Summary
Sound Pressure Level
(SPL) is a
Logarithmic measure
of the
Effective pressure of a sound
relative to a
Reference Value
, typically
20 micropascals in air
, which is the
Threshold Of Hearing
. SPL is expressed in decibels (dB) and helps quantify
Sound Intensity
, making it crucial in areas like acoustics,
Audio Engineering
, and
Environmental Noise Monitoring
.
