Sound - L_s - Exposure Level

The EPA Sound Exposure Level - L_s - describes the noise from a variable source.

Sound Exposure Level - L_s

The Sound Exposure Level - L_s - measures the sound change from moment to moment with variable sound. The maximum sound level and the length of time with the sound level greater than certain sound pressure levels are measured.

By accumulating intensity and exposure duration the total sound energy can be measured.

Sound Exposure Level - L_s - can be used to describe noise from moving sources such as airplanes, trains, trucks, etc.
