This audio CD is meant to improve focus by removing, or
masking, distractions from surrounding ambient noise. It has
been used to prevent insomnia, reduce pain, increase
awareness, and in many other natural health applications.
White Noise is 100% random audio data covering the entire audible spectrum.
It sounds like the hiss of the wind, or the crash of ocean waves, but very
consistent and repetitive. Technically, it's sound that contains all the
human audible frequencies ( 20 to 20khz ) at equal power across the audible
The U.S. Government suggests White Noise for Tinnitus sufferers. The
National Institute on Deafness and Other Communications Disorders ( NIDCD
) recommends mild noise to 'mask' sounds and which helps Tinnitus sufferers
sleep and perform other tasks.
White Noise is widely used in office environments to reduce the cross talk,
or interference, caused from conversations in adjacent cubicles. This effect
is called masking, which is the same effect which promotes healthful sleep
by reducing external noise in our bedroom at night.
White Noise is conducive to relaxation, as white noise inherently sounds
like nature, the wind, the sea, etc. It is often used as a sleep aid. In
fact, large chains like The Sharper Image and Radio Shack sell electronic
'white noise' simulators for business travelers for much more money, with
less quality sound. The white noise on this cd is true stereo random and
is recorded at 0dbfs - that's the maximum volume you can record at without
You've often seen 'sounds of the ocean' recordings for sale - white noise
is much less attention drawing, hence, it's more capable of allowing you
to focus and relax without bringing your attention to it.
Audio enthusiasts can use this to balance speakers and adjust equalizers.
On the more cynical side, many people also use white noise as a deterrent
to electronic surveillance. Apparently, white noise can render many bugs
useless by masking subtle conversation with itself to make extraction of
the voice segment of an audio recording very difficult, if not impossible.
Question: Is White Noise the same as radio static?
Answer: No - radio static is just that - random static. It does not
cover the entire audio spectrum nor is it consistent enough to be used
practically for measurements. White Noise is random equally over the 20 -
20khz spectrum and has a 'smooth' color, as opposed to the cracking and popping
associated with radio noise.
Question: Is White Noise the same as Pink Noise?
Answer: No - White Noise has it's energy equally distributed across
the entire audio spectrum while Pink Noise is typically -3db per octave.
It's easy to make Pink Noise from White Noise with an Equalizer. Even a simple
tone control can simulate Pink Noise quite well. On the other hand, it's
difficult to make White Noise from Pink Noise.
Question: Is White Noise used in industrial sound masking?
Answer: Yes and No. Many systems start with White Noise and then adjust
the EQ to match the room. Other systems pre-calculate the proper EQ and provide
a pre-eq'd wave. In either case, it all starts white.
Question: What's all this about Tinnitus?
Answer: Millions of people have Tinnitus (tin-NY-tus) -
a condition in which sufferers have a ringing, roaring, clicking, or hissing
sound in their ears all the time. It is associated with hearing loss. Many
people who have Tinnitus have reported headaches when listening to certain
sounds. White Noise has proven effective in providing some relief by providing
a 'masking' effect over the ringing sounds they hear.
To use this cdrom, play track 1 in a boombox, stereo system, or even portable
cd player. Adjust the volume just loud enough to mask out external sounds.
After a short period of time, you'll stop noticing the white noise itself,
and all will seem quiet. You can loop,or repeat, the cd for an endless supply
of white noise.
