Statistical Energy Analysis And Optimization of Dash Sound Package
Dash sound package is the most important means to block the noise in cabin from transmitting to vehicle.This paper builds the SEA model,analyzes the sound insulation performance of the inner enclosure from the aspects of material parameters,thickness and coverage,analyzes the sound insulation performance of the perforated parts in terms of leakage,and optimizes the dash sound package of the front enclosure,so as to improve its sound insulation performance and reduce the noise in vehicle.
