Sound level

Sound level refers to various logarithmic measurements of audible vibrations and may refer to:


 * 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
