The acoustic characteristics of the Mercedes Formula 1 engine can be likened to those of a locomotive, albeit with a modified pitch. The perceived auditory frequency of the engine in the simulation appears to be slightly lower than the actual engine noise, with the sound at 12,000 RPM in the game corresponding to the real-life sound at approximately 11,000 RPM. Additionally, the engine emits a whine that is harmonically 1.5 times higher in frequency than the primary engine sound. Despite the presence of a turbocharger, its acoustic signature remains relatively subdued. How would YOU describe this engine sound?
