Effect of Pressure on the Static and Dynamic Acoustic Properties of Porous Rubber,
Abstract
In this report we analyze the effects of pressure on the acoustic properties of porous rubbers. We consider the static and dynamic bulk moduli, the velocities of dilatational and shear waves, the characteristic wave impedances, the fundamental frequency of the monopole resonance, and the frequency dependence of the effective sound speed and attenuation. A series of figures at the end of the report shows how the (static) acoustic properties vary with pressure, and how the dynamic properties of the composite are altered by added pressures as high as 400 psi.
