When developing a noise control solution, it is beneficial to provide modeling of the system to optimize the resulting solution limiting testing to relevant solutions meeting the various constraint requirements of cost, performance, manufacturing, and shipping. A recent study on predicting sound transmission through vehicle panels to eliminate the multiplicity of testing needed to identify the best solution. This paper will present a study to identify a solution to improvement of the sound transmission of a vehicle panel leveraging modeling and comparing the model results to the actual test results. by comparing model predictions to test results from ASTM E90 - Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements1. Vehicle panels featuring distinct absorbing configurations identified through modeling were installed within a composite plug wall and subjected to standardized acoustic excitation. The agreement between model predictions and experimental data will demonstrate effectiveness of models in predicting panel performance.
