Compensation of Nonlinearities of Horn Loudspeakers
This paper presents an compensation method of nonlinearities of horn loudspeakers. It is possible to compensate the nonlinearities effects of electroacoustic devices by applying the inverse nonlinearity upstream. The method is based on the measurements of the nonlinearity by Volterra series using multitone excitations. Once the Volterra kernels has been determined, we proceed by computing the inverse Volterra kernels, both in magnitude and phase. The method was implemented and validated in non-real time and real time (DSP implementation). To validate the nonlinearities compensation a comparison between total harmonic distortion measurements with and without compensation has been done.
