Wilson Acoustics Limited


Founded in 2005, Wilson Acoustics Limited (WAL) is inventor of the Multi-Directional Tuned-Mass Damper (MDTMD) to mitigate railway noise. The damper is distinguished in reducing both vertical and lateral rail vibrations by oscillation masses, such characteristic enable the damper to provide exceptional high damping at rail vibration. It is able to suppress corrugation growth and noise radiation in long-term measurement. The remarkable performance parameters are listed as follows: Suppression in corrugation growth rate by 45% Rail noise reduction by ~4dB(A) Saloon noise reduction by ~3dB(A) Rail vibration reduction from 8 to 10dB(A)
