# What is dB a leq?

**dB(A) Leq**denotes the time weighted average of the level of sound in decibels on scale A which is relatable to human hearing. "A", in

**dB(A) Leq**, denotes the frequency weighting in the measurement of noise and corresponds to frequency response characteristics of the human ear.

Hereof, what is Leq in noise measurement?

**Leq** (or LAeq) is the Equivalent Continuous **Sound** Pressure Level. 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.

Beside above, how is Leq calculated? The equation to **calculate** Leq divides the integrated, normalized sound pressure by the duration of interest of the signal. The result is expressed in units of decibels: p0 = reference pressure level (typically 20 µPa) pA = acquired sound pressure.

People also ask, what is LAeq dB?

**LAeq** is the A-weighted equivalent continuous sound level in decibels measured over a stated period of time **LAeq**,T. Most community and industrial noise measurements are A-weighted so the **LAeq** descriptor is widely used.

What is LMAX in noise?

Understanding **Noise** Measurements – **Lmax**, Lmin and Peak **Lmax** is the RMS (root mean squared) maximum level of a **noise** source or environment where peak is the maximum level of the raw **noise** source. **Lmax** is the highest RMS **sound** pressure level within the measuring period.
