What Are Safe Sound Levels? - Hearing Loss Help

In the past, it was considered that 90 dB was the safe limit for an 8-hour day’s exposure to sound. Then they cut the time in half for every 5 dB above that level. The problem is that sound levels double for each 3 dB increase, so this wasn’t accurate in the first place. It looked good on paper, and was easy to calculate, but it did not reflect reality.

The National Institute of Occupational Safety (NIOSH) states that for a 115 decibel (dB) sound, the exposure limit is just 28 seconds. Exposure to noise louder than the Environmental Protection Agency (EPA) safe noise level of 70 dB over 24 hours will damage hearing. Measurement

Meanwhile, guidelines and rationales differ regarding safe listening levels: Debate continues over the exact point that noise levels threaten hearing, with some pegging it as high as 85 dB and others as low as 70 dB. There’s also no consensus on when exposure at various levels can result in noise-induced hearing loss (NIHL).
What Is a Safe Noise Level for the Public?
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5308171/
The EPA calculated the safe noise level for the public to prevent hearing loss to be a 70-decibel time-weighted average for a 24-hour period (L eq(24) = 70).3 (The decibel scale is logarithmic, so 85-decibel sound has 31.6 times more energy than 70-decibel sound, not 21% more, as might be commonly thought.) The EPA did not adjust for lifetime noise exposure, now almost 80 years …

For reference, exposure to sound levels above 85 dB (equal to a lawnmower or leaf blower) can cause possible ear damage with exposure of more than two hours, while exposure to sound of 105 to 110 dB can cause damage in five minutes. Sound less than 70 dB is unlikely to cause any significant damage to the ears.
Occupational Noise Exposure - Overview | Occupational ...

With noise, OSHA's permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day. The OSHA standard uses a 5 dBA exchange rate. This means that when the noise level is increased by 5 dBA, the amount of time a person can be exposed to a certain noise level to receive the same dose is cut in half.

Eighty-five decibels is considered the highest safe exposure level up to a maximum of eight hours. The permissible time for safe listening decreases as sound levels increase. For example, a sound as high as 100 dB – the level produced by a subway train – can be safely listened to for only 15 minutes each day.

A better indicator of safe sound levels comes from NIOSH (National Institute for Occupational Safety and Health). NIOSH has recommended limits that are well rooted in audiological data concerning hearing loss . The takeaway: If our question is whether levels are legal, we turn to OSHA. If our question is whether levels are safe, we look to NIOSH. Smaart …
