Primary source abstract:"The just noticeable difference in dichotic phase, as a function of sensation level and of frequency, has been determined on a number of listeners with normal hearing. The test tones were transmitted by earphones, and the phase difference between the ears was varied by means of an electronic phase shifter. The psychophysical method used combined paired comparisons and forced choice. The first tone pulse of each pair presented was kept at a constant phase difference at which the subject localized the sound source as equidistant from his ears. The dichotic phase difference of the second pulse was varied irregularly (“randomly”)." |

p.2839 left column top paragraph:"It is a well-known fact of binaural hearing that human listeners are not able to detect interaural time differences (ITDs) in sine tones with frequencies greater than about 1500 Hz. The standard reference to this fact is an article by Zwislocki and Feldman (primary source). That article reported ITD threshold measurements for three listeners at octave sinetone frequencies, 250, 500, and 1000 Hz, and also at the highest frequency at which data could be obtained, approximately 1300 Hz. The results agreed well with data reported by Klumpp and Eady (1956), which showed an ITD threshold of 24µs at 1300 Hz, but unmeasurably high thresholds at 1500 Hz. Both of these articles found that the lowest threshold ITD, about 10µs, occurred at 1000 Hz, though the frequency resolution of the experiments was course." |
