A BRIEF REVIEW OF ACTIVE CONTROL OF ENVIRONMENTAL NOISE AND ITS APPLICATIONS

摘要

Although active noise control has been intensively explored for several decades, its practical and successful applications are still limited to a few specific areas. Active control of environmental noise has also received extensive attention for many years. Examples include active noise control in open spaces, active noise control in enclosed environments, and active noise control barriers. However, the application of active control to real environmental noise problems has not yet enjoyed much significant progress, even though environmental noise, especially low-frequency environmental noise, is becoming an important issue that raises increasing concerns from communities. This paper reviews the progress made so far from studies of active control of environmental noise, and discusses issues affecting their practical application. Future directions of active environmental noise control research and its applications are also discussed.
