Activities

Centre for persons with tinnitus and vestibular disorders is a clinical Unit as a part of Center of Excellence activities. The Unit's objective is to bridge the gap between the need and availability of professionals for assessing and rehabilitating persons with Tinnitus and Vestibular disorders. Hence, the emphasis will mainly be on providing the following:

State-of-the-art hands-on training for stakeholders on Tinnitus, hyperacusis, and vestibular assessment and management
State-of-the-art clinical services to individuals with Tinnitus, hyperacusis and Vestibular disorders
