The Hemi-Sync® series of audio CDs can help children, teens and adults
of all ages sleep, relax, concentrate, and energize. My family
has been using these CDs for over 5 years, and after receiving
many requests for advice on how help a child get to sleep and/or
return to sleep and improve a child's ability to focus and concentrate,
I have decided to offer these CDs. The
Hemi-Sync CDs help by creating regular brainwave pattern within the desired mental
state when listened to through stereo headphones or through the speakers
of a stereo system. The CDs we offer are
non-verbal and can be used for young children.
How Hemi-Sync CDs Work
Theta Brainwaves Without Hemi-Sync
Theta Brainwaves With Hemi-Sync
Hemi-Sync causes the brain to
generate desired brainwaves by using multi-layered patterns of sound frequencies.
When a Hemi-Sync CD is listened to through stereo headphones or
A sound played in the
left ear is heard as a single tone.
A sound played in the
right ear is also heard as a single tone.
When played together
the brain combines the two separate tones as a vibration called the
When the brain automatically adjusts the two separate tones
to create a binaural beat, this causes the brain to create the desired brainwave patterns and
creates more regular brainwaves within the desired mental state.
Regular brainwave patterns
promote optimal mental states for learning, sleep, relaxation and
physical activity. Children within the autism spectrum and
with ADD/ADHD tend to be more disorganized neurologically and have less
regular brainwave patterns which can interfere with sleep, learning and
other mental processes. The results of Hemi-Sync regulating
brainwave patterns may be similar to the results provided by
There are different CDs
available to help promote mental states of Sleep (Delta brainwaves),
Relaxation (Theta brainwaves), Concentration (Alpha brainwaves) and
Energy (Beta brainwaves). The following CDs promote these different brain
When a member of our
family, including our son, has difficulty sleeping, we use Sleeping through the Rain.
Typically, within 20 minutes of turning on this CD with headphones on
a portable CD player, we are out cold! This CD begins with the soft noises of a thunderstorm in the
background and includes soft dreamy music. We have even loaned
this CD to ADD/ADHD teenagers in
our neighborhood who were having difficulty sleeping and they have also
reported this CD was very helpful putting them to sleep.
There is another
sleep CD, Super
Sleep, which has a "pink" background noise that has a
faint swishing sound that reminds some people of the ocean - no music - and is effective even when played at a
the ocean sound is barely audible.
According to Hemi-Sync,
children in the autism spectrum respond well to the Surf CD,
which contains sounds of the ocean. There have been reports of greater calmness
and improved eye contact with autistic children in classrooms using
this CD. If you or your
child likes classical music, we recommend Masterworks, which
contains beautiful music of classical Baroque composers, including Vivaldi.
They are nice to put on at the dinner hour as well, to help everyone
unwind after a busy day.
Focus and Concentration
These CDs really seem to
help our son concentrate on his homework and get it done in a more
timely fashion. We especially like Einstein's Dream
which plays Albert Einstein's favorite music composition - an
exquisite classical Mozart concerto for two pianos. If you prefer
more contemporary sounding music, we recommend Remembrance,
which has a New Age style composition and is liked and has been effective with children within autism
spectrum and with ADD/ADHD. These CDs would also be good to
play in a classroom during times of study and test taking.
Energy and Physical Activity
We listen to
the Ecstatic CD to increase energy and improve athletic
performance. It is a lively tribal-sounding composition consisting
entirely of percussion instruments.
If you wish to substitute
one title for another in a set, please place your order for the set and
