Abstract

The invention discloses a method and a device for adjusting the volume of a car stereo. The method for adjusting the volume of a car stereo comprises: collecting sound signals inside a car, analyzing and processing the sound signals, and filtering playing sound signals of the car stereo to obtain noise signals; analyzing the noise signals and determining the specific content of the noise signals; and adjusting the volume of the car stereo according to the specific content of the noise signals and a preset volume adjusting scheme. By the technical scheme of the invention, the volume of the car stereo is adaptively adjusted according to the specific content of the noise signals, thereby optimizing the way of adjusting the volume of the car stereo.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a method and device for adjusting the volume of an automotive audio system. Background technique [0002] With the continuous development of people's living standards, cars have become a common means of transportation for people, and many people like to listen to music or the radio while driving to eliminate fatigue and obtain entertainment. However, when the car is running, the intensity of the noise signal in the car will also change with the change of the speed, road conditions and the use of the windows. Therefore, in order to obtain a better listening effect, the driver often needs to manually adjust the car audio. volume, and this will distract the driver's attention to a certain extent, increasing traffic safety hazards. In addition, when people in the car are talking or answering calls, in order to avoid the interference of the conversation or telephone co...
