEOAE testing also indicated worse hearing among the ultrasonic device operators. However, the differences between the groups were more pronounced in the case of EHFA and DPOAEs.ConclusionsThe outcomes of all hearing tests consistently indicated worse hearing among the ultrasonic device operators as compared to the control group. Both EHFA and DPOAE seem to be useful tools for recognizing early signs of hearing loss among ultrasonic device operators.

Opis:
W 2019 r. choroba spowodowana SARS-CoV-2 – COVID-19 – wywołała wciąż trwającą pandemię. Do najczęstszych objawów klinicznych zakażenia SARS-CoV-2 należą: gorączka, suchy kaszel, zmęczenie, bóle mięśniowe, problemy z oddychaniem, utrata węchu i/lub smaku. Inne dolegliwości, w tym ze strony narządu słuchu i równowagi, np. niedosłuch, szumy uszne czy zawroty głowy, zgłaszane są przez chorych rzadziej. Jako pierwsze objawy tej infekcji bywają wskazywane sporadycznie. Chcąc odpowiedzieć na pytanie, czy SARS-CoV-2 może być przyczyną uszkodzenia słuchu i równowagi, autorzy dokonali przeglądu piśmiennictwa z lat 2019–2020 w bazach EMBASE i PubMed, wpisując hasła: „hearing loss”, „COVID-19”, „corona virus”, „sensorineural hearing loss”, „vertigo”, „dizziness”. Do opracowania zakwalifikowano 9 prac dotyczących potencjalnego związku uszkodzenia słuchu z SARS-CoV-2 oraz 4 prace omawiające ewentualne zaburzenia równowagi na skutek infekcji SARS-CoV-2. Wyniki analizy wskazują na możliwe istnienie związku pomiędzy COVID-19 a uszkodzeniem słuchu przy jednoczesnym braku dowodów na istnienie podobnej relacji między przebytą infekcją tym wirusem a układem równowagi. O tej prawdopodobnej zależności – zwłaszcza o możliwości wystąpienia nagłego niedosłuchu czuciowo-nerwowego jako pierwszego objawu COVID-19 – powinni szczególnie pamiętać lekarze szpitalnych izb przyjęć, otolaryngolodzy i audiolodzy. Dotyczy to również lekarzy innych specjalności. Autorzy wskazują potrzebę prowadzenia dalszych, intensywnych, wielopłaszczyznowych badań nad tym zagadnieniem. Med. Pr. 2021;72(3):321–325
In 2019, COVID-19, the disease caused by the SARS-CoV-2 virus, evolved into a pandemic which is still going on. The basic clinical symptoms of the SARS-CoV-2 infection are: fever, dry cough, fatigue, muscle pain, respiratory problems, and the loss of smell or taste. Other symptoms, including those related to hearing and balance organs (hearing loss, tinnitus, dizziness), are reported less frequently by patients. They are especially rarely reported as the first symptoms of this infection. In order to answer the question of whether SARS-CoV-2 can cause hearing and balance damage, the authors reviewed the literature sources from 2019–2020 included in EMBASE and PubMed, entering the following words: “hearing loss,” “COVID-19,” “coronavirus,” “sensorineural hearing loss,” “vertigo,” and “dizziness.” Ultimately, 9 studies on the possible relationship between hearing impairment and SARS-CoV-2, and 4 studies on the possible relationship between damage to the balance and SARS-CoV-2, were qualified for the study. The results of the analysis suggest a possible relationship between COVID-19 and hearing loss, with no evidence of a similar relationship between this virus and the balance system. The possible existence of such a relationship should be especially remembered by hospital emergency room doctors, otolaryngologists and audiologists, especially as regards the possibility of a sudden sensironeural hearing loss as the first symptom of COVID-19. This also applies to doctors of other specialties. The authors indicate the need for further, intensive and multifaceted research on this issue. Med Pr. 2021;72(3):321–5

W związku z wykazanymi właściwościami ototoksycznymi rozpuszczalników organicznych w Dyrektywie 2003/10/WE Parlamentu Europejskiego i Rady Unii Europejskiej zalecono, aby w szacowaniu ryzyka zawodowego uszkodzenia słuchu brać pod uwagę interakcję skutków działania hałasu i rozpuszczalników na narząd słuchu. Uwzględniając brak sprecyzowanych do tej pory zaleceń profilaktycznych, niniejsze opracowanie ma na celu dostarczenie lekarzowi wskazówek w zakresie prowadzenia badań słuchu u pracowników eksponowanych na te zagrożenia. W tej pracy omówiono biologiczne skutki działania hałasu i rozpuszczalników organicznych na narząd słuchu oraz aktualne możliwości szacowania ryzyka uszkodzenia słuchu w przypadku izolowanego narażenia na rozpuszczalniki oraz ich współdziałania z hałasem. Przedstawiono zakres badania lekarskiego oraz znaczenie poszczególnych badań słuchu, w tym audiometrii tonalnej, otoemisji akustycznych, audiometrii impedancyjnej, słuchowych potencjałów wywołanych pnia mózgu, audiometrii mowy w ciszy, audiometrii mowy w szumie oraz dychotycznego testu cyfrowego w diagnostyce uszkodzeń spowodowanych przez rozpuszczalniki organiczne. Opracowano algorytm przeprowadzania badań słuchu w przypadku narażenia na rozpuszczalniki organiczne oraz hałas i rozpuszczalniki w zależności od poziomu narażenia. Wskazano konieczność corocznych badań audiometrycznych u wszystkich pracowników narażonych na rozpuszczalniki organiczne w przypadku przekroczenia ich stężeń w powietrzu, bezpiecznych dla narządu słuchu, niezależnie od współwystępowania narażenia na hałas. U osób narażonych na hałas i rozpuszczalniki organiczne okresowa audiometria tonalna powinna być obowiązkowo wykonywana już przy przekroczeniu wartości dolnego progu działania dla hałasu określonego w Dyrektywie 2003/10/WE, tj. LEX,8h = 80 dB. Biorąc pod uwagę działanie uszkadzające rozpuszczalników organicznych na część ośrodkową narządu słuchu, dodatkowo do audiometrii tonalnej zalecane jest badanie audiometrii mowy (optymalnie audiometrii mowy w szumie). Wprowadzenie profilaktycznych badań słuchu u pracowników narażonych na rozpuszczalniki organiczne oraz rozszerzenie wskazań i zakresu badań słuchu u osób eksponowanych łącznie na hałas i rozpuszczalniki jest warunkiem skutecznej profilaktyki uszkodzeń słuchu w tych grupach zawodowych.
Robust evidence confirms that occupational exposures to organic solvents are ototoxic and can aggravate the effects of noise on the auditory organ. Accordingly, Directive 2003/10/EC of the European Parliament and of the Council recommends that in assessing the risk of occupational hearing loss, the interaction of noise and organic solvents to hearing should be taken into account. Given that no prophylactic recommendations have been established to date, this study is intended to provide physicians with guidance in conducting audiometric tests in workers exposed to noise and organic solvents. The paper discusses the biological effects of noise and organic solvents on the auditory organ and current possibilities of estimating the risk of hearing loss due to isolated exposures to solvents, as well as combined exposures to these chemicals and noise. The scope of medical examination and the significance of individual hearing tests, such as pure-tone audiometry, impedance audiometry, auditory brainstem responses, speech in quiet and speech in noise audiometry, and dichotic digit test, in the diagnostics of solvent-induced hearing loss are presented. An algorithm for conducting hearing tests in workers exposed to organic solvents, and co-exposed to noise and organic solvents, has been proposed depending on the concentration of solvents and noise level. Shown also is the necessity to perform annual audiometric testing in all workers exposed to organic solvents whose concentration in the air exceeds values safe for hearing. In workers exposed to noise and organic solvents, audiometric examinations should be mandatory in all subjects in whom the level of noise exceeds the lower action level defined by Directive 2003/10/EC, which is LEX,8h = 80 dB. Taking into account the detrimental effects of organic solvents to central auditory pathways, in addition to pure-tone audiometry, speech audiometry (preferentially speech in noise) should be included. The introduction of preventive audiometric tests in workers exposed to organic solvents, along with an extension of indications and the scope of hearing tests in workers co-exposed to noise and solvents, is a prerequisite for effective prevention of occupational hearing loss in these professional groups.

Objectives The objective of this study was to assess the hearing of employees using communication headsets with regard to their exposure to noise. Material and Methods The study group comprised 213 employees, including 21 workers of the furniture industry, 15 court transcribers and 177 call center operators, aged 19–55 years, working with headsets for a period of up to 25 years. All the participants underwent a standard puretone audiometry, extended high-frequency audiometry (EHFA) as well as transient-evoked otoacoustic emissions (TEOAEs) and distortion-product otoacoustic emissions (DPOAEs). Noise exposure from headsets was evaluated using the microphone in a real ear technique according to PN-EN ISO 11904-1:2008. Results Personal daily noise exposure levels ranged 57–96 dB and exceeded 85 dB only in 1.4% of the call center operators. Forty-two percent of the participants had bilateral normal hearing in the standard frequency range of 250–8000 Hz, and 33% in the extended highfrequency range of 9–16 kHz. It was found that DPOAEs were present bilaterally in 59% of the participants. Reproducibility of TEOAE at >70% and signal-to-noise ratio at >6 was exhibited by 42% and 17% of them, respectively. The 3 subgroups of workers differed in age, gender, noise exposure and type of headsets in use. However, after adjusting for age and gender, significant differences between these subgroups in terms of hearing were mostly visible in EHFA. A significant impact of age, gender, daily noise exposure level and current job tenure on hearing tests results was also noted among the call center operators and the transcribers. The most pronounced were the effects of age and gender, whereas the impact of the daily noise exposure level was less evident. Conclusions It seems that EHFA is useful for recognizing early signs of noise-induced hearing loss among communication headset users. However, further studies are needed before any firm conclusions concerning the risk of hearing impairment due to the use of such devices can be drawn.

Wstęp Celem pracy była ocena narażenia na hałas i ryzyka uszkodzenia słuchu spowodowanego hałasem wśród użytkowników słuchawkowych zestawów komunikacyjnych lub słuchawek. Materiał i metody W grupie 74 pracowników (wiek: 31,8±7,3 roku), w tym personelu lotnictwa wojskowego (N = 12), transkrybentów (N = 18) i telemarketerów (N = 44), przeprowadzono pomiary hałasu i badania kwestionariuszowe. Poziomy dźwięku emitowanego przez słuchawkowe zestawy komunikacyjne (lub słuchawki) zmierzono z zastosowaniem techniki microphone in the real ear (MIRE) i techniki sztucznego ucha, odpowiednio, według norm PN-EN ISO 11904-1:2008 i CSA Z107.56-13. Ryzyko uszkodzenia słuchu wywołanego hałasem oszacowano zgodnie z wytycznymi normy PN-ISO 1999:2000. Wyniki Mierzone pod słuchawkami i słuchawkowymi zestawami komunikacyjnymi z zastosowaniem technik MIRE i sztucznego ucha wartości równoważnego poziomu dźwięku A (odpowiadającego warunkom pola rozproszonego) wynosiły, odpowiednio, 67–86 dB (10–90 percentyl) i 68–89 dB (10–90 percentyl). Badani pracownicy używali tych urządzeń średnio przez 1,5–8 godz. dziennie (10–90 percentyl). Ekspozycja na takie poziomy dźwięku przez 40 lat pracy wiąże się z ryzykiem uszkodzenia słuchu (średni próg słuchu dla częstotliwości 2, 3 i 4 kHz > 25 dB) sięgającym 10–12% (technika MIRE) lub 19–22% (technika sztucznego ucha). Wartości indywidualnego dziennego poziomu ekspozycji na hałas w badanej grupie wynosiły 71–85 dB (10–90 percentyl). Część pracowników skarżyła się na problemy z rozumieniem mowy w hałaśliwym otoczeniu (28,4%) i słyszeniem szeptu (16,2%) oraz zauważyła przejściowe skutki słuchowe po pracy z zastosowaniem słuchawkowych zestawów komunikacyjnych lub słuchawek (16,2–25,7%). Wnioski Wskazane jest objęcie użytkowników słuchawkowych zestawów komunikacyjnych i słuchawek programem ochrony słuchu oraz kontynuowanie badań wśród pracowników innych branż. Med. Pr. 2019;70(1):27–52
Background The aim of the study was to assess the noise exposure and risk of noise-induced hearing loss (NIHL) among users of communication headsets (CHs) or headphones. Material and Methods Noise measurements and questionnaire surveys were carried out in 74 workers (aged: 31.8±7.3 years), including military aviation personnel (N = 12), transcribers (N = 18) and call center operators (N = 44). Sound pressure levels (SPLs) emitted by CHs (or headphones) were determined using the microphone in the real ear (MIRE) technique and artificial ear techniques according to PN-EN ISO 11904-1:2008 and CSA Z107.56-13, respectively. The risk of NIHL was evaluated in accordance with PN-ISO 1999:2000. Results The diffused-field-related A-weighted equivalent-continuous SPLs measured under CHs (or headphones) using the MIRE and artificial ear techniques reached values of 67–86 dB (10–90th percentile) and 68–89 dB (10–90th percentile), respectively. The study subjects used these devices 1.5–8 h (10–90th percentile) per day. Exposure to such noise levels for 40 years of employment causes the risk of hearing impairment (mean hearing threshold level for 2, 3 and 4 kHz > 25 dB) up to 10–12% (MIRE technique) or 19–22% (artificial ear technique). Individual daily noise exposure levels in study group varied 71–85 dB (10–90th percentile). A number of workers complained of problems with understanding speech in noisy environment (28.4%) and hearing whisper (16.2%) and experienced post-work temporary hearing symptoms (16.2–25.7%) as well. Conclusions The users of CHs and headphones should be included in the hearing conservation program. Further studies are also needed among employees of other industries. Med Pr. 2019;70(1):27–52

Opis:
Wstęp Celem pracy była analiza stanu słuchu pracowników zakładu meblarskiego z uwzględnieniem ich narażenia zawodowego na hałas i występowania dodatkowych czynników ryzyka uszkodzenia słuchu spowodowanego hałasem. Materiał i metody W grupie 50 mężczyzn w wieku 20–57 lat, zatrudnionych bezpośrednio przy produkcji mebli, przeprowadzono pomiary hałasu, badania kwestionariuszowe i ocenę stanu słuchu z zastosowaniem audiometrii tonalnej. Rzeczywiste progi słuchu pracowników porównano z progami przewidywanymi, wyznaczonymi według normy PN-ISO 1999:2000 na podstawie ich wieku, płci i narażenia na hałas. Wyniki Badane osoby pracowały przez 3–14 lat w warunkach narażenia na hałas o jego dziennym poziomie ekspozycji 82,7–94,8 dB (średnia: 90,9 dB). U wszystkich osób średni próg słuchu dla częstotliwości 500 Hz, 1000 Hz, 2000 Hz i 4000 Hz nie przekraczał 25 dB, ale w przypadku 11% audiogramów zaobserwowano załamki wysokoczęstotliwościowe, typowe dla działania hałasu. Rzeczywiste progi słuchu pracowników w zakresie częstotliwości 3000–6000 Hz były zbliżone do przewidywanych według PN-ISO 1999:2000. Stwierdzono istotnie statystyczne różnice między progami słuchu w podgrupach osób z wyższym (> 78 mm Hg) i niższym (≤ 78 mm Hg) ciśnieniem rozkurczowym krwi, palących papierosy i niepalących oraz pracujących bez kontaktu lub w kontakcie z rozpuszczalnikami organicznymi. U osób z ww. dodatkowymi czynnikami ryzyka obserwowano większe ubytki słuchu. Wnioski Wyniki badań potwierdzają, że podczas szacowania ryzyka uszkodzenia słuchu spowodowanego hałasem i opracowywania programów ochrony słuchu pracowników konieczne jest uwzględnianie dodatkowych (poza hałasem) czynników ryzyka, w tym palenia papierosów, podwyższonego ciśnienia tętniczego krwi i równoczesnej ekspozycji na rozpuszczalniki organiczne.

Background The aim of the study was to analyze the hearing status of employees of a furniture factory with respect to their exposure to noise and the presence of additional risk factors of noise-induced hearing loss (NIHL). Material and Methods Noise measurements, questionnaire survey and assessment of hearing, using pure tone audiometry, were carried out in 50 male workers, aged 20–57 years, directly employed in the manufacture of furniture. The actual workers’ hearing threshold levels (HTLs) were compared with the predictions calculated according to PN-ISO 1999:2000 based on age, gender and noise exposure. Results Workers under study were exposed to noise at daily noise exposure levels of 82.7–94.8 dB (mean: 90.9 dB) for a period of 3–14 years. In all subjects, mean HTL at 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz did not exceed 25 dB. Nevertheless, high frequency notches were found in 11% of audiograms. The actual workers’ HTLs at 3000–6000 Hz were similar to those predicted using PN-ISO 1999:2000. There were statistical significant differences between HTLs in subgroups of people with higher (> 78 mm Hg) and lower (≤ 78 mm Hg) diastolic blood pressure, smokers and non-smokers, and those working with organic solvents. Hearing loss was more evident in subjects affected by the additional risk factors specified above. Conclusions The results confirm the need to consider, in addition to noise, also some other NIHL risk factors, such as tobacco smoking, elevated blood pressure, and co-exposure to organic solvents when estimating the risk of NIHL and developing the hearing conservation programs for workers.

Opis:
Wstęp W przemyśle rozrywkowym hałas często osiąga wysokie poziomy ciśnienia akustycznego, jednak ryzyko uszkodzenia słuchu w tym sektorze nie zostało jeszcze dokładnie ocenione. Celem pracy była ocena związku między ekspozycją na wysoki poziom dźwięku a czasowym przesunięciem progu słuchu u osób pracujących na stanowisku barmana w lokalach rozrywkowych. Materiał i metody Badaniem objęto 18 barmanów (średni wiek: 25±7 lat) zatrudnionych w klubie muzycznym (N = 8), pubie (N = 5) i dyskotece (N = 5). Poziomy dźwięków oraz charakterystyka częstotliwościowa hałasu były określane za pomocą dozymetrii indywidualnej. Progi słuchu oceniano za pomocą audiometrii tonalnej przeprowadzanej przed rozpoczęciem dnia pracy oraz bezpośrednio (do 15 min) po jego zakończeniu. Badania słuchu przeprowadzono u barmanów w czasie 2 lub 3 sesji badawczych podczas pracy w weekendy. Uzyskano 92 audiogramy przed- i poekspozycyjne. Wyniki Uśrednione równoważne poziomy dźwięku odniesione do 8-godzinnego dnia pracy w ocenianych 3 lokalach muzycznych wynosiły 95 dBA, przekraczając ponad czterokrotnie dopuszczalne prawnie normy. U 77% badanych osób wykazano przynajmniej w 1 sesji pomiarowej czasowe przesunięcia progów słuchu ≥ 10 dB HL dla częstotliwości 4 kHz. Wnioski Osoby pracujące na stanowisku barmana stanowią grupę zawodową o podwyższonym ryzyku utraty słuchu. Niezbędne jest zwiększanie świadomości tego faktu oraz wdrażanie u tych pracowników programów ochrony słuchu, zgodnie z dyrektywą Komisji Europejskiej (EU 2003/10/WE). Med. Pr. 2019;70(1):17–25
Background Noise in entertainment industry often reaches high sound pressure levels. Nevertheless, the risk of hearing loss in this sector is insufficiently recognized. The aim of this study was the assessment of the relationship between noise exposure and temporary threshold shifts (TTS) for people working as bartenders at a variety of entertainment venues. Material and Methods The study comprised a total of 18 bartenders (mean age was 25±7 years old) employed at a music club (N = 8), pub (N = 5) and discotheque (N = 5). Personal dosimeters were used for determining noise levels and frequency characteristics. Hearing was evaluated by pre- (before work) and post-exposure (up to 15 min after the end of work) pure tone audiometry. Hearing tests were carried out for bartenders during 2 or 3 sessions while working on weekends. Results The mean personal noise exposure level normalized to a nominal 8-hour working day was 95 dBA, above 4 times higher than the accepted legal limit. The TTS values (10 dB HL or more) were significant at 4 kHz for both ears for 77% of bartenders. Conclusions People working as bartenders represent a professional group with an increased risk of hearing loss. Raising awareness of this fact and implementing hearing protection programs in this group of workers is urgently needed, in line with the European Commission Directive (EU Directive 2003/10/EC).
