Abstract
Provided is a method and shield for shielding a behind-the-ear hearing aid. A Mu metal shielding material is bonded to the external or internal surface of the behind-the-ear hearing aid, the shielding providing effective shielding of electromagnetic radiation in the frequency range of 20 Hz to MHz and effective sound shielding in the audio frequency range of 20 Hz to 20,000 Hz. A hearing canal mold comprised of a rubber-like compound, shaped to encompass and seal an outer portion of a hearing tube of a hearing aid and a user's hearing canal entrance is also provided.

A shield for a behind-the-ear hearing aid, the shield comprising a shielding material providing effective shielding of electromagnetic radiation in the frequency range of 20 Hz to 1,600 MHz and effective sound shielding in the audio frequency range of 20 Hz to 20,000 Hz.
A method for shielding a behind-the-ear hearing aid, the method comprising encompassing the electromagnetic, radio and sound wave producing components with a shielding material providing effective shielding of electromagnetic radiation in the frequency range of 20 Hz to 1,600 MHz and effective sound shielding in the audio frequency range of 20 Hz to 20,000 Hz.
A kit for shielding a behind-the-ear hearing aid, the kit comprising:
- a shielding material for providing effective shielding of electromagnetic radiation in the frequency range of 20 Hz to 1,600 MHz and effective sound shielding in the audio frequency range of 20 Hz to 20,000 Hz when installed;
- an adhesive for bonding the shielding material to an outer surface of the behind-the-ear hearing aid;
- a hearing canal mold, wherein the hearing canal mould is comprised of a rubber-like silicone compound, and the hearing canal mold further comprises an inner surface shaped to encompass and seal an outer portion of a hearing tube of the hearing aid and an outer portion shaped to encompass and seal a user's hearing canal entrance;
- and
- instructions for installing the shielding material on the behind-the-ear hearing aid and for installing the hearing canal mold.
A kit for shielding a behind-the-ear hearing aid, the kit comprising:
- two or more preformed and annealed sections comprised of a shielding material for providing effective shielding of electromagnetic radiation in the frequency range of 20 Hz to 1,600 MHz and effective sound shielding in the audio frequency range of 20 Hz to 20,000 Hz when installed, the two or more sections being joined to form a containment around a behind-the ear-hearing aid;
- a hearing canal mold, wherein the hearing canal mould is comprised of a rubber-like silicone compound, and the hearing canal mold further comprises an inner surface shaped to encompass and seal an outer portion of a hearing tube of the hearing aid and an outer portion shaped to encompass and seal a user's hearing canal entrance;
- and
- a fastening means for securing the two or more joined sections to one another.
A shield for a behind-the-ear hearing aid, the shield comprising a Mu metal shielding material bonded to the external surface of the behind-the-ear hearing aid, the shielding providing effective shielding of electromagnetic radiation in the frequency range of 20 Hz to 1,600 MHz and effective sound shielding in the audio frequency range of 20 Hz to 20,000 Hz.
