Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we performed nonlinear distortion reduction of earphones by equalizing input signal recursively. This distortion reduction method was invented by the authors. We did multiple experiments of non-linear distortion reduction for three types of earphones: canal type, intra concha type, overhead type. As the results, we confirmed the non-linear distortion reduction by canal type 7.4dB, intra concha type 8.6dB and overhead type 7.8dB for 1 kHz pure tone.
