The dopler effect is what makes objects far away seem smaller or sound weaker.

 

Can anyone explain the science behind it?

Well, it changes the pitch. And is related to speed, rather than distance.

 

Wikipedia has a simple explanation: https://simple.wikipedia.org/wiki/Doppler_effect

Doppler effect depends on velocity vector (not speed, like Strange said, which is scalar).

 

If somebody is flying toward sound/light source,

he/she will find out frequency is increased,

but while flying in opposite direction,

he/she will find out frequency is decreased..
