A Study of the Effects of Low Frequency Sound and Infrasound

Low frequency sound (LFS) and particularly infrasound have intrinsically mysterious effects as they generally bypass the ear mechanism and are predominantly felt and not heard. This coupling of sound directly to the body may be responsible for feelings of anxiety due to a lack of cognitive resolution within the individual.

Notes:
General Sound Information
a) Sound perceptible to humans 20Hz - 20kHz
b) Pain begins about 120dB, eardrum ruptures at 160dB
c) Frequencies above 20kHz = ultrasound, below 20Hz = infrasound (LFS)

Qualities of LFS
a) Inaudible
b) Undetectable on most barometric equipment
c) Invisible (of course, it is sound)
d) No solid barrier known to change the frequency
e) Can be disrupted by opposing sound waves
f) Travels along the ground - Low frequencies "hug the ground"
g) Long wavelength
h) Low material absorption
i) Travels vast distances
j) Almost impossible to pinpoint origin of LFS

LFS Effects on Humans
a) Nausea
b) Disorientation
c) Fear
d) Deep Sorrow
e) Nervous Feelings
f) Revultion
g) Gagging
h) Strong heat in areas with pocket air (mouth, ear, between fingers)(165dB)
i) *Range of Death* 3-7 cycles/second

LFS *Range of Death* Effects
a) Extreme physical pressure
b) Pain in ears and eyes
c) Simply- you get vibrated apart

LFS Human Tolerances
a) Non-lethal 40 - 100 cycles/sec

b) 100 cycles/sec Effects
i) mild nausea
ii) giddiness
iii) skin flush and tingle

c) 60 - 73 cycles/sec Effects
i) coughing/choking
ii) inability to breathe and sternal pain
iii) abdominal pain

d) 43 - 73 cycles/sec Effects
i) intelligence falls to 77% of normal ability

Questions Posed?
1) Research Tesla's LFS Energy Board
2) Research Test for Fear Frequency
3) Is there a LFS generator available?
4) Is there a LFS detection machine available?
5) Could Theatre Acoustics change the sound outcome?
6) Is there a frequency that raises blood pressure but does not cause nausea?
7) Is LFS legal to experiment with?
8) Definitely become more educated about LFS before experimentation.
