The human hearing has a frequency range of 20hz - 20khz. Young children
have a much greater range. Humans cannot hear lower frequencies,
sub-woofers only allow you to feel lower frequencies.
In fact, it is possible that I made a mistake above. I think it is a
limit of 50hz as the lowest frequency limit.
As an example the human liver resonates at around 2-3 hz or is it
2-3khz.
Cheers,
Mike
