“…We used an objective measure of stream segregation adapted from the RMR procedure that was described by Turgeon and colleagues (2002) for sound sequences that were distinguished by center frequency and by Sach and Bailey (2004) for sequences of 500-Hz tones that were distinguished by interaural difference. In our study, sound sequences were distinguished by source location or by interaural difference.…”

“…We adapted the "rhythmic masking release" procedure that has been described by Turgeon and colleagues (2002) and by Sach and Bailey (2004). In our version of the procedure, the listener was required to discriminate between two temporal patterns ("rhythms") carried by sequences of brief noise bursts presented from a free-field sound source (the "target").…”

Spatial hearing is widely regarded as helpful in recognizing a sound amid other competing sounds. It is a matter of debate, however, whether spatial cues contribute to "stream segregation," which refers to the specific task of assigning multiple interleaved sequences of sounds to their respective sources. The present study employed "rhythmic masking release" as a measure of the spatial acuity of stream segregation. Listeners discriminated between rhythms of noise-burst sequences presented from free-field targets in the presence of interleaved maskers that varied in location. For broadband sounds in the horizontal plane, target-masker separations of !8 permitted rhythm discrimination with d 0 ! 1; in some cases, such thresholds approached listeners' minimum audible angles. Thresholds were the same for low-frequency sounds but were substantially wider for high-frequency sounds, suggesting that interaural delays provided higher spatial acuity in this task than did interaural level differences. In the vertical midline, performance varied dramatically as a function of noise-burst duration with median thresholds ranging from >30 for 10-ms bursts to 7.1 for 40-ms bursts. A marked dissociation between minimum audible angles and masking release thresholds across the various pass-band and burst-duration conditions suggests that location discrimination and spatial stream segregation are mediated by distinct auditory mechanisms.

“…For instance, spatial auditory cues have a relatively weak influence over local time scales [13,14]. However, perceived location (as opposed to basic spatial cues such as interaural time differences [15]) strongly influences how we link short-term auditory objects into a coherent stream [16].…”

Theories of visual attention argue that attention operates on perceptual objects, and thus that interactions between object formation and selective attention determine how competing sources interfere with perception. In auditory perception, theories of attention are less mature, and no comprehensive framework exists to explain how attention influences perceptual abilities. However, the same principles that govern visual perception can explain many seemingly disparate auditory phenomena. In particular, many recent studies of "informational masking" can be explained by failures of either auditory object formation or auditory object selection. This similarity suggests that the same neural mechanisms control attention and influence perception across different sensory modalities.

A sequence of sounds may be heard as coming from a single source (called fusion or coherence) or from two or more sources (called fission or stream segregation). Each perceived source is called a ‘stream’. When the differences between successive sounds are very large, fission nearly always occurs, whereas when the differences are very small, fusion nearly always occurs. When the differences are intermediate in size, the percept often ‘flips’ between one stream and multiple streams, a property called ‘bistability’. The flips do not generally occur regularly in time. The tendency to hear two streams builds up over time, but can be partially or completely reset by a sudden change in the properties of the sequence or by switches in attention. Stream formation depends partly on the extent to which successive sounds excite different ‘channels’ in the peripheral auditory system. However, other factors can play a strong role; multiple streams may be heard when successive sounds are presented to the same ear and have essentially identical excitation patterns in the cochlea. Differences between successive sounds in temporal envelope, fundamental frequency, phase spectrum and lateralization can all induce a percept of multiple streams. Regularities in the temporal pattern of elements within a stream can help in stabilizing that stream.
