    Abstract - (Show below) - (Hide below)

    Describes a head and torso simulator for hearing aid measurements. The device is intended for airborne acoustic measurements and is not suitable for measurements which depend on vibration conduction paths such as bone conduction. The head and torso simulator has been designed to provide acoustic diffraction similar to that encountered around the median human head and torso, and as such may be useful for other acoustical measurements. Has the status of a technical report.
