Contribution of sound package components to airborne attenuation 2010-36-0328
In South America and other emerging markets sound package
development is limited by the cost and weight of its components.
Reaching the right balance between cost and a good NVH performance
provides an important competitive advantage, therefore any achieved
design opportunities can be replicated to other vehicle lines and
markets.
In this work the main noise transmission paths are verified by
evaluating the contribution of sound package components to noise
attenuation in two cases, initially from the tire contact patch
through vehicle body to a number of positions within the vehicle
interior and, next, from the engine compartment, by placing a High
Frequency Sound Source (HFSS) at engine faces to the same vehicle
interior positions.
The main objective is to optimize sound package distribution and
to prioritize which areas should have the sound package reinforced
in order to improve Tire and Engine noise reduction. On the other
hand, sound package parts placed in areas that are less demanded
can have its weight reduced.
