The above is inacacurate to the extreme. Typically noise is measured in terms of the sound pressure above or below a particular reference point. SPL or sound pressure level is computed as: dB=20 X log of pressure measured over .0002dynes per CM squared. It is a logarithmic scale. SPL is the standard for specifying sound level. —Preceding unsigned comment added by 24.197.246.79 (talk • contribs)
