Abstract

Automotive cabin noise was experimentally evaluated with the operation of the vehicle, using psychoacoustic analysis techniques. Psychoacoustic, or quality of sound is considered to be a very important aspect in the development of a product with a sense of quality. Some of the common and uncommon psychoacoustic metrics include loudness, sharpness, roughness, fluctuation strength,brightness, pitch strength, impulsiveness, and speech interference level (SIL). Each matrics has a specific use and applicability that is dependant on the source of noise. In addition to the FFT analysis, the psychoacoustic metrics that were considered in this investigation include Zwicker loudness, fluctuation strength, and roughness. The purpose of using a binaural head was to acquire the acoustic data in a manner representative of what a human passenger would perceive. It is observed that predominated noise contribution within the vehicle cabin is the result of road and tire suspension interactions.
