Abstract | |||||||||
| The paper continues the presentation of data describing detection performance in the monaural detection with contralateral cue (MDCC) situation. Subjects detected a monaural sinusoid burst masked by continuous white noise, either with or without an unmasked contralateral cue. The cue, presented in both intervals of each two-interval forced-choice trial, was a sinusoid of the same frequency and duration as the signal, but its phase and intensity were experimentally varied. The main experiment was a factorial study to examine the interactions of frequency, cue phase, and cue intensity. Phase was again found to be important at frequencies below about 1200 Hz, and to be more important the louder the cue. Worst performance at midfrequencies was found for the phase representing a cue lead of about 700 microseconds. The phase and the related interaural time difference giving best performance were functions of both cue intensity and of cue frequency. (Author) | |||||||||
