Sound Quality Evaluation for Interior Noise of High-Speed Train

초록

This study presents interior noise characteristics of Korean high-speed train KTX-II comparing with European high-speed trains. The difference of spectra characteristics of trains with running speed increasing may have to make the Zwiker's loudness is higher even A-weighted sound pressure level is lower. When low frequency hands are dominant, Zwicker's loudness is more sensitive for high frequency band changed by aerodynamic noise than dB(A), and sharpness increases with increasing of high frequency bands.
