Sound energy density level
- Sound energy density level
The sound energy density level gives the ratio of a sound incidence as a sound energy value in comparison to a reference level of 0 dB (DIN 45630). It is a logarithmic measure of the ratio of two sound energy densities.
Definition
The sound energy density level "L"E is::
where "E"1 and "E"0 are the energy densities. The unit of the sound energy density level is the decibel (dB).
If "E"0 is the standard reference sound energy density of[DIN 1320: Acoustics, Version 1997-06, Beuth publishing] ]:
