Abstract:
The invention relates to a method for synthesizing an engine noise, in particular of an internal combustion engine, wherein the engine noise is generated by at least one electromechanical transducer, in particular an actuator or a loudspeaker, by means of a signal value corresponding to an electrical transducer excitation signal. According to the invention, at least one signal sample (A) having function values (9) is stored in a data memory (3) as a digital data series, such that at signal sample support points (8) following each other in succession at intervals (7), function values (9) are retrievably stored, and such that in accordance with detected and/or pre-definable guide variables as operating parameters of the engine, optionally of a vehicle driven by the engine, function values (9) are retrieved from the data series adapted to the rotational speed and are allocated, level-matched, to signal values in a computing unit (1), and directly or indirectly supplied to the at least one transducer as transducer excitation signals. A device for carrying out the method is also claimed.
