Abstract: A system and method for testing and measuring hearing assistance device s using a plane wave tube is provided. One aspect of this disclosure relates t o a method for testing a hearing assistance device. According to an embodiment, the hearing assistance device is mounted proximal to an acoustic waveguide havin g a soundfield with acoustic waves propagating down the waveguide. A microphone of the hearing assistance device is placed in the soundfield of the acoustic waveguide to increase a direct acoustic component and to reduce reflected acoustic components and scattered acoustic components of sound sensed by the microphone. Sound i s generated using a sound generator to propagate sound of desired frequencies down the waveguide. Other aspects and embodiments are provided herein.
