摘要

In this paper, we present the effectiveness of a software tool for eliminating nonlinear distortion through some experiments of eliminating the 2nd- and 3rd-order nonlinear distortions. We have presented some identification methods of loudspeaker systems and some elimination methods of nonlinear distortions. However, the software tool for eliminating the distortions has not been realized yet. We therefore develop the software tool. The realization of the software tool enables to identify loudspeaker systems and eliminate the nonlinear distortions. Experimental results show that the 2nd- and 3?d-brder nonlinear distortions of a loudspeaker system can be reduced in the range of 10dB to 20dB by the tool when noise level is below 70dBA.
