Equivalent Sound Level definition

Equivalent Sound Level. , sometimes denoted as Leq, means the value of the constant Sound level which would result in exposure to the same total A-weighted energy as would the specified time-varying Sound, if the constant Sound level persisted over an equal time interval and is measured in dB(A);
Equivalent Sound Level. (also "average sound level") means the level of a constant sound which, in a given situation and time period, would convey the same sound energy as does the actual time-varying sound during the same period. Equivalent sound level is the level of the time weighted, mean-square, A-weighted sound pressure. A numerical subscript may be used to indicate the time period under consideration; i.e., Lea(24) or Lm(8) for 24-hour and 8-hour periods, respectively. No subscript indicates a 24-hour period. The mathematical expression for the Leq is as follows:
