the high pitched sound which I'm guessing is the whirring sound from the engine's turbocharger/supercharger. the sound comes when the impeller blades of the TC/SC rotates at very high velocity.... it's very similar to the sound of a jet engine but only on a small scale.

sound is wavelengths, and wavelengths get compressed when coming to you (and stretched when going away). the closer the wavelengths, the higher the pitch!

Why is the pitch of a train's whistle higher as the train approaches and loweras it moves away?
This is known as the Doppler effect. As the train approaches you, the wavelength of the sound waves it emits are compressed, and therefore the whistle sounds higher. When the train is moving away, the wavelengths are extended, causing the whistle to sound lower. If the train were not moving at all, the pitch you would hear from the whistle would be somewhere between the high and low pitches you hear when the train is moving.
