Interested persons can check out the announcement on the Frontier'= s website under the research topic "Probing Auditory Scene Analysis". Below= is a basic description. Best, Elyse ---------------------------------------------------------------------------= ----- Frontiers in Auditory Cognitive Neuroscience Topic Title Probing auditory scene analysis Topic Editor (s) Elyse Sussman, Susan Denham, Susann Deike Suggested By Susann Deike Suggested On 25 Feb 2013 Topic Description In natural environments, the auditory system is typically confronted with a= mixture of sounds originating from different sound sources. As sounds spre= ad over time, the auditory system has to continuously decompose competing s= ounds into distinct meaningful auditory objects or "auditory streams" refer= ring to certain sound sources. This decomposition work, which was termed by= Albert Bregman as "Auditory scene analysis" (ASA), involves two kinds of g= rouping to be done. Grouping based on simultaneous cues, such as harmonicit= y and on sequential cues, such as similarity in acoustic features over time= . Understanding how the brain solves these tasks is a fundamental challenge= facing auditory scientist. In recent years, the topic of ASA was broadly i= nvestigated in different fields of auditory research, including a wide rang= e of methods, studies in different species, and modeling. Despite the advan= ce in understanding ASA, it still proves to be a major challenge for audito= ry research. This includes verifying whether experimental findings are tran= sferable to more realistic auditory scenes. A central approach in understanding ASA is the use of certain stimulus para= meters that produce an ambiguous percept. The advantage of such an approach= is that different perceptual organizations can be studied without varying = physical stimulus parameters. Additionally, the perception of ambiguous sti= muli can be volitionally controlled by intention or task. By using this one= can mirror real hearing situations where listeners intent to identify and = to localize auditory sources. Recently it was also found that in classical = auditory streaming sequences perceptual ambiguity was not restricted to but= was observed over a broad range of stimulus parameters. The proposed Research Topic pursues to bring together scientist in the diff= erent fields of auditory research whose work addresses the issue of percept= ual ambiguity. Researchers are welcome to contribute experimental reports, = computational modeling, and reviews that consider auditory ambiguity in its= modality specific characteristics as well as in comparison to visual ambig= uous figures. The overall goal of contributions should be to consider the e= xperimental findings from the perspective of real auditory scenes. In a bro= ader sense, the Research Topic is open for contributions which are related = to the issue of active listening in complex scenes.
