Developing a behavioural task for measuring the ability of listeners to perform auditory scene analysis. (360G-Wellcome-207256_Z_17_Z)

The auditory brain separates simultaneous sounds arriving at the ear into identifiable and localisable sources by a process known as Auditory Scene Analysis (ASA). The two steps that are involved in ASA are i) segregation of the simultaneous auditory information and ii) the integration of the sounds from the same source into one stream. To understand how these two steps are connected and how different auditory cues interact to shape the scene, this project will develop a behavioural task and analyse the performance of human listeners. A target vowel will be presented alongside with a distractor vowel, and human listeners will identify what the target is. Listeners will only be able to identify the target if they can separate the two sounds: changing the location and pitch of target and distractor will help this. In order find out whether the separation of competing sounds is facilitated by the formation of perceptual streams, the vowels will also be presented as part of a sound sequence. Our hypothesis is that the ability to identify a target vowel will be improved by the formation of two perceptual streams. The long-term goal is to develop a behavioural paradigm suitable for humans and animals.
