Title / Titel Hearing instrument algorithms for improved spatial perception
PDF Abstract (PDF, 14 KB)
Summary / Zusammenfassung Traditionally, hearing aids process sound signals independently for the two ears and therefore do not take into account the specific interaural level (ILD) and time difference (ITD) cues which result from the geometry of the head and body of the hearing aid wearer in respect to the position of the sound sources. Bidirectional signal transmission in audio quality has recently become available in hearing aid technology which opens new possibilities for true binaural signal processing. The application of binaural cue detection in realistic acoustic environments with reverberation and moving multiple sources poses a number of challenging problems for which new solutions are being sought. The evaluation of algorithmic implementations are performed using simulated rooms and head related transfer functions as well as listening experiments with experimental subjects in real rooms.
