Overview of the application of active noise control technology in the indoor acoustic environment

Abstract

Passive noise reduction technology is not enough to improve the acoustic comfort of the indoor acoustic environment. This paper discusses the application prospects of active noise control technology in the indoor acoustic environment, studies the principle and development status of active noise control technology, describes the determinants of the effect about the active noise control and the application prospects in the indoor acoustic environment, and points out the current problems to be solved in the research and future research directions.
