Abstract
A hearing aid includes at least one capacitive switch for controlling or communicating with the hearing aid by touch. The capacitive switch is an electrode on the inside of the housing coupled to a touch detector. Touching the outside of the hearing aid adjacent the electrode produces a switching operation. The hearing aid includes a programmed microprocessor coupled to the touch detector. The microprocessor is programmed to effect predetermined functions in response to particular touch patterns.
