S Bell 2015 - Personalised fitting & evaluation of hearing aids with EEG responses

Project overview

The project aims to develop algorithms and associated experimental protocols that can be used for personalized hearing aid fitting, based on stimuli that patients consider realistic and challenging. The vision is to reduce the reliance on subjective, voluntary responses, and move to more objective approaches based on neurophysiological responses. Objective approaches have the advantage that they can be carried out in patients who are unable to provide such voluntary responses, for example infants or the elderly with dementia. Also by monitoring hearing without constant interruption to assess patients' perception, the performance of the hearing aid can be assessed in more natural listening conditions and over a longer time scale than is typically available in audiology clinics.

Other researchers

Professor David Simpson

Prof of Biomedical Signal Processing
Research interests
  • Biomedical signal processing with applications in neurophysiology and cardio-vascular and cerebro-vascular control
  • Blood flow control in the brain (how does the brain regulate is own blood supply and how to detect impairment of this function)
  • Auditory evoked potentials (methods to detect the small electrical responses of the brain to auditory stimulation for the assessment of various hearing disorders)
