A binaural system for the evaluation of sound quality is evaluated and documented in this thesis. The system was developed in the Acoustics Laboratory of the Helsinki University of Technology and it is based on binaural techniques. It consists of tools and methods on how to record, edit using digital signal processing, and present sound samples binaurally to many subjects simultaneously. The tools are evaluated using conventional measurement methods and by listening tests. Also, a technique was developed in this thesis using real (human) heads to make binaural recordings. This is compared to artificial head techniques.
