Effects of Interaural Decorrelation and Acoustic Spectrum
The ability to detect the motion of an auditory target based on dynamic changes in interaural time differences was measured as a function of interaural correlation and acoustic spectrum in a single-interval forced-choice design. Three subjects listened to headphone-presented noise containing a dynamic linear change in interaural delay (500 μ s/s). The stimulus spectrum was broadband (0.1 to 10 ...
متن کاملEffects of Interaural Decorrelation on Neural and Behavioral Detection of Spatial Cues
The detection of interaural time differences (ITDs) for sound localization critically depends on the similarity between the left and right ear signals (interaural correlation). We show that, like humans, owls can localize phantom sound sources well until the correlation declines to a very low value, below which their performance rapidly deteriorates. Decreasing interaural correlation also cause...
متن کاملInteraural fluctuations and the detection of interaural incoherence: bandwidth effects.
One-hundred left-right noise-pairs were generated, all with a fixed value of long-term interaural coherence, 0.9922. The noises had a center frequency of 500 Hz, a bandwidth of 14 Hz, and a duration of 500 ms. Listeners were required to discriminate between these slightly incoherent noises and diotic noises, with a coherence of 1.0. It was found that the value of interaural coherence itself was...
متن کاملLocal Decorrelation For Improved Detection
Even with the advent of more sophisticated, data-hungry methods, boosted decision trees remain extraordinarily successful for fast rigid object detection, achieving top accuracy on numerous datasets. While effective, most boosted detectors use decision trees with orthogonal (single feature) splits, and the topology of the resulting decision boundary may not be well matched to the natural topolo...
متن کاملDetection of Dynamic Changes in Interaural Delay
The ability to detect a dynamic change in interaural time difference (ITD) was examined for rates of change from 3.125 to 32,000 s/s, for stimulus durations from 0.025 to 16 seconds, and for extent of change in interaural delay from 50 to 800 s. The stimulus was a sinusoidal tone of frequency f Hz presented to one ear and f f to the other ear, where f , the frequency difference, was varied to s...
