As with sound pressure, sound power level is often quantified in decibels and is given by the equation: Sound Power Level=10log 10 (p⁄pref ) dB Where P is the sound power and P ref is the universally agreed upon reference sound power, 1 pW. However, often nowadays sound power level is given in bels (1 bel = 10 decibels) so as not to confuse with sound …
