2. Systematic evaluation of perceived spatial quality in surround sound systems
Abstract : The aim of this thesis is to elaborate a method for the evaluation of perceived spatial quality in surround systems with emphasis on how to find and validate relevant attribute scales originating from verbal elicitation of personal constructs. The main question raised in this work was: Could a method utilising elicited personal constructs be used for finding a set of attributes with sufficient common meaning, thus enabling a group of experienced listeners to make significant judgements of spatial quality in surround sound systems? To investigate this, a method comprising a number of steps was employed. READ MORE

Abstract : In natural history filmmaking recording fauna vocalisation often produces difficult challenges especially when recording sound from a distance. The camera in many cases is able to solve these problems due to lens changes, but the microphone cannot do this, which creates major problems when combining sound and picture. READ MORE
