Something churches know; which is why those massive pedal-note pipe

Interestingly enough, that is NOT true for all people. When I was
at school, I found that there was no gap between the sounds that I
could feel and those that I could hear. But I did cut off at 12,000
cycles. I now realise that part of that is because my hearing is NOT
more sensitive than my touch, which it is for most people.
