 | infrasound //7 hertz infrasound at extremely high decibel levels, can kill "animals & humans alike". fact, infrasound is used by whales...when concentrated by them and used for defensive purposes to subdue prey+enemies. in some rare instances it has been known to even make other animals...to explode "such as squids". *tonal projection note...this is composition of infrasound made to be audible & not what is mentioned above. **infrasound is ultra low frequency or below 20hertz inaudible by the human ear. turn you're bass on. a very powerful tool. "Whales, elephants, hippopotamuses, rhinoceros, giraffes, okapi, and alligators are known to use infrasound to communicate over distances up to hundreds of miles," "Concerning behavioral patterns of animals and the infrasonic effects of natural disasters, animals have been known to perceive the infrasonic waves carried through the earth from such natural disasters and can use these as an early warning. A recent example of this is the 2004 Indian Ocean earthquake and tsunami. Animals were reported to flee the area long before the actual tsunami hit the shores of Asia.[3] It is not known for sure if this is the exact reason, as some have suggested that it was the influence of electromagnetic waves, and not of infrasonic waves, that prompted these animals to flee.[4] Elephants have been known to hear infrasound from two and a half miles away." . credits@ISLA |
 | 15" Subwoofer Test: 6 Hz, 3 Hz and 1 Hz! Some people questioned the ability of hardware to actually play frequencies below 20 Hz (I had an earlier video of a sub doing 12 Hz), so here are a few more examples. It's nothing fancy, simply supplying enough power (volts + current) to a speaker to make it move. In this case, I'm using a computer to generate "sub-bass" frequencies and pumping them through a Yamaha P3200 power amp running at 4 Ohms, 520 Watts to a Cadence 15" car audio-class subwoofer. The volume is turned up and down a few times for each frequency. Note how at 3 Hz and particularly 1 Hz, the dropoff in performance is noted; the sound is still seen, but presumably the efficiency is quite low at this point and a lot of energy is required to make the speaker move. My neighbours would not be impressed, but I suspect these frequencies are too low and low-powered to carry through my walls. It's also worth noting that YouTube videos don't seem to play at 30 fps, so it's hard to see the full detail here. In fact, this video is rather crappy due to that - try viewing the same at vimeo [dot-com]/268968 .. you can also download the original high-res quicktime movie from there. |
 | Bass Pig's Lair - System Subsonic Test Levitates Carpet I was playing the opening 16 hertz organ pedal tone from Also Sprach Zarathustra (Theme to 2001: A Space Oddyssey) and taking some SPL measurements from the far end of the room. When levels reached 133dB @ 16Hz, the carpeting started to float off the floor! The rest of the building was making terrible noises, like joists snapping and other nasty stuff, so I wasn't about to push things any higher, although I had over 10dB of amplifier headroom left. Those Bassmaxx ZR18s never cease to amaze me with the weird things they can do at subsonic frequencies! |

A subliminal message is a signal or message embedded in another object, designed to pass below the normal limits of perception.

InfraSounds are frequency's, (5Hz to about 40Hz), below the normal level of hearing. |
