Research area "Optimized Hearing Devices"

Even though modern conventional (digital) hearing devices use extensive signal-processing adapted to the needs of the hearing impaired individual, substantial research efforts are still needed to restore the individual's hearing capability back to near-normal, in particular for complex listening environments characterized by high levels of noise and reverberation. Restoring normal hearing is the most important goal in developing advanced hearing devices since the ability to communicate with speech and hearing is probably the most important prerequisite in our "communication society". The aim of the research will be to overcome the acoustical problems of conventional hearing aids, to increase the information transmitted via electrical stimulation to the auditory nerve and the central auditory system (in cochlear implants and central auditory implants) and to extract and enhance the relevant acoustical signal characteristics using algorithms prior to presenting the signals using the stimulation device.

Task Groups

  • The Task Group (4) "Algorithms for hearing instruments" will conduct research on the optimal processing schemes for different types of hearing systems and the various acoustic environments.
  • The Task Group (5) "Personalizing hearing devices" focuses on adapting the hearing instrument to the individual patient by forming the link between diagnostics, hearing instrument design, stimulation type and fitting procedures.
