It is helpful when discussing sound volume to understand how volume or loudness is measured. The term decibel is the scientific measurement for determining the loudness and softness of sound. Below are a few measurements I pulled from the Galen Carol Audio web site (I believe these are dB A scale measurements). You can see the complete list here.
