Abstract [en]

This article focuses on computer noise analysis and noise reduction processing.

With the popularity of computers, people are increasingly demanding the comfort of using computers.

Solving the noise problem of the computer case can make the working environment more comfortable.

People working in a noisy environment for a long time can cause anxiety and the quality of work is not high.

The main purpose of this paper is to analyse the characteristics of computer noise and to reduce the noise of the chassis through the secondary sound source.

Through the comparison of the experimental and simulation results, the noise reduction effect of the secondary sound source on the computer case is obtained.

This paper can provide a scientific reference for the manufacture of computer chassis and improvement of noise.
