Abstract:
1. A method for optimizing sound and vibration performance inside a mobile passenger compartment, comprising: establishing a list of comfort indices that are criteria defining quality of the sound and vibration performance and providing target values of the indices; establishing a list of requirements concerning some or all of the whole passenger compartment and relating to plural equipment suppliers, the requirements being information relating to exigencies other than those concerning sound or vibration comfort; defining input data influencing generation, propagation, and transmission of vibration and sound fields inside the passenger compartment, the input data being associated with plural equipment suppliers and certain input data being limited by requirements; estimating values of the passenger compartment comfort indices according to the input data; comparing the estimated values with the target values; when the estimated values do not match the target values, acting individually or in combination on some or all of the input data; and repeating in an iterative manner the estimating the vehicle comfort index values, comparing them with the target values, and acting on the input data, so as to ensure convergence of the values of the comfort indices with the target values.
