Abstract
The invention relates to a method for generating sound for a rotating machine, including a step (E1) of determining the frequencies and amplitudes of n partials and/or harmonics (i) pertaining to the sound of a rotating machine, characterized in that the method includes a step (E2) of determining values (a1) and a step (E7-E8) of calculating a synthetic sound for the rotating machine, said synthetic sound being composed from the n partials and/or harmonics (i), while the frequency thereof is entirely or partially shifted by the values (ai).
