Experimental verification of sound power determination methods based on radiation matrix.
Original language description
The theoretical foundation of sound power determination from a sound radiating surface using volume velocity and acoustic radiation matrix (ARM) is well established in the literature. However, a detailed experimental investigation of the accuracy of this method over a wide frequency band has not been presented. In this study, the ARM method is analyzed thoroughly to identify factors that can affect the accuracy of the calculated sound power. To do so the acoustic radiation matrix is observed closely as this is the main parameter responsible for determining the sound power. Further experiments were performed to calculate the sound power using the ARM method and results were compared to those obtained using the ISO 9614–2 and Rayleigh’s Integral Method (RIM). Comparison of these results in wide frequency bands provides insight into the acoustic radiation matrix based on the assumptions made during the modeling of the ARM method. These insights are then used to improve the model’s accuracy with the motivation to apply this method to the in-situ measurement of the large building facades.
