Abstract
Active Control of Sound (ACS) is a promising method for
noise control. However, only a few applications are
commercially attractive. One of the main problems has
been the non-availability of good actuators for
anti-sound production. Flat EMFi sensors and actuators
can be easitly implemented in ACS applicaitons, where
large surfaces are to be covered with sensors and/or
anti-sound producing elements. Some promising results of
the use of EMFi-technology in ACS are presented.
Application areas include the reduction of noise entering
the cabins of cars and trains and the increase of sound
transmission loss in building elements.
