Universities

• Virginia Tech: fundamental and applied research in active noise control. Vibration and Acoustics Laboratory is directed by Prof. Chris Fuller, a pioneer in the field.
• University of South Hampton - ISVR: fundamental and applied research in all aspects of active noise control. One of the original institutions to perform research in the active noise control field.
• Southern Methodist University: Prof. Scott Douglas has developed a technique for fast multichannel Least Mean Squares (LMS) adaptive filtering that reduces computations in active control considerably.
• Oregon Graduate Institute: Prof Eric Wan's research has lead to the Adjoint LMS algorithm, a simple (not exact) fast LMS algorithm for multiple channel active noise control.
