Abstract

Disclosed herein are methods for operating an apparatus for generating acoustic compensation signals used to compensate acoustic signals from operation of a motor-vehicle engine, comprising the steps: providing an EOC device, which is designed to generate acoustic compensation signals used to compensate acoustic signals that result from the operation of the engine; providing a device configured using the EOC device as a model; determining at least one audio signal to be output into a passenger compartment of a motor vehicle by means of an audio output device, before said audio signal is captured by an audio capturing element associated with the EOC device; applying an evaluation specification to evaluate the at least one audio signal with respect to at least one evaluation criterion; generating evaluation information with respect to the at least one evaluation criterion; controlling the operation of the EOC device on the basis of the evaluation Information.

Dependent claims

A method for operating an apparatus (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), characterized by the steps of:

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);
applying an evaluation specification to evaluate the at least one audio signal (10) with respect to at least one evaluation criterion;
generating evaluation information describing the evaluation of the at least one audio signal (10) with respect to the at least one evaluation criterion;
and
controlling the operation of the EOC device (5) 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), on the basis of the evaluation information.
