Dynamic Noise Reduction

Because DNR is non-complementary, meaning it does not require encoded source material, it can be used to remove background noise from any audio signal, including Magnetic Tape recordings and FM Radio broadcasts, reducing noise by as much as 10 dB. {Link without Title} It can be used in conjunction with other noise reduction systems, provided that they are used prior to applying DNR, to prevent the other noise reduction system from mistracking.

One of DNR's first widespread applications was in the high-end GM Delco Bose Car Stereo systems in U.S. GM cars, introduced in 1984. Today, DNR is most commonly encountered as a noise reduction system in microphone systems.[http://www.hellodirect.com/catalog/Product.jhtml?PRODID=11127&CATID=15295
