Radiated pressure
Acoustic pressure radiated by a speaker (supposed to be placed in infinite space and small comparing to the wavelength) is written:
.
Speaker response, defined as a ratio between radiated pressure and supply voltage, is given by
and depends on the volume velocity response
(ratio between volume velocity generated by the speaker and supply voltage).
This response therefore depends on the acceleration response of the membrane:
where
is an acceleration in center of a membrane.
