Through the last cooperation, NCC Bo Heng once again cooperated with Hefei Metro and quickly completed the construction of the soundtrack room.

Hefei Metro Line 2 wheel pairing test table-sound insulation room is designed to reduce the noise generated during the running test process. 

This sound insulation room is usually located near the running test table. By using special sound insulation materials and structures, 

it effectively blocks the spread of noise, thereby reducing interference in the surrounding environment.
