The doppler effect:
The doppler effect is where a moving force is admitting a pitch (frequency) of lets say 1000 hz. When that sound is moving toward you, you will generally hear a higher pitch (a higher frequency). As the sound source moves away from you, you should hear a lower pitch. This happens because as sound source is traveling with the sound waves, therefore, macking the sound waves bunched up, and when sound waves are bunched up they admit a higher frequency.
