Abstract

In this study, sound source localization and identification of a refrigerator were accomplished by using the half-space boundary element method (BEM) based on surface velocity measurements. Surface velocities of the refrigerator were measured by a vibration test set-up; and two main dominant excitation frequencies were determined. The velocity data were fed to half-contact BE model of the refrigerator built in our “in-house” BEM computer code. The code calculated surface acoustic pressure distributions. The surface pressures exposed the location of sound sources of the refrigerator. Near-field sound radiation pattern of the localized sources were obtained by the surface pressure-input to the computer code.
