    Opis:
    Joseph Ratzinger, chosen for the See of Peter 19 April 2005, after three years of papal ministry, may be, in my opinion, considered a worthy continuator of John Paul’s II mission, the latter described as the Human Rights Pope due to his activities in the field. The main goal of this essay is to analyze Benedict XVI’s most characteristic practices and texts, which directly refer to the issue of human rights, especially in the context of respect for and protection of human rights. The next aim is to show the contexts in which John Paul II’s great friend invokes or refers to the legacy of his eminent predecessor and to demonstrate the differences between John Paul II and Benedict XVI’s perception of the significance of human rights in the lives of contemporary societies.

    Opis:
    Background It has been shown that musicians are at risk of noise-induced hearing loss. The aim of the study has been to evaluate the temporary changes of hearing in the case of orchestral musicians after group rehearsals. Material and Methods The study group comprised 18 orchestral musicians, aged 30–58 years old (mean: 40 years old) having 12–40 years (mean: 22 years) of professional experience. The temporary changes in hearing after group rehearsals were determined using transient-evoked otoacoustic emissions (TEOAEs). Noise exposures during group rehearsals were also evaluated. Results Musicians’ hearing threshold levels were higher (worse) than expected for the equivalent non-noise-exposed population. Moreover, the high frequency notched audiograms were observed in some of them. After rehearsals, during which musicians were exposed to orchestral noise at A-weighted equivalent-continuous sound pressure level (normalized to 8-h working day) varied from 75.6–83.1 dB (mean: 79.4 dB). The significant post-exposure reductions of TEOAE amplitudes (approx. 0.7 dB) both for the total response and frequency bands of 2000 and 3000 Hz were noted. However, there were no significant differences between pre- and postexposure reproducibility of TEOAE. Conclusions Obtained results have confirmed that orchestral musicians are at risk of hearing loss due to their professional activities, even at exposures to orchestral noise less than the limit values for occupational noise.

    Wstęp Wykazano, że muzycy narażeni są na ryzyko utraty słuchu wywołanej hałasem. Celem pracy była ocena czasowych zmian słuchu u muzyków orkiestrowych po udziale w próbach zespołowych. Materiał i metody Badana grupa składała się z 18 muzyków orkiestrowych w wieku 20–58 lat (średnia: 40 lat) o stażu zawodowym 12–40 lat (średnia: 22 lata). Czasowe zmiany słuchu po próbach zespołowych wyznaczono na podstawie wyników badań emisji otoakustycznych przejściowych (transient-evoked otoacoustic emissions – TEOAE). Oceniono również poziom ekspozycji na hałas podczas prób zespołowych. Wyniki Próg słuchu muzyków był wyższy (gorszy) niż oczekiwany w równoważnej populacji nienarażonej na hałas. Ponadto w audiogramach części muzyków zaobserwowano „załamki” typowe dla działania hałasu wysokoczęstotliwościowe. Po próbach zespołowych, podczas których muzycy byli narażeni na hałas orkiestrowy o poziomie ekspozycji na hałas odniesiony do 8-godzinnego dnia pracy (skorygowany charakterystyką częstotliwościową A) o wartościach 75,6–83,1 dB (średnia: 79,4 dB), zaobserwowano statystycznie istotne obniżenie amplitudy TEOAE (ok. 0,7 dB), zarówno w przypadku zbiorczej odpowiedzi, jak i w pasmach 2000 i 3000 Hz. Nie stwierdzono jednak istotnych różnic między wynikami powtarzalności TEOAE przed ekspozycją i po ekspozycji. Wnioski Uzyskane wyniki potwierdzają, że praca muzyków orkiestrowych wiąże się z ryzykiem uszkodzenia słuchu, nawet przy ekspozycji na hałas orkiestrowy nieprzekraczającej wartości dopuszczalnych dla hałasu w miejscu pracy.

    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

    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.

    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.

    Opis:
    Objectives: The overall aim of this study was to evaluate the perception of and annoyance due to the noise from wind turbines in populated areas of Poland. Material and Methods: The study group comprised 156 subjects. All subjects were asked to fill in a questionnaire developed to enable evaluation of their living conditions, including prevalence of annoyance due to the noise from wind turbines and the self-assessment of physical health and well-being. In addition, current mental health status of the respondents was assessed using Goldberg General Health Questionnaire GHQ-12. For areas where the respondents lived, A-weighted sound pressure levels (SPLs) were calculated as the sum of the contributions from the wind power plants in the specific area. Results: It has been shown that the wind turbine noise at the calculated A-weighted SPL of 30-48 dB was noticed outdoors by 60.3% of the respondents. This noise was perceived as annoying outdoors by 33.3% of the respondents, while indoors by 20.5% of them. The odds ratio of being annoyed outdoors by the wind turbine noise increased along with increasing SPLs (OR = 2.1; 95% CI: 1.22-3.62). The subjects' attitude to wind turbines in general and sensitivity to landscape littering was found to have significant impact on the perceived annoyance. About 63% of variance in outdoors annoyance assessment might be explained by the noise level, general attitude to wind turbines and sensitivity to landscape littering. Conclusions: Before firm conclusions can be drawn further studies are needed, including a larger number of respondents with different living environments (i.e., dissimilar terrain, different urbanization and road traffic intensity).

    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.

    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

Nie stwierdzono przekroczenia tła geochemicznego zawartości Mn w osadach dennych rzeki Ełk. Największa ilość Mn związana była z najdrobniejszą frakcją, najmniejsza zaś z frakcją najgrubszą. Największą zawartość badanego pierwiastka zaobserwowano w punkcie Ełk Barany, co związane jest z rozwijającym się przemysłem na terenie miasta Ełk. Wszystkie z badanych makrofitów wykazały zawartości Mn znacznie większe od ilości naturalnie występujących w roślinach. Najwięcej Mn związane było z korzeniami roślin, a najmniej z liśćmi. Największa zawartość Mn została zanotowana w przypadku Nuphar lutea, a najmniejsza – Typha latifolia.
