A substantially non-elastic incompressible composition, which substantially does not quickly self-level under standard operating conditions, includes: a suspending agent which reacts substantially as a solid when subjected to forces below a critical force, and which becomes substantially flowable when subjected to forces above said critical force; ceramic microparticulates dispersed within the suspending agent; flexible-walled microparticulates dispersed within the suspending agent; and celled macroparticulates dispersed within the suspending agent. The composition provides an incident energy absorbing property. The incident energy may include sound energy, and the microparticulates and macroparticulates may convert some of the sound energy into heat, or may diffract the sound energy.
