Potential NASA Commercial Applications: The proposed development will extend and enhance the computational modeling capabilities in many industries such as automotive, naval, heavy equipment and consumer products. Customers equate quality of a product with the sound the product makes. As a result of elevated demand for quieter products from customers together with the increased government regulations, manufactures of products with noise problem in all industries are searching for effective ways to make products with improved noise characteristics. For example, in automotive industry, the increased use of multi-media and telemetric devices demands quieter vehicle interiors and the manufactures and suppliers of interior products not only need to consider functionality, but also the noise control capability of the products. Consequently, there is increasing demand for tools based on computer simulation that can be used to guide design at the early design stage. In addition to interior noise prediction and optimization, the software can be adapted to evaluate and improve radiated noise from engines, exhaust, tires, etc. It can be used to evaluate and improve consumer products such as compressors, air conditioners, hairdryers, vacuum cleaners, and washing machines.
