[QUOTE="awalbert88, post: 155177, member: 545461"] Wow, that article is quite an interesting read! I wonder if the story about the ‘Feraliminal Lycanthropizer’ is true. Now I sure wouldn't mind trying that out! [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] So THAT's why some people can feel storms coming. Never thought about it, but infrasound can be felt at much longer range than ultrasound, so that makes sense. Just like the Elephants hearing 0.1hz and being scared away from the storms. Or many other animals instinctively hiding before storms. Very interesting stuff. I wonder if this also explains why some people find it so easy to fall asleep with a muted TV on (creating that high-pitched hum)? There's no doubt that various sound frequencies have strange effects on humans and animals, and I don't doubt that a sufficiently powerful infrasound blast could kill an animal (for example, 170db at 5hz). But killing a human is another question. What frequency does the heart resonate at? And would that frequency carry through flesh, bone, and muscle to reach the heart with enough strength to damage it? I don't question that waves can carry tremendous energy, but this is a debate pertaining to sound waves in particular, and especially the sub-20hz range. This is all quite interesting, nonetheless. Oh, and Lloyd - you're crazy! I hope you didn't [I]intentionally[/I] expose yourself to those db levels! [/QUOTE]
