What decibel level is considered hazardous noise?
The NIOSH REL for noise is 85 decibels, using the A-weighting frequency response (often written as dBA) over an 8-hour average, usually referred to as Time-Weighted Average (TWA). Exposures at or above this level are considered hazardous. OSHA sets legal limits on noise exposure in the workplace. These limits are based on a worker’s time ...
At what dB does OSHA require hearing protection?

At what volume is hearing protection required?
85 decibelsStandards. OSHA requires employers to implement a hearing conservation program when noise exposure is at or above 85 decibels averaged over 8 working hours, or an 8-hour time-weighted average (TWA).
What level of decibels triggers the need for hearing protection?
A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.

Why is hearing loss prevention important?
Your hearing is an important asset. Once it is lost or damaged, there is very little you can do to get it back. This is why hearing loss prevention, through PPE, administrative and engineered controls, is so vital. To ensure your safety, it is important to learn about the decibel level protection guidelines and schedule an audiometry test.
Should an employer determine noise levels?

What makes a loud noise in the workplace?
In the workplace, these types of sudden loud noises often come from machine presses that are used to shape metal or other objects. This type of extreme noise hazard can easily surpass 120 dB—the louder the noise is, the more damaging it will be. However, as with all noise pollution, proximity to the noise determines how loud it will be. Any facility that has machines or other objects that cause sudden loud noises will need to make sure there are signs nearby reminding employees of PPE requirements.
