Résumé

The automotive intake noise was analyzed using a psychoacoustic metrics. The psychoacoustics involves the quantitative evaluation of acoustic sound pressure level using a sound quality metrics. The metrics includes loudness, sharpness, roughness, fluctuation strength and articulation index. Loudness a standard metric describes the human preception of loud source perceived as opposed to a simply reported sound pressure level. Roughness and fluctuation strength describes the annoyance of modulating sound and sharpness describes the high frequency annoyance of noise by applying a weighting factor on sounds above 2kHz.
