*Bachelor-Lecture*: Sound Source Localization Using Binaural Signals
Binaural signals are similar to the sounds that humans hear with their
left and right ears when the signal is recorded with a suitable device.
As the human auditory system is able to localize sound sources, the
directions of sound sources can also be found in binaural signals.
This thesis addresses the performance of sound source localization
algorithms using binaural signals. The algorithms regarded in this
thesis are based on the concept of beamforming. Several algorithms from
the literature are systematically compared and their basic building
blocks are recombined. From this, a total of 26 variants are identified.
The performance of an algorithm is determined by comparing the accuracy
of the estimated source source’s directions with other algorithms.
Furthermore, error metrics are suggested that take into account the
varying signal powers in different time-frequency bins. According to the
results, there are two algorithms that always estimate the same source
source’s directions and they also provide the most accurate source
source’s directions in most situations.
All interested parties are cordially invited, registration is not required.
