Researches on Sound Environment in Futian Underground Railway Station

Futian Railway Station, an underground station located in the downtown of Futian District, Shenzhen, went into operation in November 2015. It was the first underground station being in the center of downtown in China, the biggest underground station in Asia and had the fastest train passing through in the world. The passenger transformation hall in Basement one, the waiting hall in Basement two, and the railway platform in Basement three all got into trouble of acoustics. The highlight issues were the Reverberation Time (RT) and the Speech Transmission Index (STI) in such a huge narrow space. The acoustic lab of school of architecture, Tsinghua University, by studying the acoustic environment in similar narrow spaces in China and doing some computer simulation analysis, solved this acoustic problem successfully.
