Summary:

In South America and other emerging markets sound packagedevelopment is limited by the cost and weight of its components.Reaching the right balance between cost and a good NVH performanceprovides an important competitive advantage, therefore any achieveddesign opportunities can be replicated to other vehicle lines andmarkets.In this work the main noise transmission paths are verified byevaluating the contribution of sound package components to noiseattenuation in two cases, initially from the tire contact patchthrough vehicle body to a number of positions within the vehicleinterior and, next, from the engine compartment, by placing a HighFrequency Sound Source (HFSS) at engine faces to the same vehicleinterior positions.The main objective is to optimize sound package distribution andto prioritize which areas should have the sound package reinforcedin order to improve Tire and Engine noise reduction. On the otherhand, sound package parts placed in areas that are less demandedcan have its weight reduced
