2.2. Is active control new?
The idea of active noise control was actually conceived in the 1930\u2019s
(see the Lueg patent mentioned below), and more development was done
in the 1950\u2019s. However, it was not until the advent of modern
digital computers that active control became truly practical. Active
control became a "mainstream" research topic in the 1970\u2019s and
1980\u2019s, and in recent years research papers have been published at
the rate of several hundred per year. There are now several rather
large companies that specialize in active control products, and the
topic is widely studied in universities and government research
laboratories.
