Angular Resolution Requirements for Binaural Room Scanning

Binaural Room Scanning is a method of capturing and reproducing a binaural representation of a room or car, using a dummy head incorporating binaural microphones, and individual measurements made with the dummy head positioned at a number of different head angles. The measurement process can be time-consuming. It is therefore important to know how high the angular resolution needs to be. An experiment was performed to see if the angular resolution could be reduced from the current one degree resolution to 15 degree resolution, without causing an audible difference. Using a three alternative forced choice method, trained listeners compared one degree and 15 degree angular resolution, and could not reliably detect the difference.
