Abstract: An apparatus for and method of employing an electronic hearing aid device to assist a hearing impaired patient. The resonance curve of the outer auditory canal of the patient is determined. A device in accordance with the present invention is tuned to a frequency response curve which matches the measured resonance curve. The device is tuned by adjusting the overshoot of a low pass filter stage which is interposed between the microphone input and a class D output stage.

Abstract: A hearing aid is provided with a switch that automatically, non-manuall y switches at least one of inputs, filters, or programmable parameters in the presence of a magnetic field. The magnetic field can be generated by a magnet in a telepho ne handset. The hearing aid further is programmed based on time-varying characteristics of the magnetic field. Wireless activation or deactivation of the hearing aid is also described. A magnetic field dependant switch turns the hearing aid on or off.
