Noise levels are measured in decibels (dB), exposure
to any noise at or above 85 dB can cause gradual
hearing loss.
Monitor your use; hearing loss is a function of
loudness versus time. The louder it is, the less
time you can be exposed to it. The softer it is, the
more time you can listen to it.
This decibel (dB) table compares some common
sounds and shows how they rank in potential
harm to hearing.
