It is known that headphone playback, even of binaurally-recorded material, often gives rise to in-the-head locatedness of reproduced sound sources. Head-tracking systems, artificial reverberation, and decorrelation of the left/right signals, have all been investigated previously as possible means by which the incidence of in-the-head locatedness may be reduced. It is proposed that the left/right symmetry of dummy-head pinnae, and of the head-related transfer functions used in binaural convolution, may exacerbate the in-the-head problem, and it is shown experimentally that, by recording using asymmetrical pinnae, perceived externalisation can be increased significantly.
