Abstract
A dummy head for use in recording binaural sounds includes a pick-up for the sounds in the form of two microphones. The head comprises a pair of simulated ears, each having a single smooth three-dimensional, curved surface extending radially in all directions so the inner surface of an auditory canal is continuous with the curved surface and the junction area between them is smoothly curved, to improve the frequency characteristics of the output signals of the microphones. The microphone is located in each ear.
