摘要
Abstract
The noises in the head vehicle, middle vehicles and vehicle’s connections of Shanghai Metro line 9 are measured respectively at different speeds. The objective evaluation of the measured interior noise is carried out according to the sound quality parameters of A-weighted sound pressure level, specific loudness, sharpness, roughness and fluctuation intensity based on the psycho-acoustical theory. The results show that most of the interior noises are low and middle frequency noises. The interior acoustic environments of the vehicles, especially of the vehicle’s connections need to be improved to satisfy the acoustic comfort requirement.关键词
