Noise absorber solutionsGHH-BONATRANS pays close attention to the issue of noise. Our research and development department has developed a number of solutions reducing noise caused by railway wheel operation. GHH-BONATRANS achieves a reduction of the vibration (and thus also noise) of wheels in operation by application of specially developed noise absorbers mounted on the wheels. The noise absorbers made by GHH-BONATRANS are able to achieve absorption of the rolling noise by up to 5 dB(A), while the most unpleasant squealing noise of wheels equipped with GHH-BONATRANS noise absorbers is up to 30 dB(A) lower than that of wheels without absorbers, especially in the significant frequency bands. GHH-BONATRANS delivers complete systems specifically designed for different markets such as urban, suburban and passenger transportation as well as for high-speed and very high-speed trains.
