chest thump, trousers flappin

I had concluded that they occurred at 80 - 100 Hz, until I saw this:

20-40 Hz makes more sense, where sound is as much or more, felt than heard, where music exudes power

That's in real life, the world of reproduction/amplified events has historically shifted it up into these fundamental's harmonics [mid-bass] to keep speaker system size, power requirements at least semi-acceptable as much as practical, though in recent years due to the advent of really high power and speakers able to handle it down low, there's been some willing to pay the price to get a more realistic reproduction of life.

I was at a live gig a few months ago where my trousers were flapping, it was quite fun

The chest resonance of the average male is circa 130Hz.

otto88 · 21st August 2011, 04:15 PM

are you sure it's that high. IIRC though you were in pro sound?

Salas · 21st August 2011, 04:24 PM

Yes as far as I know its there. What we think as bass 20-40Hz is not so in music. That's sub bass. Punch is higher. Most PA brick limit at 40Hz with controllers.

I was beginning think that music is only felt in the "sub bass"

Hi Salas,

According to the link below a chest/thumb occurs at very low frequencies. Btw. - it reminds me of a song with Bobby McFerrin ;-).

Have a look - the chest/thumb frequency range is shown at the lower left corner.

yes, the link says c 20 Hz, while i have heard quoted 80 and 130 Hz . .
octaves apart . .

Salas · 21st August 2011, 04:46 PM

No. Chest is punch. 20Hz its drone like earthquake. Must be wrong. When a heavy truck passes resonating the house, do you feel it in your chest? A kick drum hits there.
