Embodiment Construction

[0014] According to one embodiment, the present invention is based on a method for generating the sound of a specific engine of a motor vehicle. The algorithm of this method is shown in one embodiment. figure 1 in. As a variant, the same method can be used for the sound generation of any rotating machine, or the sound generation of an imaginary machine that does not actually exist. The rotating machine can be any device, such as a helicopter, airplane, train, etc.

[0015] The method first includes the upstream stage of parameter preparation, which will be used to generate synthetic sounds.

[0016] This upstream stage includes the first step E1: Determine the fundamental frequency f of the engine sound 0 (N), and then the n overtones and / or partials i(i 1 To i n ). The engine sound is determined by this fundamental frequency f 0 (N) represents, for all values ​​of the selected overtone and / or partial i, then the frequency i×f 0 (N) represents that the fundamental frequency f 0 (N...

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).

Description

Technical field [0001] The present invention relates to a method for generating sound from a rotating machine, such as the engine of a motor vehicle, train, helicopter, etc., and to a method for generating engine sound in a device such as a motor vehicle. It also relates to a sound generating device that uses such a method to generate engine sound of a motor vehicle. Finally, it also relates to a motor vehicle equipped with such a sounding device. Background technique [0002] Advances made in motor vehicles have made it possible to greatly reduce the noise level inside their passenger compartments. Passengers of vehicles sometimes want to associate a specific sound with the operation of their vehicle, and this reduction in the noise level of the motor vehicle gives them the freedom to apply their choice of sound. [0003] The document FR2924260 proposes a solution for generating synthetic sound inside a motor vehicle, which takes into account the engine speed and the position of...
