摘要：

This paper proposes a method of reducing nonlinear distortion in sound reproduction systems by recursively equalizing input signals. The proposed method has lower computational costs and modeling errors compared with conventional methods. A computer simulation was undertaken to confirm these advantages. An experiment for the proposed method was conducted using multi-loudspeakers as multi-sound sources. As a result, a reduction level of about 2 to 40 dB was achieved using the proposed method. In addition, it was found that the proposed method was particularly effective for frequency ranges lower than 8 kHz.
