Abstract:
Methods and apparatus for a hearing aid include a mechanism to detect the presence of a magnetic field using a magnetic sensing device disposed in a hearing aid, to digitally modify a frequency response of the hearing aid in response to the detection of the presence, and to modify the frequency response of the hearing aid in response to the magnetic sensing device determining removal of the magnetic field.
