Leq (said “L E Q”) stands for Equivalent Continuous Sound Pressure Level, and is one of the most important sound level metrics. It’s nice because it boils a sound level measurement down to one decibel level number. The Leq represents the total sound energy logged over the course of a …

Mar 29, 2022 · The equivalent sound level (LEQ) measures the average acoustic energy over a period of time to take account of the cumulative effect of multiple noise events. This could, for example, provide a measure of the aggregate sound at a location that has airplane flyovers throughout the day.

Equivalent Sound Level - Leq - quantifies the noise environment to a single value of sound level for any desired duration. It is designed to represent a varying sound source over a given time as a single number. Leq is also sometimes known as Average Sound Level - LAT even if this is not.

Leq : equivalent continuous sound level is the sound level in decibels, having the same total sound energy as the fluctuating level measured. Leq is also known as the time-average sound level (LAT). LAeq is the A-weighted, equivalent continuous sound level, in decibels having the same total sound energy as the fluctuating level measured.

For example, if a worker’s exposure consists of two distinct exposure periods, 3 hours at an Leq of 84 dBA and 5 hours at an Leq of 88 dBA, then: For a shift length greater or less than 8 hours, the Lex,8 may be calculated using the equation: Lex,8 = Leq, T +10 Log (T/8), where T is the shift duration in hours.

The EPA Equivalent Sound Level - Leq - quantifies the noise environment to a single value of sound level for any desired duration.

The EPA Equivalent Sound Level - Leq - quantifies the noise environment to a single value of sound level for any desired duration.

Jan 8, 2024 · Enter the sound levels in decibels (dB) and corresponding time intervals in seconds into the calculator to determine the equivalent continuous sound level, known as Leq. The Leq represents the steady sound level that, over the same period of time, conveys the same sound energy as the varying levels.

Leq stands for “Equivalent Continuous Sound Level,” a fundamental metric in acoustics and noise studies. Leq represents the average sound level over a designated period, treating fluctuating sound levels as equivalent energy to a constant sound level.

Leq sound levels are logarithmic (dB) values and cannot be added directly. A doubling of sound level results in a measured increase of 3 dB, four identical sources in a room would increase the noise level by 6 dB and so on.
