| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we demonstrate the compensation effect of nonlinear distortion of loudspeaker systems by using dynamic distortion method. The swept sine wave is usually used for the verification of the compensation effect of nonlinear distortion. However, the evaluation result is not always corresponding to hearing sense because the signals input to loudspeaker systems are a wideband like music and voice. We therefore use dynamic distortion method by white noise which is a wideband signal. We design two linearization systems which using Volterra filter and Mirror filter which using the linear and the nonlinear parameters of a loudspeaker system estimated by Simulated Annealing(SA), and examine the effectiveness on compensating nonlinear distortions of the loudspeaker system. Experimental results show that the dynamic distortion method has effectivity. |
