,Die Wirkungsgröße im Hemmungsversuch,e for ANC-system design. It is based on five overlapping design steps. Every design step requires the handling of specific design tasks. Successful processing of these design tasks enables successful completion of design steps. This is expressed by an increase of system maturity. The latter is asses

Sterilisation der Verbandstoffeoth the idea and the limits of active control. Furthermore, it will be necessary to describe the interior noise problem and to distinguish between different concepts that can be used to reduce interior noise by means of active control. The upcoming chapter is therefore subdivided into four sections.

Sterilisation der Verbandstoffer filled interior. To establish a control concept, it is important to know what field variables can be used to describe the transfer behavior of this basic system or to receive information about the systems state. For this reason, basic acoustic field variables such as the acoustic pressure, the aco

Wesen und Bedeutung der Sterilisationthe state of interior noise fields is based on the observation of the acoustic pressure. This field variable is detected by microphones. Vectorial field variables such as the sound intensity can be approximated by sound pressure measurements, using two (or more) microphones. However, in some applica
