Abstract

A system for use in connection with a vehicle such as a car provides an indication of an acoustic warning signal originating from a source at a location external to the vehicle such as a horn or a siren from an emergency vehicle. The system comprises a plurality of acoustic detection devices such as microphones for mounting on the vehicle and for detecting the acoustic warning signal to provide respective output signals; and a processing unit for processing the output signals from the acoustic detection devices. The processing unit is arranged to output an indication of the direction, relative to the vehicle, of said location on the basis of a comparison of the respective amplitudes of the acoustic warning signal as detected by the plurality of acoustic detection devices; and/or a comparison of the respective times of arrival of the acoustic warning signal as detected by the plurality of acoustic detection devices.
