Bandless hearing protector and method
View Patent ↗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.
1. 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.
2. The hearing protection device of claim 1 further comprising a handle that extends from the shoulder or the neck, wherein the handle does not have a cord member attached thereto.
3. The hearing protection device of claim 1 wherein the first replacement assembly is attached to the positioning member by a hinge.
4. The hearing protection device of claim 1 wherein the first replacement assembly is attached to the positioning member at a fixed angle.
5. The hearing protection device of claim 1 further comprising a stem extending from the first replacement assembly for selectively attaching the positioning member to the first replacement assembly.
6. The hearing protection device of claim 1 further comprising a stem having a stem head, and a boss extending from the stem or stem head, wherein the boss is adapted to engage a slot located in a cavity, and wherein the stem is located on one of the positioning member or the first replacement assembly, and the cavity is located on the other of the positioning member or the first replacement assembly.
7. The hearing protection device of claim 1 wherein the support frame member comprises a plurality of fingers each having a longitudinal axis and arranged in spaced apart configuration such that at the longitudinal axes are parallel or convergent.
8. The hearing protection device of claim 7 wherein the fingers are spaced apart in an oval shape.
9. The hearing protection device of claim 1 wherein the first replacement assembly comprises an EAM pad having a domal shape.
10. The hearing protection device of claim 1 wherein the first replacement assembly comprises an EAM pad having a stepped-domal shape.
11. The hearing protection device of claim 1 wherein the first replacement assembly comprises an EAM pad having a cone shape.
12. The hearing protection device of claim 1 wherein the support frame is permanently affixed to the ear clip.
13. The hearing protection device of claim 1 , further comprising:
a second replacement assembly,
wherein the EAM pad of the first replacement assembly has a first configuration, and the second replacement assembly comprises an EAM pad having a different and second configuration, and wherein the first replacement assembly and the second replacement assembly are configured to be selectively attachable to the positioning member.
14. The hearing protection device of claim 13 further comprising a third replacement assembly having an EAM pad with a different and third configuration.
15. The hearing protection device of claim 13 wherein the first and second replacement assemblies further comprise an anti-rotation stem for connection to the positioning member.
16. The hearing protection device of claim 13 wherein the first and second replacement assemblies differ with respect to the EAM pad length.
17. The hearing protection device of claim 13 wherein the first and second replacement assemblies differ with respect to the EAM pad shape.
18. The hearing protection device of claim 13 wherein the second replacement assembly is connected to the positioning member by a temporary connection selected from the group consisting of: a ball and socket, and a hinge.
19. 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.
20. The passive hearing protection device of claim 19 wherein the plug member comprises an EAM pad.
21. The passive hearing protection device of claim 19 wherein the plug member and the pressure pad are part of a replacement assembly.
