ELI5: seriously, why in movies are the voices so quiet and the sound effects so loud?

and what's the deal with ads being so loud?

most movies are meant to be played on a 5.1 or 7.1 surround system with a center channel speaker reserved for voice. Most of the voice is channled through that speaker. So if you listen to it with a set of 2 speakers or somtimes headpones the balance is off because all the voice is not seperated.
