Synthesis of car noise based on a composition of engine noise and friction noise

This paper describes a method for generation of car noise based on the engine noise and the “friction noise.” The engine noise is modeled by composition of a stationary background noise that depends on the size of the engine and nonstationary noise that depends rotational speed of the engine. The friction noise is modeled as a white noise with ranging power. Based on these models, methods for synthesis of these components are developed. Subjective assessment of the car noise synthesis method shows that it is fairly similar to the actual noise.
