When applying the direct transmissibility approach to TPA (Transmission Path Analysis) in large closed domains, one is often faced with the practical difficulty that has not enough measuring channels to monitor the whole boundary surface (e.g., all panels in a train’s coach). One way to circumvent this difficulty consists in using the so-called control microphones. These microphones are used to account for the boundary pressure in a virtual surface. Unfortunately, the use of control microphones seems to be rather problematic in practice. In this project, errors arising from the limited amount of control microphones used in measurements have been analyzed and minimized to some extent through data processing techniques.
