Test and loudness analysis of interior noise for the alu minu m alloy metro vehicle
摘要
Abstract
Metro vehicle interior noise affects the comfort of passengers directly.Mastering the interior noise characteristics can give theoretical reference to car body structure acoustic design and interior acoustic environ-ment optimization for metro vehicles.In reference of the national standards,the interior noise of the aluminum al-loy metro vehicle were tested at different speed to gain the interior noise spectrum characteristics.According to psychoacoustical theories which can reflect the subjective audition and loudness characteristics of interior noise of the tested metro vehicle.And the difference of assessing the interior noise between the sound level and the loud-ness level were compared.The suitable frequency range of noise reduction was suggested.关键词
