1. An In The Ear, All in The Ear, In The Canal or Completely In The Canal hearing aid comprising:
- a case, internal components, a battery door, a battery, a microphone, a speaker a volume control, a telephone coil activation switch, a telephone coil, and internal wires;
the internal wires are made resistant to electromagnetic interference produced by cellular telephones in the 800 MHz to 100 GHz frequency range by lining the case with an electrically conductive material;
one or more inductors or ferrite devices are put in series with some of the internal wires or components;
one or more capacitors are put in parallel with some of the internal wires or components;
the internal components arc shielded from electromagnetic interference with electrically conductive foil, and conductive gaskets;
the case of the hearing aid further comprising a face plate and shell, said face plate and shell being made of or covered by an electrically conductive material, said face plate and shell being bonded together both electrically and mechanically in such a way that none of the conductive material comes in contact with the ear when the hearing aid is worn, and said face plate having said battery door made entirely or partially of conductive material, and said battery door being covered by a disposable strip of conductive tape, and said conductive tape having a conductive adhesive.

Abstract
A Behind The Ear, In The Ear, All in The Ear, In The Canal, or Completely In The Canal hearing aid which is made resistant to electromagnetic interference produced by cellular telephones in the 800 MHz to 100 GHz frequency range. The resultant hearing aid will allow hearing impaired people to take advantage of cellular telephones and other recently-developed personal communication devices while also using their hearing aids.
