Pure-Tone Cross-Ear Localization Effects
Willard R. Thurlow, Lloyd F. Elfner · The Journal of the Acoustical Society of America · 1959
Experiments are reported on the effect of a tone in one ear on the localization of a tone in the other ear. Localization effects were systematically explored with low frequencies at 30-db sensation level, the frequency in one ear being a simple n/1 multiple of that in the other. With this procedure, localization effects can be obtained between low-frequency tones (below 1000 cps) of widely differing frequencies. If multiples are not used, localization effects occur only within narrower frequency limits for low frequencies. Thresholds for difference between the frequencies in the two ears within which the localization effect occurs increase systematically as one goes from low- to high-frequency regions. The localization effects on a given tone cause this tone to be perceived as “pulled in” from the side location that it had when sounded alone.
