How do I know if my hearing is at risk?
According to the Centers for Disease Control and Prevention, exposure to sounds 85 decibels (dB) and above can damage your hearing.
The louder or higher decibel the sound is, the less exposure time is required for hearing loss to occur.
This chart shows examples of sounds with decibel levels ranging from 40 dB to 140 dB, and the amount of exposure time necessary to put your hearing at risk.
