Default chest thump, trousers flappin

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

Interactive Frequency Chart - Independent Recording Network

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.

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

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

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.

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.

Karsten :-)

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.
