“Auditory perception and recognition of environmental sounds”.
During this INT/CONECT seminar, Prof. Laurie M. Heller will present her research on the auditory perception and recognition of environmental sounds “Auditory perception and recognition of environmental sounds”
Abstract : Our sense of hearing informs us about events and environments around us. The sounds we hear are shaped by the forces, actions, objects, and substances that generate them. There is evidence that humans have explicit access to physical causal properties of sound-generating events and can implicitly use acoustic properties to organize and understand sound events. This talk reviews a series of studies showing ways in which causal properties, such as the causal actions (e.g. bouncing, dripping), are relevant and useful concepts. Misidentification of sounds can help inform us about the sound recognition process and can also be used to promote cognitive reappraisal and tolerance of unpleasant sounds. Different types of causal properties undergo differential neural processing. Causal properties are relevant to synthesizing sounds that transition between sound categories, identifying spectro-temporal features supporting recognition, revealing the most rapid and accurate level of sound description, improving automatic classification of sound events, understanding misidentification patterns in normal and impaired hearing, sound pleasantness, and multimodal integration.
