Ok, without making my head explode, what is the difference between volume and pitch?
Because no matter my motion, standing still, or being in motion myself, I do know somthing off in the distance I am not going to percieve as being as loud as something right next to me. And as well, after it passes me and moves off in the distance it I will not percieve it as loud as if both of us were stationary right next to each other.
Yes, all if that is true, but none of it describes the Doppler effect.
The Doppler effect describes how the wavelength of a sound (or light) emitted by a source is stretched or compressed as it either recedes from or approaches toward you. Lower wavelength sound = lower pitch. Thing about a guitar's strings. The larger strings create sounds lower in pitch because they vibrate at a lower frequency.
