Abstract (en)
[origin: WO2020052757A1] The invention relates to a method for operating a device (1) for generating acoustic compensation signals, which are used to compensate acoustic signals (3) that result from the operation of a motor-vehicle drive engine (4), comprising the steps: providing an EOC device (5), which is designed to generate acoustic compensation signals, which are used to compensate acoustic signals (3) that result from the operation of a motor-vehicle drive engine (4); providing a device (6) configured using the EOC device (5) as a model; determining at least one audio signal (10) to be output into a passenger compartment (8) of a motor vehicle (2) by means of an audio output device (7), before said audio signal is captured by an audio capturing element (5a) associated with the EOC device (5); using an evaluation specification to evaluate the at least one audio signal (10) with respect to at least one evaluation criterion; evaluation information describing with respect to the at least one evaluation criterion; controlling the operation of the EOC device (5) in order to generate acoustic compensation signals, which are used to compensate acoustic signals (3) that result from the operation of a motor-vehicle drive engine (4), on the basis of the evaluation information.
