Auditory Prosthetic Group

Die Auditory Prosthetic Group des Deutschen Hörzentrums, Teil der Medizinischen Hochschule Hannover, forscht auf dem Gebiet der Signalverarbeitung und auditiven Modellierung von implantierbaren Hörprothesen, einschließlich Cochlea-Implantaten und hybriden elektroakustischen Stimulationsgeräten. Die Gruppe ist sehr interdisziplinär und deckt die Bereiche Akustik, Signalverarbeitung, Hörmodelle und Psychophysik ab.

Die Gruppe startete im September 2013 im Rahmen des Exzellenzclusters Hearing4all.

Musik und Cochlea-Implantate

Trennung von Musikquellen mit tiefen neuronalen Netze

Musikbeispiele des Real-time Music Source Separation Experiments. In diesem Experiment wurde ein mehrschichtiges Perzeptron verwendet, um die Gesangsstimme von der instrumentalen Begleitung zu trennen, um den Musiktitel zu remixen. Es hat sich gezeigt, dass CI-Anwender Musik mehr genießen, wenn die Singstimme in Bezug auf die Hintergrundinstrumente verstärkt wird. Unsere Ergebnisse deuten darauf hin, dass CI-Anwender Musik mehr genießen, wenn die Gesangsstimme in Bezug auf die Hintergrundbegleitung um 8 dB verbessert wird.

MusIC: Musik für Anwender von Cochlea-Implantaten zugänglicher machen
  • Verbesserung der Singstimme von Musik zur Verbesserung der Musikwahrnehmung für CI-Benutzer
  • Echtzeit-Trennung von Musikquellen zur Verbesserung der Gesangsstimme
  • Parametrisierung von CI-Soundcodierungsstrategien für Gesangsmusik
  • Sound Coding Strategy für Musik
Music4u
  • Schwierig, komplexe Musik wie z.B. klassische Stücke für CI-Nutzer zu genießen
  • Untersuchung, welche musikalische Komponente (d.h. Melodie) in instrumentaler klassischer Musik CI-Nutzer verbessern wollen
  • Testen, ob eine selektive Aufmerksamkeitsdekodierung für CI-Anwender möglich ist
  • Einspeisung von EEG-Daten in neuronale Netze, um die Quellentrennung der betreuten Schallquelle zu verbessern
