Decibels

I found the following, understandable definition:

"Named after Alexander Graham Bell. We perceive differences in volume level in a logarithmic manner. Our ears become less sensitive to sound as its intensity increases. Decibels are a logarithmic scale of relative loudness. A difference of about 1 dB is the minimum perceptible change in volume, 3 dB is a moderate change in volume, and about 10 dB is an apparent doubling of volume. 0 dB is the threshold of hearing and 130 dB is the threshold of pain."

Decibels	Degree	Comparable Loudness or Feeling
140	Deafening	Jet Aircraft, Artillery fire
130	Deafening	Threshold of Pain, Causes Immediate Ear Damage
120	Extremely Loud	Thunder or Diesel Engine Room
110	Extremely Loud	Close to a train
100	Very Loud	Wood Saw, Home Lawn Mower, car horn@16’

Over 90 decibels - Hearing can be damaged if protective equipment is not worn

Decibels	Degree	Comparable Loudness or Feeling
90	Very Loud	Symphony, Truck without Muffler
80	Loud	Car Noise at high speed, Police whistle, motorboat on plane
