Infrasound and the other one, not sure of the correct name?


I’m FASCINATED by infrasound, I believe infrasound are sound frequencies BELOW 20 Hz.? But what are sound frequencies above 20 KHz. called? The frequencies below 20 Hz. can affect you physically. Are made/used by big cats (tigers, lions, I believe gorillas as well) to literally stun their prey, by producing these frequencies. That is SO fascinating to me!! And wondering if there is anything to music frequencies ABOVE 20 KHz being of any value?? Can the human body be affected by them? Sense them? There are tweeters that go close to, and maybe above 100 KHz. Is there anything to: sounds or music frequencies above 20 KHz??? Would LOVE to learn more about this topic!!!

there is a device which claims to improve sonics by injecting a combination RF and infrasound into the listening environment, It is possible that standing waves could be created in large rooms, and that these could possibly affect the rendition of sound at the listening position. Another possibility is that the frequencies could affect the physiology of the listener in some manner.

It is difficult to fathom how the injection of RF could be of any benefit, and it is probably a chimera added for marketing purposes.

Thank you! Duh. My brain isn’t as sharp as it used to be! Thank you God, my hearing is still good! Went for a hearing test, they were surprised a 52 y.o., could hear up to 14Khz. That’s pretty good! Ultrasonic. That’s it! But the infrasound, below 20 Hz. frequencies, is SO fascinating! Was watching a documentary on big cats, mostly Tigers, and how they use infrasound to stun their prey. VERY cool! Would LOVE for a sound engineer to comment on this! Learn more about it and ultrasound as well!! This topic REALLY fascinates me!

 how they use infrasound to stun their prey

may also apply in case outlined above

Orca/whales ultra sound they mastered water

Elephants Subsonic/ultrasonic they got the pipes

Bats, sonar

Don't get me goin' on snails. :-)

Nature is full of STUFF..

Snails?? Yes, wales and dolphins! Forgot about them! 
 Would still love to hear from a sound engineer about all of this! So fascinating!

Infrasound affect the body/mind so greatly that it can induce depression and ghost sensation presence...

It can even induce hearing loss...

See wikipedia infrasound....

Funny you say sound engineer. I worked with a lot of Engineers. I met a couple of sound engineers on a Los Vegas job sight. They knew very little about speakers manufactures. They sure knew how to move sound around in that town. People could sleep in one part of a hotel, Lady Gaga blaring in another part and nobody outside hears any of it..

Not to mention the whole town sets in a dried lake bed of natures concrete (Caliche). I had to keep generators going a couple of time behind shows demanding good clean Cat power. Electronic shows were real picky. They were very quiet but they could tear you up working inside the van. Outside quiet as a mouse, LESS the 6-12hz bump. It will actually bust up the concrete pads.. 

I've seen them loose isolation on either end of a balanced main shaft and self destruct.

Destructive harmonics can be very damaging to YOU, be very careful. Serious! be careful.. I've worked dam face generators that you were limited to the time where the turbans are anchored. Puffs suits at a minimum. Your bones will crumble.

I use to have a chamber here that would hit 10hz and 135+db no sweat. I've left more than one person with a nosebleed and not able to breath. KIDS.. 

I like subs, I don't like sub frequencies from them everywhere in my house though.
