Abstract: An improved in-the-ear hearing aid. The earmold is divided into two separate chambers defined by a divider wall. A first chamber has an opening adjacent the outer ear and the second chamber has an opening adjacent the ear drum. A microphone is positioned adjacent the first chamber opening. An amplifier and a battery for its power source are located within the first chamber. A receiver with a sound emitting aperture is located within the second chamber. The sound emitting aperture is directed toward the divider wall. The receiver is completely surrounded by an acoustic resistance material which separates the receiver from the walls of the chamber. The microphone, amplifier, battery and receiver are electrically interconnected for supplying to the receiver amplified microphone signals. The combination of the dimensions of the chamber and the acoustic material provide a horn effect to the receiver produced sound. The opening of the second chamber may be covered with a removable grill.
