To ensure safe, gentle and effective audio-visual entrainment (AVE),
the DAVID PAL TM offers the following:
- Tru-Vu Omniscreen TM Eyesets - Our unique Tru-Vu Omniscreen TM Eyesets were carefully designed to provide you
with the most effective and safe light and sound experience. The Tru-Vu
Omniscreen TM Eyesets for
the PAL use eight blue-tinted white LEDs mounted over a silver reflector
behind a translucent screen. This disperses the light evenly. Our new
Tru-Vu Omniscreen TM Eyesets
are specially designed to allow for the left and right visual fields of each
eye to be individually stimulated rather than the entire eye. With the Tru-Vu
Omniscreen TM Eyesets, the
lights flash into the left visual fields of both eyes, then alternately
flashes into the right visual fields of both eyes. This approach allows the
ability to stimulate either visual cortex with a frequency different from the
other visual cortex. For example, a person who functions strongly from the
left brain could have 8 Hz stimulated into the right visual field (and
therefore the left brain) to slow down left brain function and have 18 Hz
stimulated into the left visual field to increase right brain function.
- Isochronic Pulsed Tones, Binaural Beats and Chime - The
tones of the DAVID PAL TM are evenly spaced, are of equal pitch and are turned on and off
at a specified rate. This is important to enhance the effectiveness of audio
entrainment.
- Soft-Off TM - The gradual lowering of the lights
and tones at the end of the session prevents a startle response (also known as
somnatic shock). Soft-Off TM ensures that relaxation and other benefits carry over even after a session has
ended.
- Battery Power Indicator - At a quick glance you can tell if your
battery has enough power to run your session. New eyeset technology
allows for much longer life for your 9-volt battery.
- Easy-To-Find Intensity and Volume Buttons
- The intensity and volume buttons are raised so that you can make the
necessary adjustments easily and quickly, even with your eyes closed. Adjust
the intensity of the Omniscreen TM Eyeset with the easy-to-find INT
button.
- 30 Preset
Sessions - Including Brain Brightener (for ADD and cognition),
Fractioned Hypnosis, Alpha/Beta Mix (for depression), Schumann with
Dissociation & HRV (for meditation), Beta Perker, Theta with Dissociation
(for sleeping), and Sound Sync (to turn your music into an intriguing light
show).
HEART RATE VARIABILITY (HRV):
For the first time ever, a system exists where meditative breathing
may be paced along with an audio-visual entrainment (AVE) session. Long,
graceful breathing cycles have been used as part of meditation. Scientifically,
this technique has been analyzed and shown to settle down a stressed autonomic
nervous system. Both sympathetic (flight-or-fight) activity and para-sympathetic
(the brain’s efforts to compensate) activity settle down dramatically using HRV
techniques.
The heart speeds up with every breath in and slows down with every breath
out. This swing in heart rate is HRV. A typical heart beat swing is in the order
of about 15 beats per minute (bpm). When people get stressed, the heart
typically clamps to sometimes as low as five bpm HRV at times intermixed with
sharp spikes in heart rate. This is all abnormal activity and is rough on the
heart.
The HRV technique used clinically is based on a 10 second breathing cycle
(six breaths/minute, by inhaling slowly for five seconds and exhaling slowly for
five seconds in an easy, relaxed breath). When using HRV paced breathing, listen
to the heartbeat generated by the DAVID PAL TM through the headphones. Inhale for two
heartbeats and exhale for two heartbeats (not your own heartbeats!). Most
sessions begin at seven breathing cycles/minute (28 heartbeats/min) and slow to
six breaths /minute (24 heartbeats/min). This allows the user to breathe a
little faster at the onset of a session until he/she has had time to relax.
