Study of noise radiating from an internal combustion engine is of great interest and challenge to automobile engineers. Design of low-noise engines is becoming increasingly important because of progressively stringent regulatory requirements. Further, customers are demanding products that have pleasing sound quality. As any improvement in this area will have significant impact on image of the product, addressing these concerns will prove highly beneficial. Most of the critical engine performance parameters - power, fuel economy, and emissions - impact engine noise and sound quality. Therefore, to avoid intractable engine noise and sound quality problems later, it is very imperative to deal with them upfront in the development process.
