Abstract
A noise and vibration mitigating mat having top and bottom surfaces comprises a first layer formed of recycled bound rubber product, the first layer having a contoured bottom surface and a generally flat top surface, a second layer on the top surface of the first layer, the second layer being formed of a fabric and a third layer on the second layer and being formed of recycled rubber product.
Claims14
A noise and vibration mitigating mat having top and bottom surfaces comprising:
- a first layer formed of recycled bound rubber product, the first layer having a contoured bottom surface and a generally flat top surface, said contoured bottom surface defining the bottom surface of said mat and having an egg crate configuration defining an array of peaks and valleys, the depth and pitch of the peaks and valleys providing the mat with a selected compression characteristic under load;
- a second layer directly on the top surface of said first layer, the second layer being formed of a fabric;
- and
- a third layer directly on the second layer and being formed of recycled rubber product, said third layer having a generally planar upper surface defining the top surface of said mat.

A noise and vibration mitigating mat comprising:
- a first layer defining having a generally flat top surface and a contoured bottom surface defining a bottom surface of said mat, said contoured bottom surface and having an egg crate configuration defining, an array of peaks and valleys, the depth and pitch of the peaks and valleys providing the mat with a selected compression characteristic under load;
- and
- a second layer overlying the top surface of said first layer and defining a generally flat top surface of said mat, wherein said first and second layers are formed of sound absorbing material so that impact and/or vibration energy applied to said mat is inhibited from propagating to structure surrounding said mat.
