Magnetically controllable hearing aid

A magnetically controlled hearing aid comprising:

• a) a microphone for generating electrical signals from acoustical input;
• b) a single magnetic switch actuatable by the presence of a magnetic field and deactuatable by the removal of the magnetic field;
• c) an output transducer earphone for transforming processed electrical signals into a user compatible form;
• and
• d) hearing aid circuitry connected to the microphone, the output transducer, and the magnetic switch, the hearing aid circuitry comprising signal processing circuitry and control processing circuitry for controlling the signal processing circuitry, the signal processing circuitry configured for processing said electrical signals generated by the microphone, the signal processing circuitry including an adjustable operational parameter, said adjustable operational parameter having a minimum setting, a plurality of mid-range settings and a maximum setting and wherein the control processing circuitry is configured to repeatedly cycle through said minimum setting, said plurality of mid-range settings and said maximum settings exclusively by actuation of said single magnetic switch whereby a desired setting may be selected, changed, and reselected solely by operation of said single magnetic switch.
