NOISE and YOUR JOB
... Noise levels are measured in decibels (dBA) • A small increase in decibels equates to a large increase in noise (logarithmic) • An increase of just 3 dB doubles the amount of sound 88 dB can do twice as much harm to your ears as 85 dB. An increase of 10 dB means it is ...

Earplug
An earplug is a device that is meant to be inserted in the ear canal to protect the user's ears from loud noises or the intrusion of water, foreign bodies, dust or excessive wind.
