Preventing Hearing Damage When Listening With Headphones
... As seen in the OSHA Noise Exposure table in figure 2, the louder the sound, the less time it takes for damage to occur. OSHA limits noise exposure levels in the work environment to about 90dB for an 8-hour period, but permits exposure to higher levels for short periods. Many experts believe that the ...
