Gaps-in-noise: a silent window into how the brain processes sound
Abstract: Listening to a conversation in noise, a conversation over a cellphone with poor quality audio, or a person with a heavy foreign accent are all circumstances that are challenging for a person with poor temporal processing. Temporal processing is the ability to hear silent periods in sound. Being able to distinguish silent periods in sound are an essential part of healthy hearing and not something we can remedy with amplification alone. In this presentation I will show work from my lab over the last few years that demonstrate how the auditory cortex responds to the onset of a silent pause (i.e. a gap) in noise using electroencephalography (EEG) and discuss populations with hearing loss that have known changes in their gap-EEG response. We will also discuss what this means in terms of future work and new potential avenues for clinical intervention.
Bio: Dr. Victoria Duda is an Assistant Professor at the School of Speech-Language Pathology and Audiology at the Université de Montréal and research director of the CATLab. She has a master’s degree in Audiology and a Ph.D. in Rehabilitation Sciences from the University of Ottawa. Her work builds on the framework of patient-partnership research which promotes the inclusion of patient-lived experiences in the co-construction of audiological intervention plans. Her research centers around the theme of developing new clinical diagnostic tools, techniques and assistive devices to improve the function of the auditory system and provide accessibility to those with various types of a range of hearing loss. She currently works with problems touching populations with deaf blindness and with functional hearing difficulties such as tinnitus, hyperacusis and auditory dyssynchrony.
Dre Victoria Duda est professeure adjointe à l’École d’orthophonie et d’audiologie de l’Université de Montréal et directrice de recherche du CATLab. Elle est titulaire d’une maîtrise en audiologie et d’un doctorat en sciences de la réadaptation de l’Université d’Ottawa. Son travail s’appuie sur le cadre de recherche patient-partenaire qui favorise l’inclusion des expériences vécues par les patients dans la co-construction des plans d’intervention audiologique. Ses recherches s’articulent autour du thème du développement de nouveaux outils de diagnostic clinique, de nouvelles techniques et de nouveaux appareils de suppléance auditives pour améliorer le fonctionnement du système auditif et offrir un accès aux personnes souffrant de divers types de déficience auditive. Elle travaille actuellement sur des problèmes qui touchent des populations atteintes de surdicécité et de troubles auditifs fonctionnels tels que les acouphènes, l’hyperacousie et la dyssynchronie auditive.
