Decibels or dB is the unit used to measure sound. The human ear has an approximately logarithmic response to sound over a very large dynamic range – typically from 0.00002 to 200 Newtons per square metre (N/m2). Decibels provide a logarithmic scale to describe sound pressure and sound power levels. The threshold of hearing for most people corresponds to a sound pressure level of 0 dB and the threshold of aural pain to a sound pressure level of 140 dB.
