Abstract

See full text

A hearing aid includes a magnetic sensor to sense a sound signal being a magnetic field. The magnetic sensor includes a telecoil to sensor the sound signal and a counter coil to cancel a noise signal resulting from electromagnetic interference. In one embodiment, a driver circuit for the counter coil allows for automatic adjustment of the hearing aid circuit for an interference null.
