Abstract
This paper deals with the use of linear microphone arrays for detection and localization of acoustic events in real noisy environment. During the ESPRIT project DIMUS (ESPRIT 5345) a prototype was developed that provided high performance in a demonstration room. The envisaged application is an acoustic surveillance system to be installed in an underground station (DIMUS project ESPRIT 5345). For this purpose, some scenarios were defined in a real station and some preliminary experiments were conducted to verify system robustness. The results show satisfactory performance in detecting and localizing impulsive events (e.g. explosions), while there is a slight drawback for other events (e.g. screams). Due to this, further study is needed concerning the system adaptation to real environment, characterized by critical noise and reverberation components.
