Embodiment Construction

[0064] Further features and advantages will appear in the remaining description with respect to the schematic diagram of FIG. 1 .

[0065] According to the invention, a method for optimizing the sound and vibration performance of the interior of a motor vehicle cabin, such as a vehicle, in this case a motor vehicle, comprises the following steps in sequence:

[0066] - establishing a list of comfort indices as criteria for defining sound and vibration performance quality and providing target values ​​for these indices (box 1 of figure 1);

[0067] - establish a list of requirements (box 2) that correspond to information concerning all emergency situations, not just those related to sound or vibration comfort;

[0068] - definition of input data affecting the formation, propagation and emission of vibration and sound fields inside the passenger cabin (box 3), some of which can be associated with requirements (arrows from box 2 to box 3);

[0069] - Estimate the vehicle comfort...

Abstract

The invention concerns a method for optimizing acoustic comfort in a mobile vehicle passenger unit, the method being implemented by the designing team for providing the global design of the passenger compartment and/or at least one equipment manufacturer for providing the design of part of the passenger compartment, and consisting in establishing target values to be achieved for properly identified comfort indicators, in defining constraints and input data related to several equipment manufacturers to obtain overall data concerning the passenger compartment, in estimating the values of the comfort indicators and comparing them with the target values, and finally in modifying in isolation or in combination the input data to correlate them with the target values.

Description

technical field [0001] The invention relates to a method for attenuating sound and vibration disturbances in a passenger cabin, in particular in a motor vehicle, such as a vehicle, especially a motor vehicle. [0002] In addition to motor vehicles or other types of vehicles such as trucks, passenger cars, agricultural equipment, the invention applies to all kinds of moving equipment having an enclosed or substantially enclosed passenger compartment, such as airplanes, trains, ships, submarines, and the like. Background technique [0003] Among all the properties that contribute to comfort in modern vehicles such as trains and motor vehicles, sound and vibration comfort are becoming decisive factors. In particular, other sources of interference from mechanical, thermal, visual, etc. sources have been reasonably well controlled. However, new difficulties arise in improving sound and vibration comfort. [0004] Factors that can spoil the acoustic comfort in a vehicle include ...
