The National Centre for Audiology is an interdisciplinary group of researchers at Western University, housed in the Faculty of Health Sciences with members from many faculties and departments. We seek to understand the hearing system and its disorders, optimize hearing assessment, provide beneficial hearing technologies, support evidence-based, person-centred, and family-centred practices, and develop models and simulations for professional education and practice.
