Noise Unit has been played on NTS shows including Night Shift w/ Diamondstein, with Dry Lungs first played on 17 October 2017.

One of the many sideprojects of Bill Leeb, Noise Unit has a steady electronic danceable beat, comparable with the more ebm-styled releases of the mother band Front Line Assembly. The first N.U. releases, 1989's Grinding Into Emptiness and 1990's Response Frequency, were a collaboration between Leeb and Marc Verhaeghen of (The Klinik).

Verhaeghen left after second album, and Noise Unit became simply another FLA pseudonym. 1994's Strategy of Violence is probably the most notable release from the project. With the release of their fourth album, Decoder, in 1995, N.U.'s style had begun to embrace some influences from trance, while maintaining the aggressive quality of their earlier, more industrial sound. This is a direction Noise Unit has developed further with later releases.

With many varying members over the years, they have included: Bill Leeb (Front Line Assembly, Delerium, early Skinny Puppy), Marc Verhaeghen (Klinik), Daniel Myer Haujobb), Rhys Fulber (Front Line Assembly, Delerium) and Chris Peterson (Front Line Assembly, Will, Decree).
