Embodiment Construction

[0041] In order to solve the problem of environmental noise affecting call quality in the prior art, the present invention provides a method and device for suppressing environmental noise. The following further describes the present invention in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but do not limit the present invention.

[0042] Such as figure 1 As shown, the embodiment of the present invention relates to a method for suppressing environmental noise, including the following steps:

[0043] Step S101, obtaining the lowest environmental noise intensity threshold value and the highest environmental noise intensity threshold value;

[0044] In this step, the lowest environmental noise intensity threshold refers to the lowest intensity at which environmental noise affects the quality of the call during the call between the calling party and the called par...

Abstract

Disclosed are a method and a device for suppressing ambient noise. The method comprises the following steps: acquiring a lowest ambient noise intensity threshold and a highest ambient noise intensity threshold; and during a call, filtering out a voice signal whose intensity is greater than the lowest ambient noise intensity threshold and smaller than the highest ambient noise intensity threshold in an original voice signal, so as to obtain a first processed voice signal. By acquiring the lowest ambient noise intensity threshold and the highest ambient noise intensity threshold, and filtering out noise between the two thresholds during a call, the present invention can greatly reduce background noise in a noisy environment and improve the quality of a voice signal of the call, and has advantages of low cost and high flexibility.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method and device for suppressing environmental noise. Background technique [0002] With the continuous development and popularization of mobile communications, mobile communications occupy an increasingly important position in people's daily lives. At the same time, users of mobile terminals have increasingly pursued the functions and various aspects of mobile terminals. With the development of mobile terminals today, there are some unavoidable problems, including call quality. There are many factors that affect the quality of calls. In addition to the quality of the network, signal, and terminal itself, the most critical factor is environmental noise, especially in large cities, industrial factories and other places. The presence of these noises greatly affects the quality of normal calls, and even makes normal calls impossible to proceed, seriously affect...
