A sound absorption module can be laid on the track pavement in the platform area to absorb part of the direct sound of the wheel and rail and reduce the reflected sound of the wheel and rail on the bottom of the roadbed;
Decorative absorbing ceiling panels can be installed on the platform and station hall ceiling, and strong-absorption bodies can be installed on the platform floor side walls to reduce the impact of the direct sound and reflected sound of rail transit on the acoustic environment on the platform and station hall.
