摘要
有源降噪是利用声波的干涉,使得在噪声控制区域内的噪声与次级声波发生干涉根消,来达到控制或消除噪声的目的,因此,其基本原理是声波干涉理论.本文对有源降噪的基本原理。
The method of active noise absorption is based on interference of sound waves to control orabsorb the sound, hence its fundamental principle is sound wave interference theory- This paperpresents the fundamentals, physical realizations, applied directions and present problems.
