Auditory processing in healthy and pathological conditions

  • Establishing systematic protocols for the assessment of auditory processing from peripheral to central mechanisms.
  • Mechanisms and diagnostics of noise-induced hearing loss and 'hidden' hearing loss.
  • Studying fluctuation in attention as a function of relevant and irrelevant sounds using a free listening electroencephalography (EEG) protocol.
  • Understanding the role of different auditory processing stages for functioning in complex sonic environments.
  • Auditory processing for central auditory processing disorders related with neurological conditions such as Parkinson's disease.
