Stream segregation is the process by which the auditory system disentangles the mixture of sound inputs into discrete sources that cohere across time. The length of time required for this to occur is termed the "buildup" period. In the current study, we used the buildup period as an index of how quickly sounds are segregated into constituent parts. Specifically, we tested the hypothesis that st...

Parsing of information from the world into objects and events occurs in both the visual and auditory modalities. It has been suggested that visual and auditory scene perception involve similar principles of perceptual organization. This study investigated cross-modal scene perception by determining whether an auditory stimulus could facilitate visual object segregation. Specifically, we examine...

Spatial release from masking (SRM) occurs when spatial separation between a signal and masker decreases masked thresholds. The mechanically-coupled ears of Ormia ochracea are specialized for hyperacute directional hearing, but the possible role of SRM, or whether such specializations exhibit limitations for sound source segregation, is unknown. We recorded phonotaxis to a cricket song masked by...

A key problem in computational auditory scene analysis (CASA) is monaural speech segregation, which has proven to be very challenging. For monaural mixtures, one can only utilize the intrinsic properties of speech or interference to segregate target speech from background noise. Ideal binary mask (IBM) has been proposed as a main goal of sound segregation in CASA and has led to substantial impr...
