Spring Constant and damping factors for foam rubbers

Spring Constant and damping factors for foam rubbers

(OP)
I am looking to estimate the vibration frequency of an unforced spring-mass-damper system.  Does anyone know a source for spring constants and damping factors for foam rubber?  Preferrable EVA foams?

RE: Spring Constant and damping factors for foam rubbers

Very dependent on the density, and a few other things. Contact the manufacturer if it is an acoustic or vibration related product. They will have measured it, otherwise they won't be able to sell it effectively.
