Soundproofing and sound-proof characteristics of locomotive cabs
The results of experimental researches of soundproof and sound absorbing characteristics of locomotive cabins are presented. Sound insulation, both single-layered and multilayered protections of cabins with the application of vibration absorption, sound-proof and sound absorbing materials is investigated. Researche to carried out allow to make a selection of materials and their combination for maintenance of the required sizes of a sound absorption and sound insulation.
