Opis:
Ocenę narażenia na hałas nauczycieli w szkołach podstawowych przeprowadzono na podstawie badań ankietowych, pomiarów hałasu na stanowiskach pracy nauczycieli oraz analizy danych statystycznych o zagrożeniach i chorobach zawodowych w sektorze edukacji. Badania wykazały, że hałas stanowi główny czynnik uciążliwy w środowisku szkolnym. Hałas w szkołach może być również czynnikiem szkodliwym. Wysokie poziomy hałasu rzędu 80-85 dB mierzone w korytarzach podczas przerw i w salach gimnastycznych mogą powodować ryzyko uszkodzenia słuchu uczniów i nauczycieli.
Assessment of teachers' exposure to noise in primary schools was carried out on the basis of questionnaire studies, noise measurements at teachers' workplaces and an analysis of statistical data on hazards and occupational diseases in the education sector. The studies showed that noise is the main factor of annoyance in the school environment. Noise in schools is also a harmful factor. High noise levels of 80 - 85 dB, measured in corridors during breaks and in gyms, can cause the risk of hearing damage among teachers and students.

This article presents examples of the use of modern technologies in order to identify, counteract and limit industrial hazards. The article focuses on the possibility of using computational methods to shape the work environment and to design effective means of noise reduction. The issue of whether acoustical maps of industrial establishments are useful for the purposes of analyzing men's exposure to noise in excess of norm-defined standards, as well as the idea of creating a new indicator to assess noise hazard in the environment, have both been elaborated. The article covers basic examples of research being conducted by Creation of Systems for Reduction of Industrial Hazards Team working for the Institute of Production Engineering of Faculty of Organization and Management of Silesian University of Technology.

Opis:
The intensive development of sport shooting and the significant increase in the number of people using sport and recreational shooting ranges also increases the risk of hearing damage to shooters, due to exposure to impulse noise from the shots of firearms. This article discusses the methodology for assessing shooters’ exposure to noise and identifies and extensively discusses possible ways to minimise this exposure. It then describes a research experiment carried out to measure and calculate the effectiveness of noise reduction by means of acoustic silencers when shooting with typical weapons in the most popular sporting and hunting calibres. The experiment also included firing tests with subsonic ammunition. On this basis, conclusions were drawn regarding the possibility of reducing impulse noise during shooting and the possibility of eliminating the risk of hearing damage.

Opis:
Warning signals generated by sirens of authorized emergency vehicles should be audible and recognizable to all road users. Currently, there is no legislation in Poland defining sound pressure levels (SPLs) of audible warning signals generated by sirens of authorized emergency vehicles. Measured A-weighted SPLs of those signals range between 104 and 108 dB. While for road users, an audible warning signal is a source of important information and its A-weighted SPL is acceptable, it may be a source of annoying noise to an emergency vehicle crew. That is why, it is necessary to find a method of improving the acoustic comfort of the crew and, at the same time, maintaining the informational function of audible warning signals.

Opis:
W warunkach przemysłowych na niestacjonarnych stanowiskach pracy narażenie na hałas zmienia się w cyklu rocznym i dlatego standardowe metody oceny narażenia (odniesienie do dnia lub tygodnia) nie pozwalają oszacować ryzyka zawodowego. W artykule podjęto próbę oszacowania ryzyka zawodowego narażenia na hałas słyszalny i infradźwiękowy w odniesieniu do roku, na przykładzie pracownika remontowego w elektrowni węglowej.
Exposure to noise in non-stationary workstations in industrial conditions has an annual cycle of changes. That is why standard methods of assessing exposure (in relation to a day or a week) are not appropriate for estimating occupational risk. The article makes an attempt as estimating occupational risk resulting from audible end infrasound noise in relation to a year, using a maintenance worker in a real power plant as an example.

W artykule przedstawiono ocenę drgań mechanicznych i hałasu działających na kierowców różnych pojazdów drogowych. Oceny dokonano na podstawie wyników przeprowadzonych badań terenowych. Badania na wybranych stanowiskach pracy wykazały porównywalne narażenia pochodzące od drgań działających przez kończyny górne i od drgań działających w sposób ogólny. W większości przypadków zarejestrowane poziomy hałasu były poniżej wartości dopuszczalnej (NDN). Mimo że drgania jak i hałas nie przekraczały wartości dopuszczalnych, pracownicy uskarżali się na dolegliwości związane z działaniem czynników wibroakustycznych. Metody oceny podane w odpowiednich normach nie pozwalają przy określaniu ryzyka zawodowego na uwzględnienie łącznego oddziaływania drgań i hałasu występujących jednocześnie.
This article presents an evaluation of mechanical vibration and noise that affect drivers of various road vehicles. This evaluation has been developed on the basis of the results of field investigations. Studies at selected workstations showed that hazards caused by hand-arm and whole-body vibration were comparable. In most cases noise was under the limit value (maximum admissible intensity of an agent harmful to health in the working environment). Although vibration or noise did not exceed limit values, workers complained of diseases related to vibroacoustic agents. Standard methods do not make it possible to evaluate the risk of vibration and noise diseases caused by the combined influence of vibrations and noise which exist simultaneously.

Opis:
This study aimed to assess exposure to sound and the risk of noise-induced hearing loss (NIHL) in orchestral musicians. Sound pressure level was measured in 1 opera and 3 symphony orchestras; questionnaires were filled in. On the basis of that data, the risk of NIHL was assessed according to Standard No. ISO 1999:1990. Classical orchestral musicians are usually exposed to sound at equivalent continuous A-weighted sound pressure levels of 81−90 dB (10th−90th percentiles), for 20−45 h (10th−90th percentiles) per week. Occupational exposure to such sound levels over 40 years of employment might cause hearing loss (expressed as a mean hearing threshold level at 2, 3, 4 kHz exceeding 35 dB) of up to 26%. Playing the horn, trumpet, tuba and percussion carries the highest risk (over 20%).

Pure-tone audiometry (PTA) and transient-evoked otoacoustic emissions (TEOAEs) were determined in 57 classical orchestral musicians along with a questionnaire inquiry using a modified Amsterdam Inventory for Auditory Disability and Handicap ((m)AIADH). Data on musicians’ working experience and sound pressure levels produced by various groups of instruments were also collected. Measured hearing threshold levels (HTLs) were compared with the theoretical predictions calculated according to ISO 1999:1990. High frequency notched audiograms typical for noise-induced hearing loss were found in 28% of the subjects. PTA and TEOAE consistently showed a tendency toward better hearing in females vs. males, younger vs. older subjects, and lower- vs. higher-exposed to orchestral noise subjects. Audiometric HTLs were better than theoretical predictions in the frequency range of 2000–4000 Hz. The (m)AIADH scores indicated some hearing difficulties in relation to intelligibility in noisy environment in 26% of the players. Our results indicated a need to implement a hearing conservation program for this professional group.

Opis:
The overall purpose of this study was to assess hearing status in professional orchestral musicians. Standard pure-tone audiometry (PTA) and transient-evoked otoacoustic emissions (TEOAEs) were per- formed in 126 orchestral musicians. Occupational and non-occupational risk factors for noise-induced hearing loss (NIHL) were identified in questionnaire inquiry. Data on sound pressure levels produced by various groups of instruments were also collected and analyzed. Measured hearing threshold levels (HTLs) were compared with the theoretical predictions calculated according to ISO 1999 (1990). Musicians were exposed to excessive sound at weekly noise exposure levels of for 81-100 dB (mean: 86.6±4.0 dB) for 5-48 years (mean: 24.0±10.7 years). Most of them (95%) had hearing corresponds to grade 0 of hearing impairment (mean hearing threshold level at 500, 1000, 2000 and 4000 Hz lower than 25 dB). However, high frequency notched audiograms typical for noise-induced hearing loss were found in 35% of cases. Simultaneously, about 35% of audiograms showed typical for NIHL high frequency notches (mainly occurring at 6000 Hz). When analyzing the impact of age, gender and noise exposure on hearing test results both PTA and TEOAE consistently showed better hearing in females vs. males, younger vs. older musicians. But higher exposure to orchestral noise was not associated with poorer hearing tests results. The musician’s audiometric hearing threshold levels were poorer than equivalent non-noise-exposed population and better (at 3000 and 4000 Hz) than expected for noise-exposed population according to ISO 1999 (1990). Thus, music impairs hearing of orchestral musicians, but less than expected from noise exposure.

Opis:
Noise measurements and questionnaire inquiries were carried out for 124 workers of a rolling stock plant to develop a hearing conservation program. On the basis of that data, the risk of noise-induced hearing loss (NIHL) was evaluated. Additionally, the workers’ hearing ability was assessed with the (modified) Amsterdam inventory for auditory disability and handicap, (m)AIADH. The workers had been exposed to noise at A-weighted daily noise exposure levels of 74–110 dB for 1-40 years. Almost one third of the workers complained of hearing impairment and the (m)AIADH results showed some hearing difficulties in over half of them. The estimated risk of hearing loss over 25 dB in the frequency range of 3-6 kHz was 41–50% when the standard method of predicting NIHL specified in Standard No. ISO 1999:1990 was used. This risk increased to 50-67% when noise impulsiveness, coexposure to organic solvents, elevated blood pressure and smoking were included in calculations.

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.

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

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.
