Very Low Frequency Noise:
--Many modern sounds have very low frequency (VLF) components, for example...amplified bass music.
sounds of a higher pitch, one cannot habituate to them….
cause extreme discomfort even when only just audible….
capable of causing a range of symptoms which are known to include: loss of
concentration, a sensation of pressure inside the ears, pain at the base of the
skull, nausea, and hallucinations….after prolonged exposure plus failure to get
the authorities to do anything about it, people may suffer psychological
damage, and several suicides have been reported in the press.
is happening? The
answer is ‘forced vibrations’. A person inside that building is surrounded by
six surfaces (four walls, ceiling and floor) all vibrating at close quarters
within a closed environment, and all six surfaces are producing sound waves.
--This is a widespread problem which
is not even officially recognised, let alone addressed. The result is many
highly distressed individuals who live inside homes which have been turned into
hell. They are unable to sell and move away, because who will buy the property?
--…Leading scientists have been
condemning the use of A-weighting for VLF’s for at least two decades, and the
World Health Organisation has published a document which makes the same point.
--Conclusions: The system in which
are vested the authority and the power to deal with this kind of problem, is
riddled with ignorance at every level from junior local Officers right up to
Government itself. Much of this ignorance has become institutionalised in the
form of pseudo-science and pseudo-law.

How loud is low frequency noise.
comes to assessing noise, the conventional wisdom is that the loudness of a
sound will correlate well with its perceived annoyance. On this basis, the
A-weighted sound pressure level is also assumed to correlate with the potential
perceived annoyance of a sound. This might well be a reasonable assumption for
mid range frequency sounds. But for low frequency sounds… the assumption that
loudness is correlated highly with perceived annoyance breaks down.”

Neighborhood Noise: Serious Health Endangerment
noises are sounds with high information content such as language, music or also
the noise of footsteps. It is in the nature of humans to have their attention
drawn to such informative sounds, even if the sound level is relatively low.
The annoyance potential of neighbourhood noise is therefore relatively high
also at low noise levels and is heightened by the hearer's knowledge of the
sound producer and other things causing the noise.
the public and many experts still underestimate the health impacts of noise in
the residential environment. Noise can affect the neurological system directly
or indirectly.... In this way, metabolic procedures, the
regulation of vital body functions and the immune system can be influenced.

The health effects of permanent noise stress can reveal themselves ten to fifteen years later in different functional systems. See more.Niemann H, Bonnefoy X, Braubach M, Hecht K, Maschke C, Rodrigues C,

It's believed one in 10 move due to a noise problem. "We want to try

such extreme measures. When problems drag on for a while, we see the deterioration in people and that it's making them ill."

“…Noise can be one component of intimidation used.”
Amplified music is often the main problem. One environmental health inspector explained:
are so many noise-making pieces of hardware in houses, with
Playstations, play CDs, TV, of course you’ve got the big TVs with
surround sound systems. The obvious ones like radios and amplifiers,
but you’ve also got these people who have in a small domestic flat the
sort of sound systems you’d associate with a club. Great big amplifiers
with loudspeakers as big as an armchair. And they would say they were
DJs practicing their trade, developing their trade at home.”

World Health Organization and Low Frequency Noise
"Special attention should also
be given to ... noise sources with low frequency components."
"Stronger reactions have been
observed when noise is accompanied by vibration and contains low frequency
"If the noise includes a large
proportion of low frequency components still lower values than the guideline
values ... will be needed."
"When prominent low frequency
tones are present, noise measures based on A- weighting are
"Disturbances may occur even
though the sound pressure level during exposure is below 30dBA."
"It should be noted that a
large proportion of low frequency components may increase considerably the adverse
effects on health."
"The evidence on low frequency
noise is sufficiently strong to warrant immediate concern."
"Health effects due to low-frequency
components in noise are estimated to be more severe than for community noises
in general (Berglund et al. 1996)."

"At low frequencies, loudness
changes more rapidly with changes in level."
noise. . . is brief and abrupt, and its startling effect causes greater
annoyance than would be expected from a simple measurement of sound pressure
noise is not equally annoying
Not all noise has the same
effect on humans, nor do all humans react in the same way to noise
stimuli. Certain noise characteristics can greatly increase the annoyance
factor and the potential health impacts associated with noise. In
addition to the sound pressure level, these factors include: 1)
difference between the new noise and the prior ambient noise environment; 2)
the presence tonal noise; 3) low frequency noise;
4) fluctuating, intermittent or periodic sounds;
and 5) impulsive sounds.
Care should be exercised to
distinguish between sound pressure level, sound power level, sound
intensity level, and sound or noise level.
Noise does not have to be loud to be harmful
Noise does not have to be loud to be harmful. A dripping faucet, a
neighbour's blaring television set, an overhead jet - all may cause stress to
the body's system. If sustained over time, this stress may lead to physical
ailments. (Kryter, 1985; 1994; Fay, 1991; PasschierVermeer, 1993; Tempest,

The Psychological profile of a sound
From our studies, people that use noise in situations that are not qualified as
an emergency, expose these forms of behavior:
1. Lack of awareness
2. Lack of responsibility
5. Lack of respect for others
6. Lack of respect for one self
7. Defiance, abusive behavior
