Active Noise Control and Acoustic Modification
Traditionally, the acoustical engineering community has taken the point of view that it is better to avoid noise problems at the design stage than eliminate them later. When problems do occur, the traditional and probably the most straightforward way of solving them is through the application of passive methods, such as acoustical absorption, isolation mounts, and the like. These methods are probably the most effective way of combating broadband noise in large public assembly spaces.
