Verhulst group

Prof. Dr. Sarah Verhulst

Research Interests

  • Sound encoding in the normal and impaired auditory system
  • Understanding the interplay between different pathologies
  • Developing diagnostic methods to improve individual characterization of hearing loss

Approach

  • Combining non-objective measures such as otoacoustic emissions (OAEs) and EEG with psychoacoustic outcome measures
  • Using computational models of the auditory periphery to understand the underlying mechanisms and test OAE/EEG predictions for different pathologies.
