Abstract: Natural channel separation (NCS) refers to the level of acoustic isolation which exists naturally between the ears for a single sound source. To the authors’ knowledge, no systematic study has been undertaken to identify source positions which can produce the required level of NCS for binaural reproduction to be achieved without using crosstalk cancellation. The transfer functions of 655,214 loudspeaker positions were simulated using the boundary element method and the NCS calculated for each. For loudspeaker positions under 0.5 m from the head there is a clear inverse relationship between NCS and distance. Close to the head, many positions exceed the 20 dB NCS required. Results suggest that near-field binaural reproduction may be implemented without crosstalk cancellation, subject to further perceptual testing.

AB - Natural channel separation (NCS) refers to the level of acoustic isolation which exists naturally between the ears for a single sound source. To the authors’ knowledge, no systematic study has been undertaken to identify source positions which can produce the required level of NCS for binaural reproduction to be achieved without using crosstalk cancellation. The transfer functions of 655,214 loudspeaker positions were simulated using the boundary element method and the NCS calculated for each. For loudspeaker positions under 0.5 m from the head there is a clear inverse relationship between NCS and distance. Close to the head, many positions exceed the 20 dB NCS required. Results suggest that near-field binaural reproduction may be implemented without crosstalk cancellation, subject to further perceptual testing.
