Abstract

The disclosure notably relates to a computer-implemented method for detecting and localizing sirens based on sound signals. Each sound signal represents a sound acquired at a same time frame by a respective microphone of a vehicle. The vehicle comprises at least two microphone modules. Each microphone module comprises several microphones. The method comprises, for each microphone module, by a local processing function, removing noise in the sound signals acquired by the microphones of the module and performing siren detection and localization based on the sound signals acquired by the microphones of the modules. The method further comprises applying a global processing function to the siren detection and localization results outputted by the local processing function for all microphone modules. The global processing function is configured for siren detection and localization based on the results outputted by the local processing function.
