Monitoring of acoustical data is often done at fixed measurement stations to verify the compliance with environmental noise or work safety regulations. In this work, a different method is explored for monitoring acoustical conditions in indoor environments with the assistance of location information. Such a method exploits a wideband localization system to determine the listener position with high accuracy, which leads, 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, considering as case study a long partitioned virtual room, where an ultra- wideband (UWB) localization system is used and the subject is moving 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.

Abstract
Monitoring of acoustical data is often done at fixed measurement stations to verify the compliance with environmental noise or work safety regulations. In this work, a different method is explored for monitoring acoustical conditions in indoor environments with the assistance of location information. Such a method exploits a wideband localization system to determine the listener position with high accuracy, which leads, 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, considering as case study a long partitioned virtual room, where an ultra- wideband (UWB) localization system is used and the subject is moving 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.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
