Sterilisation der Verbandstoffeion for active noise control that is limited to electro-dynamical actuation by loudspeakers and electro-dynamical exciters. The first actuator type is widely used as secondary sound source. The second one is of special interest, if an elastic structure is to be used as an acoustical source. The equa

To show the practical use of the proposed (matrix) design approach, considering the mechatronic background of feed-forward ANC presented in part I as well as the ANC-system design tools discussed in Chap. ., this chapter reports on five successive design steps

This makes the adaptation and implementation of such systems plausible in vehicles such as automobiles and aircraft where passive reduction methods are restricted. Taking into account that both automobiles and aircraft are

For this purpose it is essential to determine both positions and source strengths of the primary noise sources. These information are required
