You got two ears. Usually the sound comes as pressure waves from outside the head, goes through the ear canal and hit one ear drum at an earlier time than the other and with a louder level than the other.

How the sound at the moving ear drum is converted to nerve pulses to reach your brain is very complicated and yet not full understood.
