Problems solved by technology

However, the environment in which the user lives usually has noise. When the user listens to the other party's voice through the earpiece, the noise in the environment will also spread to the user's ears. In this way, the noise in the environment may interfere with the user's recognition of receiving the call from the earpiece. received voice, resulting in poor voice call quality of the terminal device

Abstract

The embodiment of the invention provides a telephone receiver noise reduction method and apparatus, applied to a terminal device. The terminal device comprises a first microphone MIC and a second MIC. The method comprises the following steps: obtaining an initial signal received by a telephone receiver; obtaining a noise signal collected by the first MIC, a playing dissipation coefficient of the telephone receiver and a noise dissipation coefficient between the first MIC and the second MIC, wherein the distance between the first MIC and the telephone receiver is greater than a first threshold, and the distance between the second MIC and the telephone receiver is smaller than a second threshold; determining a reverse noise signal according to the noise signal, the playing dissipation coefficient and the noise dissipation coefficient; and performing noise reduction processing on the initial signal according to the reverse noise signal. The voice call quality of the terminal device is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular, to a method and device for noise reduction of an earpiece. Background technique [0002] At present, many terminal devices (mobile phones, tablet computers, etc.) have a voice call function, and a handset is usually set in the terminal device, so that the user can listen to the other party's voice through the handset. [0003] When the user performs voice communication with other terminal devices through the terminal device, the user can listen to the voice of the other party through the earpiece of the terminal device. However, the environment in which the user lives usually has noise. When the user listens to the other party's voice through the earpiece, the noise in the environment will also spread to the user's ears. In this way, the noise in the environment may interfere with the user's recognition of receiving the call from the earpiece. received ...
