A system for inspecting an acoustic treatment applied to the hull of a maritime vessel includes an underwater inspection system including at least one signal emitter configured to emit a signal, at least one receiver configured to receive the signal after the signal has come into contact with the acoustic treatment applied to the hull of the maritime vessel, wherein the signal provides information about the integrity of the acoustic treatment and a processor configured to perform signal processing on the received signal and generate an output comprising information about one or more parameters of the acoustic treatment. The inspection system thereby allows for in-water inspection of acoustic treatments applied to a maritime vessel thus avoiding the need for a costly and time-consuming inspection of such a vessel while in dry-dock.

The invention relates to a method for operating at least one ultrasonic sensor (4, 6) of a driver assistance system (2) in a motor vehicle (1), wherein an output sound signal (S.sub.A) of the ultrasonic sensor (4, 6) is modulated in accordance with a type of modulation and by means of this modulation, a specific codeword is impressed on the output sound signal (S.sub.A). For at least two mutually different functionalities (8 to 12) of the driver assistance system (2), different types of modulation are in each case used for the modulation of the output sound signal (S.sub.A) and/or in each case different lengths of the codeword.
