Abstract

The invention discloses a noise reduction method, which comprises the following steps of receiving a first sound signal; acquiring a frequency spectrum of the first sound signal, and determining a noise frequency spectrum in the first sound signal according to the frequency spectrum of the first sound signal; determining amplitude of the noise frequency spectrum in the first sound signal; determining a filtering parameter according to the amplitude of the noise frequency spectrum in the first sound signal; and filtering the first sound signal by using the filtering parameter in order to obtaina second sound signal. In addition, the invention further discloses an earphone and a computer readable storage medium. Therefore, according to the noise reduction method provided by the invention, different sound sources can be distinguished, the noise frequency spectrum can be separated from the frequency spectrum of the received sound signal, and the received sound signal is filtered accordingto the amplitude of the noise frequency spectrum, so that useless sound signals can be effectively reduced, and a noise reduction effect is improved.

Description

Technical field [0001] The present invention relates to the technical field of noise reduction processing, in particular to a noise reduction method, earphones and computer-readable storage media. Background technique [0002] With the continuous development of electronic technology, mobile terminals (such as smart phones, tablet computers, etc.) have brought great convenience to people's lives and work. In most cases, in order to avoid disturbing others or avoid interference from the surrounding environment, users will choose to use headphones. However, in the prior art, the mobile phone cannot distinguish different sound sources, and it is easy to attenuate useful sound signals or fail to reduce useless sound signals, resulting in poor noise reduction effects. Summary of the invention [0003] In view of this, the present invention proposes a noise reduction method, earphone and computer readable storage medium to solve the above technical problems. [0004] First of all, in ord...
