Crawford-Emery, Ryan and Lee, Hyunkook (2014) The subjective effect of BRIR length perceived headphone sound externalisation and tonal colouration. In: 136th Audio Engineering Society Convention, 26th-29th April 2014, Berlin, Germany. (Unpublished)

Binaural room impulse responses (BRIRs) of various lengths were convolved with stereophonic audio signals. Listening tests were conducted to assess how the length of BRIRs affected the perceived externalisation effect and tonal colouration of the audio. The results showed statistically significant correlations between BRIR length and both externalisation and tonal colouration. Conclusions are drawn from this and in addition, reasoning, a critical evaluation and suggested further work are suggested. The experiment provides the basis for further development of an effective and efficient externalisation algorithm.
