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 …

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. LAeq,T is the A-weighted Leq, measured over a specified period of time (T).

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.

2022年3月29日 · 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.

2012年6月30日 · Equivalent Continuous Sound Pressure Level, or Leq/LAeq, is the constant noise level that would result in the same total sound energy being produced over a given period. LAeq is a fundamental measurement parameter designed to represent a varying sound source over a given time as a single number.

When dealing with a new or proposed noise LAeq is often used [also written dBA Leq]; this term is the Equivalent Continuous Level. The formal definition is " when a noise varies over time, the Leq is the equivalent continuous sound which would contain the same sound energy as the time varying sound" .

Leq (Equivalent Continuous Sound Level) is a crucial metric in acoustics and noise studies, representing the average sound level over a designated period. It reflects sound energy and potential hearing damage due to cumulative exposure. What is the meaning of Leq in acoustics?

The Leq or Lavg is best described as the Average Sound Level over the period of the measurement. Usually measured with A-weighting, the Leq has no time constant applied, but the Lavg is usually Slow time weighted.

Leq (equivalent continuous sound level) is defined as the steady sound pressure level which, over a given period of time, has the same total energy as the actual fluctuating noise. Thus, the Leq is in fact the RMS sound level with the measurement duration used as the averaging time.

Leq = equivalent sound level. Noise fluctuates over a wide range of decibels, Leq meters store the fluctuating levels and calculate the 'average energy' or Leq value over the period of time of interest
