Abstract :
The Doppler effect in loudspeaker, in which high- and low-frequency signals exhibit a weak frequency intermodulation, is considered. A more general time-dependent formulation of this effect is derived in which the nonlinearity is interpreted as a signal-dependent delay operator. It is shown that for high acoustic power densities the associated distortion phenomena have to be taken into account
