How low can one hear Huh?? Say again

I read a review and the reviewer wrote "one can not hear sound below 30 htz" (??)
Of course he was referring to music.
I am not audiologist, but I think this is total B.S.
If that were so,we could all be happy with speakers that just go down to 30htz.
I've had speakers rated at 30htz, 26htz and presently own speakers rated at 20htz.
HUGE difference between the 30htz and 20htz speakers and a very noticeable difference between the 26htz and 20htz speakers.
Where is this reviewer coming from???

The reason subs work well is because at around 60hz your ear can no longer pick-up it's location with ease. At around 25hz in my room you can hardly hear the sub even though it still measures 80 db on the spl meter...you can feel the room begin to flex. At 20hz. and 70db output as measured with the spl meter you can not hear the bass at all...you can feel the room, cement floor and everything in the room begin to shudder at this very low freq.

A good test with sustained low bass freq is Archetribe (earthtones) which is " world " or newage type of music. Play it and feel your room, even if you can't hear it.

" Any other ideas?"

Headphones and in-room are not the same so kind-of apples and oranges. The ear does not respond in the same way to each and is the only reason why tiny headphones can do deep bass.

elephants also hear (feel) through their feet from many miles away. I was watching a show the other night regarding this and at one point all the elephants in the herd would raise one front foot off the ground at the same time in response to far away sound? Falling to sleep at about this time I did not get a clear enough picture of this to fully understand.

Sorry to go off topic but your post made me remember this.
