Abstract
The fast and accurate selection of soundproof pads of automobile dash panels and the promotion of car interior sound quality are studied. Based on the transfer function principle of the acoustic cavity, difference of the sound insulation performances of three soundproof pads of automobile dash panels, made of different materials, is analyzed. Through the comparative analysis, the PET + EVA + bicomponent cotton soundproof pad is selected. This article has offered real and effective test cases for the selection of soundproof pads of automobile dash panels and provided a reference for reducing the interior noise level of cars.关键词
