Abstract Share this page

A study is described in engineering for customer preference focusing on solidness of closing sound for the automobile door. Customer preference is quantified and correlated with several characteristics of the measured sound pressure signal. The most significant characteristic is the high frequency content. A system model predicting this quantity is created. First, a series of experiments identified the important closing sound paths. Further experiments identified the impact of elements within the door latch to be the vibration source. An analytical model is developed which predicts closing sound spectral content based on latch mechanism and panel properties. Panel behavior is described using Statistical Energy Analysis principles. An improved design is proposed and the model used to show its superiority.
