MIMOS-利用客觀量測及模式計算噪動及噪音的主觀影響
MIMOS-A New Method for Determining the Subjective Effects of Sound and Vibration Using Objective Procedure and Calculation Models
並列摘要
Noise and Vibration inside cars often presents a difficult task for the acoustic engineer. Because this events in cars arise in a complex way, direct conclusions about sound components subjectively judged to be annoying with regard to their causes and transmission paths, can be drawn in a limited way only. A new procedure, complementing binaural measurement technology and tested by including multi-channel measurements of acceleration sensor signals, sound radiation, transmission and calculation, has been developed. This involves correlating signals influencing sound quality, analyzed by means of human hearing, with signals from different acceleration sensors fixed in front of and behind engine mounts. An exact relationship between physical causes and subjectively perceived sound quality can be established.
