Problems solved by technology

[0003]However, the performance of the processor on the headset is limited, and it is impossible to use a highly complex algorithm, and the noise reduction effect in many complex situations is not ideal
The microphone on the headset has a large error in sound source localization, so the noise reduction effect on moving noise sources is not ideal
Moreover, noise-canceling headphones are relatively expensive, and the price is relatively high.

Abstract

The embodiment of the invention discloses a noise reduction method, terminal equipment and a computer readable storage medium, which are used for carrying out a noise reduction processing process on the terminal equipment, so that a user can experience a certain degree of noise reduction effect without extra cost. The method provided by the embodiment of the invention comprises the steps that the terminal equipment collects a sound signal; the terminal device obtains a first sound transfer function between the ear of a user and the terminal device; the terminal device processes the sound signal according to the first sound transfer function to obtain an ear noise signal; and the terminal equipment performs noise reduction processing on an output signal of the currently used earphone according to the ear noise signal.

Description

technical field [0001] The present invention relates to the audio field, in particular to a noise reduction method, terminal equipment and a computer-readable storage medium. Background technique [0002] When using earphones to enjoy music or movies, how to improve the listening experience in noisy environments has always been a concern of users. Currently, an active noise cancellation (Active Noise Cancellation, ANC) function has been widely used in earphones. To achieve active noise reduction, it is necessary to install a microphone and a processing circuit on the earphone. Usually, a microphone is installed on the earphone shell to collect ambient noise. Some active noise-cancelling earphones also install another microphone inside the earphone close to the speaker to collect the earphone and noise. The sound between the human ear. The signal collected by the microphone is processed by an algorithm to estimate the ambient noise reaching the ear, and then the anti-phase ...
