Viscoelastic Materials for the Attenuation of the Vibrations Produced by Fitness Vibration Machines

New laws in the scope of acoustics are searching a major index of noise reduction and vibrations through the constructive elements. There is a great interest to work in the research of new materials and constructive solutions. For the aerial noise the research is focused in the porous and fibrous materials. For the attenuation of vibrations the interest is focused in polymeric viscoelastic materials. These polymeric viscoelastic materials are placed on the partition and structural elements to improve the damping and to reduce the vibration levels.
