Abstract
This thesis investigates how the audio quality in a door station can be improved
by using multiple microphones and implementing beamforming. The concept of
beamforming is explained, and two beamforming algorithms are implemented.
These are tested with different microphone configurations in both simulated and
real environments. Three already implemented solutions for single microphones
are also tested.
The performance of different microphone configurations is analysed, and the
beamforming algorithms are compared to the single microphone solutions. Finally
a solution for the application is proposed.
