don't forget there are under and overtone harmonics that effect the actual frequencies our hearing allows.
Also the volume of sound affects the way we percieve it. If there is enough bass in a sound that it vibrates you , your clothes, the walls etc... You "feel" the sound as well as hear it. We don't only hear sound sometimes we can "feel" it too.
But very generally, the accepted frequency range the human ear can hear is 20 Hz to 20,000 Hz.
