Monaural localization of low‐pass noise bands in the horizontal plane

Monaural localization of low‐pass noise positioned in the horizontal plane on the side of the unoccluded ear was investigated. Listeners showed no localizing ability until the upper cutoff frequency of the noise was advanced to 5.0 kHz. Performance proficiency increased progressively with the inclusion of still higher audio frequencies. Consonant with the behavioral data were the results of sound spectrum measurements performed on a head–pinna model. The spectral composition of a broad‐band noise positioned at various azimuthal positions became clearly distinguishable, one from another, only at the higher frequencies.Subject Classification: 65.62, 65.75, 65.54.
