Aluminum sheet for sound barrier is a special aluminum sheet designed and used to solve the problem of train noise and vibration. It is mainly used in high-speed rail. It has excellent sound insulation performance and anti-vibration ability through special structure and materials. Acoustic aluminum sheets reduce noise levels inside and outside the vehicle by absorbing, reflecting and isolating noise. It can reduce the impact of train vibration on carriages and passengers. It has good shock absorption and anti-vibration properties, which can effectively reduce the vibration and vibration generated during train driving, and improve the stability and riding comfort of the train.
