This report describes a head and torso simulator (manikin) which reproduces approximately the acoustical effects of a median human adult, including diffraction affecting the performance of a hearing aid on a person. The device consists of a head mounted on a torso that extends to the waist. The head is equipped with simulated pinnae and with cylindrical cavities having acoustic impedance terminations and microphones located at positions corresponding to those of the eardrums on a medium human adult.
