EXPERIMENTAL VALIDATION OF SEMIEMPIRICAL MODEL BASED ON ACOUSTIC RADIATION MATRIX METHOD
Original language description
Sound power determination using the surface velocity of the source has been a research interest for a long. While the theoretical foundation of this method is well-established in the literature the experimental validation of this method has still not yet been explored satisfactorily. To provide experimental support for this method and to discuss its limitations this work emphasizes on the experimental approach. In this work, a flat plate, vibrating in the air medium is studied for the determination of radiated sound power from a vibrating structure. To do so a semi-empirical model based on a radiation resistance matrix and source surface velocity is exploited. The radiation resistance matrix was calculated theoretically using two attributes of the source and medium say the geometry of the radiating source in this case a flat square plate and the density of the radiating medium respectively. On the other hand, another quantity required for the sound power determination namely the surface velocity was measured experimentally using laser scanning. Using this radiation matrix and surface velocity the radiated sound power was calculated and the obtained results were compared with the standard methods. Unlike the archived studies on this method, this work aims to implement this method for designing the appropriate measurement techniques for the acoustic performance of the large building envelopes having flexible façade.
