Download Issues in Performance Prediction of Surround Systems for Sound Reinforcement Applications
Multichannel audio is set to change the way we listen to reproduced music, allowing the creation of spatial auditory images that will add, quite literally, more dimensions to the whole listening experience Current methods for the objective assessment of the imaging imparted by holographic sound systems assume listening conditions that can be met exclusively in household installations, where the audience is usually located in a very restricted area and the acoustical properties of the room can be generally neglected. In this paper we address the main limitations of these traditional evaluation techniques in the instance of surround sound systems serving large and acoustically non-ideal listening areas.
