Abstract:
Monitoring of acoustical data is often done outdoor at fixed measurement stations to verify the compliance with environmental noise regulations. A different paradigm is applied indoor, where collection of acoustical data is done by sensing units worn by moving persons to measure directly at the receiver. In this work, a different method is explored for monitoring acoustical conditions in indoor environments with the assistance of location information. Such method exploits a wideband localization system to determine the listener position with high accuracy, which serve, together with prior knowledge of the sound field, to assess the behaviour of the local acoustical data in the indoor environment. An application of this method is developed for the case study of a long partitioned virtual room, in which an ultra-wideband (UWB) localization system is used and the subject moves along a trajectory characterized by abrupt acoustical changes. First, the behaviour of various acoustical metrics is assessed along the trajectory. Then, the perspectives of this monitoring method are outlined and discussed.
