INTRODUCTION OF THE LABORATORY

The main focus of the Audio-Video Research Laboratory includes applied research and measurements on the field of acoustics, image processing and virtual reality. A semi-anechoic (sound proof) chamber for dedicated measurements and sound recording purposes is also available.
