Decibels via Loudness--Distance Properties of a Loudspeaker
Bates, Alan
Physics Teacher, v52 n5 p302-303 May 2014
Loudness, or sound intensity level, is a human perceived or subjective measurement with units, decibels, based on the response of the human ear to different sound intensities. The response of the human ear at fixed frequency is close to being logarithmic. The experiment reported here investigates the relationship between measured sound intensity level, or loudness, and distance from a sound source such as a loudspeaker.
