Normal incidence transmission loss of sandwich structures in a plane wave tube
2006 (English)In: International Congress on Sound and Vibration 2006, 2006, 317-324 p.Conference paper (Refereed)
The Transmission Loss of different kind of layered structures is investigated by means of a four microphone technique in a plane wave tube. By using the decomposition technique, incident, reflected and transmitted contributions are separated and transmission coefficient is easily calculated. In this paper a single measurement approach based on transfer matrix, taking into account reflection contribution from the end termination, is presented. Results are discussed and compared with similar techniques and with the two-load method.
