An earpiece radiation attenuation device that is used to attenuate UHF radiation emitted by an earpiece while the earpiece is being worn in an ear. The earpiece radiation attenuation device has an elastomeric molding that connects to the earpiece emitting the UHF radiation. The elastomeric molding contains metal powder and dielectric material that is homogenously dispersed within a polymer base. The metal powder and dielectric material with the polymer base attenuate UHF radiation in a synergistic manner. The metal powder includes a conductive powder and high-density powder. The conductive powder forms a shield to the UHF radiation. The high-density powder absorbs the UHF radiation. The dielectric material can be glass microspheres that are specifically sized to reflect the UHF radiation, wherein the reflected radiation cancels some of the incoming radiation.

System and method for attenuating radiation emissions from earpiece devices

An earplug device that is placed in the ear canal to attenuate sound frequencies within a selected frequency range. The earplug has a plug body with a first end, an opposite second end, and an exterior surface that extends from the first end to the second end. An opening is formed in the plug body at the first end. The opening leads to an internal conduit within the plug body. The internal conduit terminates at a closed membrane wall proximate the second end of the plug body. The internal conduit and the membrane wall both act upon incoming acoustic signals to both lower volume and attenuate certain undesired frequency ranges.
