Claims21
A sound absorbing device of the type adapted to cover the ears of a user and comprising a sound absorbing material contained within a container in the form of a cellular scaffold, wherein the sound absorbing material comprises of a thixotropic material which is located in the cells of the cellular scaffold.
(canceled)
A method of protecting an ear from high intensity noise comprising the step of placing a sound absorbing device of the type adapted to cover the ears of a user and comprising a sound absorbing material contained within a container in the form of a cellular scaffold, wherein the sound absorbing material comprises of a thixotropic material which is located in the cells of the cellular scaffold over the ear, wherein the thixotropic material has a resting viscosity which exhibits low resistance to passage of low intensity noise, and wherein the thixotropic material decreases in viscosity in response to incident high intensity noises to thereby exhibit high resistance to the high intensity noise.
