Sound exposure level, measure of the sound exposure of a sound relative to a reference value Sound power level, measure of the rate at which sound energy is emitted, reflected, transmitted or received, per unit time Sound pressure level, measure of the effective pressure of a sound relative to a reference value Sound intensity level, measure of the intensity of a sound relative to a reference value Sound velocity level, measure of the effective particle velocity of a sound relative to a reference value
