Abstract

Un dispositif de traitement (1) équipe un véhicule (2) comprenant un habitacle (3), et comprend : - un premier microphone (4) installé à l’intérieur de l’habitacle (3) et convertissant des premières ondes sonores présentes dans ce dernier (3) en des premiers signaux électriques, - un second microphone (5) installé à l’extérieur de l’habitacle (3) et convertissant des deuxièmes ondes sonores présentes à l’extérieur en des deuxièmes signaux électriques, et - un premier processeur (6) installé dans le véhicule (2) et appliquant aux deuxièmes signaux électriques une fonction de transfert représentative d’une modification subie par des ondes sonores lors de l’entrée dans l’habitacle (3) afin de déterminer des troisièmes signaux électriques, puis soustrayant ces derniers des premiers signaux électriques afin de déterminer des quatrièmes signaux électriques représentatifs de troisièmes ondes sonores produites dans le véhicule (2) et entendues dans l’habitacle (3). Figure à publier avec l’abrégé : Fig. 1A processing device (1) equips a vehicle (2) comprising a passenger compartment (3), and comprises: - a first microphone (4) installed inside the passenger compartment (3) and converting first sound waves present in the latter (3) into first electrical signals, - a second microphone (5) installed outside the passenger compartment (3) and converting second sound waves present outside into second electrical signals, and - a first processor (6) installed in the vehicle (2) and applying to the second electrical signals a transfer function representative of a modification undergone by the sound waves when entering the passenger compartment (3) in order to determine third signals electrical signals, then subtracting the latter from the first electrical signals in order to determine fourth electrical signals representative of third sound waves produced in the vehicle (2) and heard in the passenger compartment (3).
