U.S. Patent 8,541,496 (September 24, 2013), “Energy Absorbing Composition and Impact and Sound Absorbing Applications thereof,”  Joel Sereboff (Owings Mills, Maryland, USA).

Many materials for dampening sound  are elastic and compressible making them unsuited for many applications.  Sereboff has developed a rigid sound dampener with impact resistance.  Their material is based on a matrix with a phase transition, i.e. solid below a critical force, and liquid above.  This material consists of a polyacrylic acid/glycerin solution containing dispersed mixtures of ceramic microparticles; flexible-walled microparticles, cellular macroparticles and 20 to 80 wt% polyols
