Combustion gas of an internal combustion engine passes through an exhaust system to an outlet opening. A detection device generates a state signal that describes an engine noise of the internal combustion engine. A control apparatus actuates at least one loudspeaker to produce a sound at the outlet opening based on the state signal to compensate for the engine noise or produce another engine noise, independently of the state signal based on predetermined audio data and thereby to use the at least one loudspeaker to audibly output an advisory signal described by the audio data.
