PREDICTION OF NOISE EMISSIONS USING PANEL CONTRIBUTION ANALYSIS SUPPLEMENTED WITH SCALE MODELING

Gong Cheng
Panel contribution analysis (PCA) can be used to predict machinery noise emissions, component contributions, and to assess the impact of sound reduction treatments. PCA is a measurement approach that is advantageous for complex machinery that is not easily modeled using conventional numerical analysis approaches. In this research, PCA is combined with scale modeling in order to speed up the necessary measurement work. Moreover, the method can be applied to much larger machinery and noise emissions...
