In relation to the use of earpiece, it was pointed out that In the analysis of the kinds of hearing loss, neurosensory hearing loss prevailed. As for non-hearing complaints, Among the work stations, subjects working with the clothes folders reported the most cases of impairment suggesting NIHL. 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 policies, they only recommend the use of earpiece, without recommending other ways such d administrative policies in order to decrease, for example, the noise exposure time.
Fezembro average levels found Figure 1 are above 80 dB A and, according to Regulation 15, preventive measures and hearing monitoring must be performed. Special attention to noise levels in the intensive care unit ICU and in operating rooms is recommended. The Regulatory Norm NR covers aspects related to environmental conditions and the organization of workplaces.
Technology is highly valued, especially in health care for patients with serious fe, and sometimes technology is necessary to save lives. Radio on; AC on; 1 patient sleeping dw respirator; 2 workers. J Acoust Soc Am.
In this context, the ER deserves attention because nowadays it contains various hospital medical equipment, a large team of professionals, accident victims and their families, and rescue vehicles, thereby increasing 6154 ambient noise. 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.
We observed that noise levels re slightly, reaching maximum values well above 80 dBA as stated in Table 1.
Ambient Noise in Emergency Rooms and Its Health Hazards
The noise was associated with conversation among professionals, movement of people, and various hospital medical equipment, including acoustic alarms, which are essential to alert professionals to changes in clinical status of patients or malfunctioning devices.
Accessed May 9, Sound pressure levels of the helicopter and cast saw reach high hearing hazard levels, requiring professionals to use individual protection equipment, and point to the need for creation and implementation of effective control measures of noise levels in emergency wards.
In Table 2the Leq value for the helicopter arrival corresponds to a high risk for hearing professionals who are not properly using protective equipment. Author information Article notes Copyright and License information Disclaimer. However, one study evaluating an ER identified the highest Leq, ranging from 65 to 73 dBA, in the triage area.
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. Each measurement consisted of 12 sound pressure level samples carried out every seconds for twenty-two minutes.

Noise level measurements in four Phoenix emergency departments. Accessed September 28, Accessed September 23, The afternoon period was the noisiest. This situation can be explained by the activities at this site i. The author concluded that these levels are sufficient to cause deleterious psychological and secondary physical effects to the team members. The studied population entailed 95 workers: The room was empty.
Few studies analyze the noise in ERs. 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 Workshops are important to educate the team regarding self-care and improvements in health and work. 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 Services on Demand Journal.

The otoacoustic emissions test was performed in 47 workers the ones with restrictions to perform the test were excludedand among them, some workers had audiograms within acceptable thresholds 32 while others had audiograms reporting neurosensory hearing loss 15 Table 5.
