A system for monitoring an acoustic scene outside a vehicle; the system comprising: a vehicle (1) with wheels (6) and a trunk (3), an acoustic sensor (2) disposed in the trunk (39, a control unit (4) operatively connected to the acoustic sensor (2), and at least one neural network (5) operatively connected to the control unit (4), and trained in such a way to correlate the characteristics of an audio signal with types of road surfaces; the control unit (4) is configured in such a way to receive an audio signal detected by the acoustic sensor (2) while the vehicle is traveling, extract the characteristics of the audio signal and input said characteristics of the audio signal to the neural network (5) in order to identify the type of road surface covered by the vehicle wheels.
