Spatial Release from Masking for Tones and Noises in a Soundfield under Conditions Where Targets and Maskers Are Stationary or Moving
Stationary visual targets often become far more salient when they move against an otherwise static background–the so-called “pop out” effect. In two experiments conducted over loudspeakers, we tested for a similar pop-out effect in the auditory domain. Tone-in-noise and noise-in-noise detection thre...

description | Stationary visual targets often become far more salient when they move against an otherwise static background–the so-called “pop out” effect. In two experiments conducted over loudspeakers, we tested for a similar pop-out effect in the auditory domain. Tone-in-noise and noise-in-noise detection thresholds were measured using a 2-up, 1-down adaptive procedure under conditions where target and masker(s) were presented from the same or different locations and when the target was stationary or moved via amplitude-panning. In the first experiment, target tones of 0.5 kHz and 4 kHz were tested, maskers (2–4, depending on the condition) were independent Gaussian noises, and all stimuli were 500-ms duration. In the second experiment, a single pink noise masker (0.3–12 kHz) was presented with a single target at one of four bandwidths (0.3–0.6 kHz, 3–6 kHz, 6–12 kHz, 0.3–12 kHz) under conditions where target and masker were presented from the same or different locations and where the target moved or not. The results of both experiments failed to show a decrease in detection thresholds resulting from movement of the target. |
