Hearing aid extension
Systems and methods are disclosed for enhancing the performance of hearing aids and the like. For example, an extension for a hearing aid can include a stem having one or more flanges formed thereon. The flanges can be configured to enhance the fit of the hearing aid in the ear canal. The extension can cushion sensitive tissues of the ear canal from contact with the hard plastic inner end of the hearing aid. The extension also inhibits undesirable leakage of sound around the hearing aid. Thus, both comfort and effectiveness of a hearing aid or the like are enhanced.
1. An extension for a hearing aid, the extension comprising:
a resilient hollow stem having an outer end configured to receive an inner end of the hearing aid and configured to be inserted into a user's ear canal; and
a strap extending longitudinally from the outer end to form a loop configured to cooperate with the stem to encircle substantially the entire hearing aid to hold the extension onto the hearing aid.
2. The extension as recited in claim 1 , wherein a layer of resilient material defines a stem.
3. The extension as recited in claim 1 , wherein the extension is configured for use with a completely-in-the-ear (CIC) hearing aid.
4. The extension as recited in claim 1 , further comprising a first bore formed through the stem and a plurality of second bores formed generally perpendicularly with respect to the first bore and defining openings formed in the inner end of the extension that are in communication with the first bore.
5. The extension as recited in claim 1 , wherein the stem comprises rubber.
6. The extension as recited in claim 1 , wherein the stem comprises silicone rubber.
7. The extension as recited in claim 1 , wherein the stem has a Shore A durometer of between approximately 35 and approximately 45.
8. The extension as recited in claim 1 , wherein the stem has a Shore A durometer of approximately 40.
9. The extension as recited in claim 1 , further comprising at least one flange formed to the stem.
10. The extension as recited in claim 1 , further comprising at least one flange formed integrally with the stem.
11. The extension as recited in claim 1 , further comprising a plurality of flanges formed to the stem.
12. The extension as recited in claim 1 , wherein the extension is configured to at least partially cover a completely-in-the-ear (CIC) hearing aid.
13. The extension as recited in claim 1 , wherein the stem has a thickness of between approximately 0.001 inch and approximately 0.100 inch.
14. The extension as recited in claim 1 , wherein the stem has a thickness of approximately 0.050 inch.
15. The extension as recited in claim 1 , wherein the stem is curved so as to generally conform to a curvature of the ear canal.
16. The extension as recited in claim 1 , wherein the stem is flesh colored.
17. A hearing aid assembly comprising:
a hearing aid having at least a portion that is configured to be disposed within a user's ear canal; and
an extension attached to the hearing aid, the extension comprising:
a resilient hollow stem having an outer end configured to receive an inner end of the hearing aid and configured to be inserted into a user's ear canal; and
a strap extending longitudinally from the outer end to form a loop configured to cooperate with the stem to encircle substantially the entire hearing aid to hold the extension onto the hearing aid.
18. A completely-in-the-canal (CIC) hearing aid assembly comprising:
a completely-in-the-canal (CIC) hearing aid;
an extension comprising:
a resilient hollow stem having an outer end configured to receive an inner end of the hearing aid and configured to be inserted into a user's ear canal; and
a strap extending longitudinally from the outer end to form a loop configured to cooperate with the stem to encircle substantially the entire hearing aid to hold the extension onto the hearing aid.
19. A method for making an extension for a hearing aid, the method comprising:
injection molding a resilient material so as to form a hollow stem having an outer end that is configured to receive an inner end of the hearing aid;
forming a strap to the resilient material; and
wherein the strap is configured to extend longitudinally from the outer end to cooperate with the stem to encircle substantially the entire hearing aid to attach the extension to the hearing aid.
20. An extension for a wireless receiver, the extension comprising:
a resilient hollow stem having an outer end configured to receive an inner end of the wireless receiver and configured to be inserted into a user's ear canal; and
a strap extending longitudinally from the outer end to form a loop configured to cooperate with the stem to encircle substantially the entire wireless receiver to hold the extension onto the wireless receiver.
21. An extension for an audio device, the extension comprising:
a resilient hollow stem having an outer end configured to receive an inner end of a speaker of the audio device and configured to be inserted into a user's ear canal; and
a strap extending longitudinally from the outer end to form a loop configured to cooperate with the stem to encircle substantially the entire audio device to hold the extension onto the speaker.
22. The extension as recited in claim 21 , wherein the audio device comprises a cellular telephone.
23. The extension as recited in claim 21 , wherein the audio device comprises a music player.
