A hearing aid switch utilizes pressure/sound clues from a filtered input signal to enable actuation initiated by a user by a signature hand movement relative to a wearer's ear. The preferred signature hand movement involves patting on the ear meatus at least one time to generate a compression wave commonly thought of as a soft “clap” or “pop”. A digital signal processor analyzes the signal looking for a negative pulse, a positive pulse, and dissipation of the hand generated signal.
