Abstract
A hearing protection device and method of use intended for a human ear. A plug member caps or enters ear canal, and may be shaped to conform to the external auditory meatus. The plug member may be part of a replacement assembly. The device is biased at least in part by a pressure pad to provide some force against the plug member. An optional handle may be provided to assist with temporarily pulling the plug member away from the ear canal or providing adjustment. An optional bow member clips about the pinna. The device may be adapted for use as an ear phone.
Claims21
A hearing protection device for the passive attenuation of sound at a single human ear canal, the device comprising:
- a first replacement assembly comprising an EAM pad that is integrally connected to a pressure pad, wherein the pressure pad fits into a cavum conchae region of the human ear, and a support frame;
- and
- a positioning member that assists with disposing at least a portion of the EAM into the ear canal, the positioning member defined by an ear clip comprising a neck, a shoulder, and an arm.
A hearing protection device adapted to fit a human ear canal comprising:
- a plug member, wherein the plug member passively attenuates sound and is attached to a positioning member, the positioning member being defined by an ear clip comprising a neck, a shoulder and an arm;
- and
- a pressure pad that is attached to the positioning member or the plug member, wherein the pressure pad fits into a cavum conchae region of the human ear;
- wherein the positioning member is adapted to make contact with an ear structure near the human ear canal to limit how far the plug member may enter into the human ear canal when the hearing protection device is positioned to effectively attenuate sound in the human ear to a desired attenuation level.
