Ambient Noise in Emergency Rooms and Its Health Hazards

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. By analyzing the Environmental Risk Prevention Program and the Medical Control and Occupational Health Program, it was observed that they were organized only by the outsourced firms 19777 the Specialized Service in Safety Engineering and Occupational Medicine, responsible for the workers hired by the hospital.

Main corridor Morning Journal List Xe Arch Otorhinolaryngol v. Ten indoor points in the emergency ward were assessed; the helicopter as well as several available pieces of equipment in the ward were assessed individually.

The steps followed a ds, with a 2- minute, second evaluation at each site. Therefore, this Norm recommends that the equivalent sound pressure level Leq not exceed 35 A-weighted decibel scale dBA in rooms where patients are treated and observed. As for non-hearing complaints, AC, air conditioner; Leq, average equivalent level; dBA, compensated for on the A-weighted decibel scale.

Ninety-five 95 workers, who participated in the study, underwent audiological testing at a Teaching Clinic in Curitiba. Conclusion the laundry is a hazardous place for hearing loss, thus preventive measures, such as Hearing Conservation Programs must be adopted.

Noise effects on hospital laundry workers? hearing

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 6541 detected by audiograms, thus contributing to the early diagnosis in occupational health Formerly, however, some female workers performed tasks in other laundry stations where reported noise levels were above 85 dB Asuch as the clothes washing area Literature mentions that it is a common symptom for those who work in noisy settings such as laundries 23 Among the work stations, subjects working with the clothes folders reported the most cases of impairment suggesting NIHL.


Few studies analyze the noise in ERs.

The environment of the ER does not have a certain time of increased noise due to several activities that happen according to the demand of the moment. Therefore, it appears that the noise levels present in the ER can impact the overall health of the population. The recommendation for hospital areas is that the noise level should not exceed 55 dB.

For the helicopter and dezembr, a single measurement was performed in the afternoon. The author concluded that these levels are sufficient to cause deleterious psychological and secondary physical effects to the team members. Normal hearing thresholds were found in The study evaluated the comfort levels of workers in a hospital ward, as determined by NR, and found that the values were 50 dBA, 51 dBA, and 56 dBA in each ward, 22 which were lower than those detected in the ER.

The Regulatory Norm NR covers aspects related to environmental conditions deezembro the organization of workplaces.

Received May 12; Accepted Jun 1. Even taking NIHL risk, it was 9177 that Cases presenting earwax, even partial earwax were also excluded, taking up a sample of 47 assessed workers.

Leq levels of helicopter and cast saw entail high hearing hazard, requiring professionals to use individual protection equipment, and point to the need of creation and implementation of effective control measures of noise levels in emergency wards.

It is necessary to implement effective measures to control noise in the ER, as well as providing for the satisfactory use of ear protection equipment for employees exposed to noise.

As for the professional background on noise exposure, Documental laundry analysis was carried out Medical Control and Occupational Health Program and Environmental Risk Prevention Programnoise measurement, anamnesis-applied hearing evaluation, tonal threshold audiometry, acoustic immittance, and transient otoacoustic emission testing.


Rev Bras Otorrinolaringol Engl Ed ; 73 2: The afternoon period was the noisiest. Rest period from occupational noise was 14 working hours, that is, the audiological testing was held before the working hours in the hospital laundry objectifying to exclude any temporary hearing loss. The helicopter at dBA and the cast saw at 90 dBA were the noisiest equipment, and the lowest noise level found was the activated oximeter at Laundry workers were invited to participate in the research and informed about its objective.

Noise in the adult emergency department of Johns Hopkins Hospital. Accessed August 10, As for stimulus, nonlinear broadband ticks were used, 80dB SPL intensity. Noise levels in a general surgical ward: In relation to the use of earpiece, it was pointed out that And, in another study carried out in the laundry of the Clinicas Hospital from the medical school of Universidade Federal de Goias UFG with 86 workers exposed to high noise levels, Published online Aug In relation to work time length, it was verified that Accident victims arrive in this area, and it is also a meeting place for various professional teams that send and receive patients, causing movement of people and equipment and the need for oral communication, which increases sound pressure level.

Author information Article notes Copyright and License information Disclaimer. In the present study, The implementation of program promoting health and prevention is recommended. Thus, it is fundamental to carry out not only audiometric exams for hearing monitoring, but also the implementation of a Hearing Conservation Program for laundry workers.
