Being a world class insomniac I have purchased a few
of those sleep machines in the past. I used them for a week or two and
they all ended up collecting dust in junk drawers of yore. The problem
was the sounds did not ring true. Maybe it was the quality of the
speakers or maybe they were not diligent in capturing accurately the
sounds that I knew so well.
Example:
Here is a recording of thunder that is pretty much of a standard:
Well that's
all good and fine. But that is not what I hear when listening to a
storm. When I hear distant thunder it rolls... and the same
thunder does not reoccur five minutes later. I have counted
thunder that rolled for over 40 seconds. Its not that unusual. Below is
an example of our take on thunder and background rain. Note the rain
also is binaural.
Relaxing thunder
that is long and rolls; and that does not repeat, is what rings true to
me and I don't think I will find it on any sound machine.

Pure Ambiance
We have just launched a new line of relaxation audio products
called Pure Ambiance. While we
will always cater to the chronic insomniac there are quite a few people
that just want to put our sounds on repeat on their MP3 and bedside CD
players. The new line is more conventional in that respect. There is
less implied movement and certainly less in the way of visualization. In
essence it is sound in it's purest form. We have maintain the spatial
quality and audio innovations that we put into all the sounds but also
realize that people who have less trouble falling asleep might just like
the primary nature sounds that all our products offer.
We will be
adding much more to the Pure Ambiance library in the near future.
Enjoy.

Brainwaves and Sleeping
Our big
human brains run at various frequencies during the day and evening. For
an insomniac such as myself the frequency I strive to curl up with at
night is called Delta. This is the brainwave that represents deep sleep.
The average human's (and aren't we all?) brainwaves
transition from Beta (alert) to Alpha (relaxed) to Theta (daydreams) to
Delta (deep sleep) .
I'm just an insomniac. But having owned a recording
studio I do know a thing or two about audio. Let me correct a falsehood
that has been propagated over the Internet for years. There is no such
thing as an audible Delta sleep tone or sound.
Besides the fact that brainwaves are simply not audible sounds*; the average human can only hear 20 Hz (cycles per second) to 20 KHZ.
Delta brainwaves are represented through EEG's at 0 to 4 Hz . Theta brainwaves; those daydreamy signals
that briefly occur right before you fall asleep, range from 4 HZ to 7 HZ
. Alpha (relaxing) brainwaves occur at 8 to 12 HZ . All are below the
human range of hearing. So, if you happen across any sites that tell you
they have Alpha, Theta or Delta tones to help you fall asleep
fast... walk away.
There is no
such thing.
What we strive for here is the natural induction
of Theta brainwaves. I know from personal experience that it is this
little talked about brain function that is the key to my nightly sleep
quest. When you are in Theta you are not really sleeping nor are you awake. You
can liken it to that far away feeling one might get as they stare out a
window on a rainy day. Theta brainwaves are the bridge to Delta (deep
sleep) brainwaves. The theory behind VirtualDreamer.Com is simple. The
combination of natural soothing sounds that induce calming Alpha
brainwaves with some simple visualization sequences enhances the natural
ability to reach the Theta brainwave state. Ergo, sleep soon follows.
But why?
Simply, when we 'imagine' we use some of the same brain functions
as when we are dreaming. Specifically this area of the brain is known as
the Secondary Visual Cortex
and it is active during REM dreaming. In a sense we prime natural
sleep mechanisms by lulling the big human brain into thinking it's
already sleeping and dreaming.
But what do
I know? I'm just an insomniac.
A really, really bad insomniac.
*Some
research suggests that Tinnitus sufferers are actually hearing the
high frequency sound of their brain's electrical activity that is normally cancelled out by
healthy inner/middle ear functions.
