A hearing aid is an electro acoustic device which typically fits in or behind the wearer's ear, and is designed to amplify and modulate sound for the wearer. Earlier devices, known as "ear trumpets" or "ear horns" were passive funnel-like amplification cones designed to gather sound energy and direct it into the ear canal.
