Directional Bands Revisited
Rory Wallis, Hyunkook Lee · University of Huddersfield Repository (University of Huddersfield) · 2015
Listening tests were undertaken as part of a comprehensive analysis of directional bands. The effects of frequency, loudspeaker position, signal duration and bandwidth were all considered. The results confirmed the existence of directional bands for 1,4 and 8 kHz 1/3-octave band bursts. A relationship between pitch and height was also observed. Bandwidth was found to have a variable effect on localisation, depending on frequency, indicating that the spectral cues used in vertical localisation are not of equal bandwidth. Loudspeaker position and signal duration also had some influence on localisation judgments although this was found to be somewhat erratic.
