In high-rise residential buildings, the elevator shaft and the partition wall of the resident are adjacent to each other with a common wall design, so when the elevator runs at high speed, there will be a large impact of rail vibration noise (such as an airplane or subway passing, and the noise can be as high as 50 dB). Shenri Rail Noise Reduction Technology installs elevator guide rail vibration reduction measures to block the transmission of vibration sources to the building wall, and solves the impact of elevator guide rail noise on nearby residents.
