Abstract: 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.

Abstract: 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.

Abstract: A hearing aid tubing connector for connecting sound conduction tubing from a hearing aid to an earmold and a method for making same wherein the sound conduction tubing extends completely through a bore in the earmold up to the interior opening of the bore near the eardrum. A connector circumferentially attached to the tubing and having a stepped portion engaging the wall of said bore connects in an acoustic seal the tubing to the exterior opening of the bore in the earmold. The tubing extending through the bore in the earmold has an interior diameter which increases between the exterior opening of the bore and the interior opening of the bore. This increase in the tubing may be continuous or stepped. The tubing may be made of PVC and the earmold may be made of silicone.

Abstract: The present invention proves an elbow shaped connector for connecting flexible sound conduction tubing from a hearing aid to a conventional earmold. The sound bore of the connector has an increasing diameter to improve high frequency response. This increase in diameter may be gradual, over the length of the connector, or it may occur abruptly at some point within the connector.
