A system for reproducing synthetic engine sound in at least one listening position of a listening room is described. In accordance with an example of the invention, the system comprises a model parameter database including various pre-defined sets of model parameters. An engine sound synthesizer receives at least one guide signal and is configured to select one set of model parameters in accordance with the guide signal(s). The engine sound synthesizer generates a synthetic engine sound signal in accordance with the selected set of model parameters. At least one loudspeaker is used for reproducing the synthetic engine sound by generating a corresponding acoustic signal. Moreover, the system comprises one of the following: (1) an equalizer that receives the synthetic engine sound signal and that is configured to filter the synthetic engine sound signal in accordance with a filter transfer function, which is set such that the effect of the listening room on the resulting acoustic engine sound signal is approximately compensated at the listening position(s); and (2) a model parameter tuning unit, which is configured to modify the pre-defined sets of model parameters in the model parameter database in accordance with an equalizer filter parameter set such that, when the resulting synthetic engine sound signal is generated from a modified set of model parameters, the effect of the listening room on the resulting acoustic signal is approximately compensated at the listening position(s). |
