Strategies for active and passive noise control

Robert J. Bernhard

Abstract


Noise control is a very crucial issue to be handled since the environmental concerns have become quite important. It involves careful diagnosis of the noise problem, prediction and design of various elements of the problem and application of best technology to solve the problem. Proper tools should be designed by the practicing engineers to curb the problem. Researchers should work to develop new technology. Noise will be effectively controlled once everyone contributes in this direction.
