Loudspeaker Positions with Sufficient Natural Channel Separation for Binaural Reproduction

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Natural channel separation describes the channel separation produced prior to the implementation of crosstalk cancellation. Sufficient channel separation must exist for successful binaural reproduction. To the authors’ knowledge, an investigation into source positions which inherently produce this value has not been completed. The transfer functions of 655,214 loudspeaker positions were simulated using the boundary element method and the natural channel separation calculated for each. For loudspeaker positions under 0:5m from the head, there is a clear inverse relationship between NCS and distance. Close to the head, many positions exceed the 20 dB channel separation needed. Results suggest that near-field binaural reproduction may be implemented without crosstalk cancellation, subject to further perceptual testing.
