Aufnahme und Wiedergabesystem zur Berechnung eines dynamisch modifizierbaren binauralen Signalpaares
This thesis deals with various methods of 3D – sound reproduction via headphones
with the aim of a recording and reproduction system. Psychoacoustic basics
and fundamental directional hearing mechanisms of the human auditory system
are considered at first. A central point in this context is the importance
of small head movements during localisation of a small sound source in natural
hearing.
Firstly computing binaural signals with beamforming, secondly with Ambisonic
and Holophony is examined.
The advantage of Ambsionic is the possibility to update the headphone signals
according to head position in a computational efficient way. The holophonic
sound pick up is a possibility to obtain the Ambisonic signals from a practical
point of view.
