I'm not really interested in the frequencies we can hear, i'm interested in the one's we can't. So, my original question is important.

We can't seem to record frequencies below 20hz and above 20khz, but, that doesnt mean they don't give an effect to what we hear.
Consider a concert hall with a symphony; the violins are rich in the high end and have an abundance of frequencies above 20khz. We can't hear those frequencies above 20khz, however its presence makes a difference in the audible sound spectrum, that's why its almost impossible to replicate the effect of a live symphony onto concrete music (cds, vinyl, hd, etc)
The same applies to the metro train getting closer to a station vs its low end below 20hz.
