An apparatus and method to attenuate vibration and acoustic noise are provided. One apparatus includes a first layer formed from a non-metal material having a predetermined level of resistance to deformation to define a frequency response based on a vibrating frequency. The non-metal material has a profile defined by at least one sinusoid. The apparatus also includes a second layer defining an absorption layer coupled to the first layer. The second layer adds a body of mass adjacent the first layer.
