Regulations regarding risk from exposure to noise at work entail action at levels of 85 dB(A) and above. At 80 dB(A) there is no material risk in the vast majority of individuals.At 90 dB(A) and above the risk becomes material, with the majority of individuals accruing a significant hearing impairment.

How much decibel can human ear hear?
Humans have a hearing threshold of around 0 decibels. Above this threshold, sounds with higher sound pressure levels are heard as louder noises. Sounds above 90 dB can lead to chronic hearing damage if people are exposed to them every day or all the time.
How long can you listen to 90?
OSHA PEL reccomends:The maximum exposure time for unprotected ears per day is 8 hours at 90 dB , A-weighted, slow response For every 5- dB increase in volume, the maximum exposure time is cut in half. Many hearing professionals believe that these permissible levels are still too high for hearing safety.
How many times is 80 dB louder than 50?
When it comes to 80 decibels, the difference in intensity is even higher. If 70 decibels is 100 times more intense than 50 decibels, 80 decibels is 1000 times more intense. And you will perceive an 80-decibel sound 8 times as loud.

Decibel Level?
Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.
Is 84 dB loud?
Every day we hear a variety of sounds. Sounds that are too loud or loud sounds over a long time, can damage your hearing. The loudness of sounds is measured in decibels (dB).

| 70-90 dB | Recreational vehicle |
| 88 dB | Subway, motorcycle |
| 85-90 dB | Lawnmower |
How long can you listen to 85 dB?
8 hours
Sounds over 85 dBa can damage your hearing faster. The safe listening time is cut in half for every 3-dB rise in noise levels over 85 dBA. For example, you can listen to sounds at 85 dBA for up to 8 hours. If the sound goes up to 88 dBA, it is safe to listen to those same sounds for 4 hours.
How loud is 77 decibels?
| Noise Source | Decibel Level |
|---|---|
| Passenger car at 65 mph at 25 ft (77 dB); freeway at 50 ft from pavement edge 10 a.m. (76 dB). Living room music (76 dB); radio or TV-audio, vacuum cleaner (70 dB). | 70 |
| Conversation in restaurant, office, background music, Air conditioning unit at 100 ft | 60 |
How much louder is 95 dB than 85 dB?
Because the decibel scale is logarithmic, every 10 decibels you add multiplies the intensity of the sound 10 times. This means that 95 decibels is 10 times louder than 85 decibels and 100 times louder than a 75 decibel sound. Therefore, don’t take any noise level above 85 dB lightly.
