Abstract

The proposed design method starts with the identification of basic design concepts based on acoustical engineering judgement. Then, two complementary approaches are used to analyse the effectiveness of these basic design concepts as well as the effect of various manufacturing and assembly parameters on the noise level. The first approach is to conduct statistically designed experiments to identify key parameters, their effects and their interactions. The second approach is a finite element modelisation including a sensitivity analysis of the quadratic velocity as a function of key parameters
