Even with the implementation of Environmental Risk Prevention Programs, in both companies, it was not verified references on implementation of collective noise control policies, and as for the implementation of individual protection re, they only recommend the use of earpiece, without recommending other ways such as administrative policies in order to decrease, for example, the noise exposure time.

Audiograms were classified under Regulation N. Author information Article notes Copyright and License information Disclaimer. Universidade Estadual Paulista; dezembdo In the analysis of the relationship between audiometric result impaired or normal – considering the worse ear — and age group, findings are displayed in Table 3. However, many workers have their exams overdue.

Accessed September 23, Similar results were found in other studies in the hospital laundry, evidencing a environmental hostility to hearing 79 Kei the first step of the research, a documental analisys from the Medical Control and Occupational Health Program and the Environmental Risk Prevention Program was carried out, proposed by the regulations of Health and Safety at Work Regulation n.

It is pointed out that noise level reported in that work station 19777 not above the tolerance threshold of 84 dB A. A total of 95 noise-exposed workers, participated in the study As for stimulus, nonlinear broadband ticks were used, 80dB SPL intensity.

Although there is variation from individual to individual, people are directed to avoid exposure to noise levels dezmbro exceed 85 to 90 sound pressure level ambiance [dBA]. The room was empty. All subjects who participated in the study signed the Free Informed Consent Form.


As for the work time length in the laundry, Accessed August 05, Tinnitus was reported by In relation to the use of earpiece, it was pointed out that The implementation of program promoting health dezembdo prevention is recommended.

Results from the analyzed scientific publications suggest that the use of OAE in occupational health has been valuable instrument dezembrl investigation and early diagnosis of NIHL 31 Rev da Soc Bras de Fonoaudiologl. Ninety-five 95 workers, who participated in the study, underwent audiological testing at a Teaching Clinic in Curitiba.

Special attention to noise levels in the intensive care unit ICU and in operating rooms is recommended. After going through all the selected locations, the evaluation was done three more times, so that four measurements were taken at each site, with maximum, minimum, and Leq, in the mornings between 7 am and 1 pmin the afternoon between 1 pm and 7 pmand at night between 7 pm and 7 am.

Normal hearing thresholds were found in In the present study, the highest Leq occurred in the ALS anteroom. The average levels found Figure 1 are above 80 dB A and, according to Regulation 15, preventive measures and hearing monitoring must be performed. The lowest Lmin was detected in the suture room Main corridor Morning Rev Bras Otorrinolaringol Engl Ed ; 69 6: Even taking NIHL risk, it was evidenced that In relation to the Medical Control and Occupational Health Program, in dezenbro document of the outsourced company, it was mentioned re noise risk and recommended yearly audiometric exam to all employees.

Table 2 presents the levels of continuous Leq dBA noise found in various equipment operating in the ER. Conclusion In all assessed points, noise levels were above the comfort levels recommended by the Brazilian Association of Technical Standardswhich may harm users’ and professionals’ health as well as influence professional performance in the emergency ward.


Of the various noise sites evaluated Table 1the lowest Leq was measured in the suture room Regarding symptoms and complaints reported by the workers Table 1which can be consequential to occupational noise exposure, it was verified tiredness, stress, irritability, headache, depression, concentration difficulties, stomachache, among others.

Pei for Community Noise Noise sources and their measurement. In the document of the Environmental Risk Prevention Program, elaborated and organized by the Specialized Service in Safety Engineering, there are references to noise rates only in the clean laundry area, more specifically, in the work stations: AC, air conditioner; Leq, average equivalent level; dBA, compensated for on the A-weighted decibel scale.

Audiological results match results found in the literature 28 Audiometric exams are held at a specialized clinic, not related to the company.

These findings match literature data where TrOAES can verify the impairment degree of the outer hair cells in noise-exposed individuals even if Threshold Tonal Audiometry has not yet detected evident disorders However, in the present study, besides the audiometries carried out in the laundry workers in order to identify noise-induced hearing loss, the otoacoustic emissions test was held as it can identify cochlear changes even before they are detected by audiograms, thus contributing to the early diagnosis in occupational health Open in a separate window.
