本文根据消声的基本原理,提出了若干消噪声的措施。在取得实验数据的基础上,设计制作了气垫导轨气源(吹尘器)的消声箱,经鉴定消声效果良好,已用于我系实验室气垫导轨气源的消声。
Based on the basic principles of noise cancellation, this paper proposes several measures to eliminate noise. On the basis of obtaining the experimental data, the anechoic chamber of air cushion air guide (blower) was designed and manufactured. The anechoic chamber has been identified to have good anechoic effect and has been used for the anechoic of air source of laboratory airway guide.
