Analysis of Interior Noise Quality in a Special Vehicle
摘要
Abstract
Aiming at the interior sound quality problem of a special vehicle,the sound quality analysis was carried out.With sound signals of key parts in the operator cabin being acquired under various vehicles driving condition,the psychoacoustics objective evaluation parameters were analyzed in detail such as loudness,sharpness,fluctuation and roughness.Based on the comprehensive evaluation of interior noise of the special vehicle,it was concluded that the loudness level is over high under various conditions.Lastly,by means of filtering analysis method,the main frequency band of interior noise was found.关键词
