Abstract (en)
[origin: EP1138860A1] The device comprises a base plate (31) which is made from a sound-resistant centre part (3) connectable to the mechanical system and designed to connect two wing members (32a, 32b ) together. The wing members are each connected to a side part (22a, 22b) of a sound-resistant angular element (2a, 2b) through a sound-soft elastic layer (4a, 4b). The angular element has a base part (21a, 21b) connectable with the assembly body. The nature and dimensions of the two sound-soft layers is selected taking into consideration the incline of the wing members and side parts so that the assembled sound protection device expands the mechanism system into a vibration system whose resonance frequency is below the frequency range of disturbing sounds.
