Apollo Noise - Impact
This page gives a "visual impression" of the "debilitating"
impact that the pulsating Apollo noise has on a "sensitised" listener.
After reading this message a few times one begins to experience the type
of disorientation that is induced by the pulsating Apollo Noise.
Imagine having to have to "live" this type
of interference !!!!

Noise On - Noise Off
PS: We are coming to the
conclusion that it is the random beat note (of some 4 Hz per second) that
arises out of the multiple (circa 33 Hz) pure tones generated by the battery
of large cooling fans that causes us distress rather than the level of
the tones themselves. It is the long term nighttime exposure to this incessant
"throbbing sound" with an irregular beat that has caused us to become "sensitised"
to this debilitating low level VLF noise.
Low frequency pure tones,
just at or above the threshold of hearing, have been found to cause extreme
annoyance. (see:- Broner, 1978b: Tempest 1979: Chatterton, 1979: Leventhall,
1980.)

GRAPHICAL BACKGROUND
The "sine wave" background is irritating. It
simulates the problem faced by Hum Hearers when this irritating sound
invades every facet of their lives: preventing relaxation, interrupting
sleep, interrupting marriages, making simple tasks difficult, even causing
thoughts of suicidal escape (and in one case causing actual suicide: Oct
'96, in the UK.)
