This paper makes an analysis of the different methods of acoustic source localization and proposes a simple and versatile solution which can be very easily implemented in an urban environment. The electronic equipment advanced here will allow the fast detection and localization of powerful noises associated to violent accidents such as gunfire, explosion, collapse, collision, etc. which endanger human life or material goods. An assembly of minimum four acoustic sensors (for localization in small and medium urban area) allows the detection of the triggering of the same powerful sound at close time intervals. The absolute time differences sent by each detector on a dedicated frequency band to a central unit of data processing permit the determination of the coordinates of the noise source. The localization error will be analyzed for several configurations of the sensor network. Because the aim of this project is a civilian one, we will discuss the capability of the system to get the data and to announce as quickly as possible the police, firemen or rescue teams about the location where one of the above mentioned events started.
