NOISE REMOVING EARSET USING SOUND RECEIVING CHARACTERISTICS OF IN-EAR MICROPHONE AND OVER-THE-EAR MICROPHONE, AND NOISE REMOVING METHOD

WIPO Patent Application WO/2018/147573

A1

A noise removing earset using sound receiving characteristics of an in-ear microphone and an over-the-ear microphone, and a noise removing method are disclosed. According to the present invention, the noise removing earset using sound receiving characteristics of an in-ear microphone and an over-the-ear microphone, and the noise removing method: remove a user voice from an in-ear microphone signal and an over-the-ear microphone signal so as to extract noise; calculate a noise correction value to be mutually applied to each of the in-ear microphone and the over-the-ear microphone so as to correct the noise; and respectively remove corrected real noise from the in-ear microphone signal and the over-the-ear microphone signal so as to restore the user voice. According to the present invention, internal noise and external noise respectively inputted to microphones provided inside and outside are corrected into real noise in consideration of hardware characteristics, environmental characteristics, and the like, and then removed, thereby enabling the user voice to be more clearly outputted. Therefore, the user voice can be clearly transmitted to a counterpart regardless of the shape of an earset, an earset worn state, a very noisy place such as a performance stage, and the like.
