Statistical Energy Analysis Model for Sound Pressure Level Prediction on Refrigerators

Statistical Energy Analysis Model for Sound Pressure Level Prediction on Refrigerators A statistical energy analysis (SEA) model of a 510 l capacity refrigerator is used to calculate the sound pressure level generated in a reverberation room. This is a reliable indicator of the vibroacoustic performance of the refrigerator, and it is in some countries as a pre-commercialization test. The main contributions of the SEA model are the characterization of the refrigerator structure (three-layer: HIPS, polyurethane foam and steel) and the modelling of important components such as internal chambers or ventilation gratings. The simulation results are successfully compared with laboratory measurements. The SEA model is then used to understand the vibroacoustic behaviour of the refrigerator and to establish the most critical transmission paths and radiation mechanisms. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acoustics Australia Springer Journals

Abstract

A statistical energy analysis (SEA) model of a 510 l capacity refrigerator is used to calculate the sound pressure level generated in a reverberation room. This is a reliable indicator of the vibroacoustic performance of the refrigerator, and it is in some countries as a pre-commercialization test. The main contributions of the SEA model are the characterization of the refrigerator structure (three-layer: HIPS, polyurethane foam and steel) and the modelling of important components such as internal chambers or ventilation gratings. The simulation results are successfully compared with laboratory measurements. The SEA model is then used to understand the vibroacoustic behaviour of the refrigerator and to establish the most critical transmission paths and radiation mechanisms.
