Abstract

The invention relates to a method for in-vehicle communication noise reduction, a vehicle-mounted terminal and a vehicle. The method comprises: receiving a rotating speed signal of an engine; determining an engine noise reduction signal corresponding to the rotating speed of the engine according to the rotating speed signal of the engine; when the vehicle-mounted terminal is in a call mode, performing noise reduction synthesis on a first voice signal received from call opposite-end equipment and the engine noise reduction signal to obtain a first target voice signal; and playing the first target voice signal. Through the technical scheme, the engine noise reduction signal can be quickly determined, so that the first voice signal can be accurately subjected to noise reduction in real time,the influence of noise generated by the engine on the communication quality is effectively reduced, the use requirement of a user is met, and the use experience of the user is improved.

Description

technical field

[0001] The present disclosure relates to the field of vehicles, and in particular, to a method for noise reduction in in-vehicle communication, a vehicle-mounted terminal, and a vehicle. Background technique

[0002] In the prior art, for communication noise reduction, an active noise reduction system is generally used to weaken the impact of environmental noise on call quality. However, the noise source targeted by the active noise reduction system is mainly the surrounding human voice, and its noise frequency is low, while the noise source in the car includes the high-frequency noise generated by the engine rotation. Noise reduction needs. Contents of the invention

[0003] The purpose of the present disclosure is to provide a method for noise reduction in in-vehicle communication, a vehicle-mounted terminal and a vehicle that can quickly and effectively reduce noise.

[0004] In order to achieve the above object, according to the first aspect of the pr...
