Just noticeable differences (JND) in ILD were measured in 12 normal hearing subjects for uncorrelated noise bands with a bandwidth of 1\u22153 octave and a different center frequency in both ears. In one ear the center frequency was either 250, 500, 1000, or 4000Hz. In the other ear, a frequency shift of 0, 1\u22156, 1\u22153, or 1 octave was introduced. JNDs in ILD for unshifted, uncorrelated noise bands of 1\u22153 octave width were 2.6, 2.6, 2.5, and 1.4dB for 250, 500, 1000, and 4000Hz, respectively. Averaged over all shifts, JNDs decreased significantly with increasing frequency. For the shifted conditions, JNDs increased significantly with increasing shift. Performance on average worsened by 0.5, 0.9, and 1.5dB for shifts of 1\u22156, 1\u22153, and 1 octave. Though performance decreases, the just noticeable ILDs for the shifted conditions were still in a range usable for lateralization. This has implications for signal processing algorithms for bilateral bimodal hearing instruments and the fitting of bilateral cochlear implants.<\/jats:p>","DOI":"10.1121\/1.2783130","type":"journal-article","created":{"date-parts":[[2008,1,9]],"date-time":"2008-01-09T15:11:21Z","timestamp":1199891481000},"page":"2826-2831","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":40,"title":["Perception of across-frequency interaural level differences"],"prefix":"10.1121","volume":"122","author":[{"given":"Tom","family":"Francart","sequence":"first","affiliation":[{"name":"Katholieke Universiteit Leuven Exp ORL, Dept.
