| Definition |
The pressure caused by a sound wave and expressed as the logarithm of the effective sound pressure to a reference value; also called acoustic pressure level. Unless otherwise specified, pressure is expressed in root-mean-square values and the reference sound pressure is 20 micropascal for sound in air and 1 micropascal for sound in other media. |
