Sound level
# 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
