Modeling and Compensation of Nonlinear Distortion in Horn Loudspeakers
The horn loudspeaker suffers from producing high distortion. Based on a physical model, an equivalent lumped-parameter circuit is determined for a horn-loaded compression driver. From the nonlinear differential equation of this circuit, a compensation algorithm is implemented on a digital signal processor for reducing nonlinear-distortion caused by the behavior of air. Test results are presented.
