Active Noise Control: From Analog to Digital – Last 80 Years

Beginnings in the field of active noise control date from 1930s. From these pioneer attempts great deal of progress has been achieved. In this brief review paper advances from simple fixed analog systems, manually adaptive analog systems, acoustic feedback neutralization, fully adaptive digital systems with secondary path modeling and multichannel systems are briefly presented. Applications of active noise control in closed and open space, industrial and automotive applications, as well as active noise canceling headphones and new solutions with smart materials are also briefly mentioned.
