Noise treatment method, device and system

Abstract

The present invention provides a method, device and system for noise processing. The method includes: acquiring the sound in the car interior space and the reference sound of the car sound effect system; The sound of the car sound system is processed; the sound quality parameters (gain information, sound quality parameter Q value, center frequency) are determined according to the spectrum information of the processed sound; the spectrum information of the sound to be played by the car machine in the car is adjusted according to the sound quality parameters, and the obtained The polished car machine plays the sound and outputs it through the car machine sound system. By polishing the sound to be played by the in-vehicle machine and finally outputting the polished sound of the in-vehicle machine, it reduces the annoyance of the noise in the car to the occupants in the car, provides a comfortable acoustic environment for the users in the car, and improves the user's ride experience.

Description

Technical field [0001] The present invention relates to the noise processing technology, and particularly relates to a method of processing the noise, device and system. Background technique [0002] Sound acoustic vibration generated by an object, can be transmitted through the medium (air or a solid, liquid) and can be perceived by the auditory organs of fluctuation, which further comprises a noise. [0003] People often carried out in a relatively closed space everyday activities, especially when multiple memory devices and machine systems, and more prone to noise in an enclosed space, causing people irritability, serious harm to human health. [0004] With the improvement of people's living standards, the requirements for life comfort are increasing. The rapid development of the automotive industry has made people 's continuous pursuit of comfort quality, and weaken even eliminate noise inside the vehicle. The prior art mainly performs noise reduction processing inside the ve...

AI Technical Summary

Problems solved by technology

The existing technology mainly uses passive noise reduction or active noise reduction to reduce the noise inside the vehicle. The passive noise reduction method mainly uses sound insulation, sound absorption, and sound-absorbing materials to reduce noise; However, the existing technology still cannot meet the requirements of vehicle interior noise comfort, and cannot provide a comfortable and adaptive acoustic environment for the vehicle interior space.
