Study on Wind Noise Reduction using Neural Network for Hearing Aids
Katsuya Arimoto, Yoshihisa Nakatoh · 2018
Currently, there are 3.4 million hearing aid wearers in Japan, and it is said that one-ear wearers are about 60% of them. In addition, wind noise is one of the reasons for interfering with listening when a hearing aid is used outdoors. In this study, in order to eliminate wind noise in a one-ear hearing aid, we proposed a method to estimate wind noise using GAN, and to eliminate wind noise every moment based on the spectral subtraction method. As a result of evaluating the effectiveness, we showed that by removing wind noise in In-the-Ear hearing aid and Behind-the-Ear hearing aid, speech with 70% or more correlation with ideal sound can be generated.
