Active noise control

As mentioned in the first part of this paper, developments in microelectronics and digital signal processing in the 1980s led to the creation of adaptive active control systems capable of providing optimal control of secondary sources at any time and without external action. This progress was decisive, and led to the first industrial applications of active control in the 1990s.

After describing the architecture of a modern active control system, this article provides an overview of current active control applications and current studies.
