Sound Energy Density Level




It is the ratio of two sound energy densities ''E'' or ''w'', and ''w''0.


DEFINITION


The sound energy density level ''L''E is:
:
L(E)=10\, \log_{10}\left( rac{E_1}{E_0} ight){ m dB}


where ''E''1 and ''E''0 are the energy densities. The unit of the sound energy density level is "dB-E".

If ''E''0 is the standard reference Sound Energy Density of
:
E_0 = 3 \cdot 10^{-15} \mathrm{ rac{W \cdot m}{s^3}}


we chose instead of "dB" the unit "dB SE" (SE = sound energy density level).
