Surround Sound Systems are designed to faithfully reproduce a movie soundtrack and provide an immersive sound experience to the user, when the loudspeaker placement and the listening position comply with certain standards. Deviation from these standards can cause a distorted or unnatural sound image. In order to address the impact of the loudspeaker setup on the listening experience, two Philips Surround Sound Systems were integrated with Ultra Wideband (UWB) localization technology for the design of two demonstrators. Each demonstrator is composed of two parts; a localization module, providing user’s and speakers’ coordinates and audio tuning algorithms which use this information for the calculations of the signals that are sent to the speakers. In the present study, the performance evaluation of each component as well as the implementation of the demonstrators are described and discussed.
