Abstract
The study measured the detectability of a harmonic tone when presented in conjunction with a contralateral cue. The signal was masked either by wide band noise or by other harmonic tones. In an operational setting, the exact form and frequency of a potential target would not be known. To approximate the signal as closely as possible, with this limitation, the cue was shifted in frequency over its duration from a frequency below the expected frequency of the signal to one above it. Performance was measured with several different forms of cue as well as without it. The detectability of the signal was similar across all conditions. The sliding cue did not appear to provide additional information about the signal to the listeners in the study. It seems even less likely that a cue would be useful in an operational setting.
