The acoustic power of a sound source, expressed in watts. [Hirschorn, Martin ; Compendium of Noise Engineering - Part I Sound & Vibration Magazine, July 1987. Sound & Vibration Magazine, July 1987.]

Sound Power Level (Lw)
Acoustics The acoustic power radiated from a given sound source as related to a reference power level (typically 10-12 watts) and expressed in decibels as:

Lw=10 log(W/10-12) dB or
Lw=10 log W+120 dB

where W = acoustic power in watts. By definition, one watt therefore corresponds to 120 dB for Lw.
