1. INTRODUCTION OF
BINAURAL BEATS

2. What are BINAURAL BEATS ?
• “Binaural” refers to “relating to” or
“having” or “hearing” with two ears.
• Binaural Beats are generated sound waves
that are created to influence your brain
waves.

3. History
The power of binaural beats was discovered in
1839 by Heinrich Winhelm Dove.
136 years later, Gerald Oster published an article
called “ Auditory beats in brain ”, which was
published in “ Scientific American ” in 1973,it
identified and merge together the scattered
pieces of relevant research done since Dove and
thus provided this subject fresh insight and
relevance to scientific research.

4. How do Binaural Beats
Work?
When signals of two different frequencies
(sounds) are presented, one to each ear, the brain
detects phase differences between these signals.
The brain processes this anomalous information
differently when these phase differences are
heard. A perceptual integration of the two signals
is perceived in the brain, producing the sensation
of a third "beat". The binaural beat is perceived as
a fluctuating rhythm at the frequency of the
difference between the two auditory inputs.

5. The requirements are that the tone is heard
well enough and that it is below about 1000
Hz.
Below 1000Hz, the wavelength of the human
skull is sufficiently small so that the sound
waves curve around it and the binaural beat
appears to come from within.
Researchers discovered that the brain
produce this third low frequency ,this opened
up a whole new world of possibilities and
healing.

7. Gnaural: Binaural Beats
generator
•Gnaural is an open source programmable
auditory binaural-beat generator.
•Gnaural started with a DOS program in the
mid 1990s.
• Progressing to ”WinAural” for Windows,
then ”BrainJav “ for Java.

14. Types of brainwaves
produced by binaural beats
Beta brainwave
Alpha brainwave
Theta brainwave
Delta brainwave
Gamma brainwave

15. BETA BRAINWAVES
(14 Hz to 32 Hz : focused)
•Beta brainwaves are produced when we
are wide awake, alert, active and engaged
in mental activity.

16. Features and Benefits of a Beta
State:
This is the brainwave for the fight-flight
response.
Increased concentration and alertness.
Improved logic, reasoning and critical
thinking.
Feelings of anxiety, stress, scatty unfocused
thought.

17. ALPHA BRAINWAVES
( 7 To 14 Hz : relaxed , yet aware meditative)
These are lower frequency waves.
The state is generated when our thoughts are
really not concentrated and our minds wonder
freely.
Alpha is considered to be the bridge between
the conscious mind and the subconscious
mind.

18. Features and Benefits of an Alpha
State :
Relaxed detached (absent-minded) awareness
and daydreaming mind.
Gateway to meditation.
Increased memory retention , concentration &
focus for super learning.
Alleviates stress and depression.
Reduction of high blood pressure.
Increased motivation, energy, and happiness.

19. THETA BRAINWAVES
(3.5 Hz to 7 Hz : deep relaxation)
Theta brainwave states have been used in
meditation for centuries.
Theta waves are also conducive to
visualization and creativity .

20. Features and benefits of Theta
brainwaves :
Increased sense of inner peace and emotional
stability.
Deep relaxation.
Improved memory.
Increased psychic abilities and sense of spiritual
connection.
Speed healing, improved physical healing.
Sleep onset and better more restful sleep.
Reduce mental fatigue and stress.

21. DELTA BRAINWAVES
(0.1 to 3.5 Hz : deep sleep)
This is the slowest band of waves that our
brains produce and they occur when we are in
deep, dreamless sleep.
These waves are very beneficial for the body
which restores and heals itself when in this
state.

22. Features and benefits of delta
brainwaves :
Human growth hormone (HGH) is anti-aging
hormone that is increased ,due to the stimulation
of the pituitary gland.HGH can also help heal
physical pain.
Increases empathy, understanding, and
compassion for others.

23. GAMMA BRAINWAVES
(40 Hz or higher : Zen mind mastery)
Gamma brainwave states are the most rapid in
frequency.
It is the frequency that brings with it the
ability to process large amounts of
information in relatively small amounts of
time.

24. Benefits of gamma brainwaves :
Have high levels of intelligence.
Being compassionate
Having high amounts of self-control
Having greater than average feelings of natural
happiness.
Increased awareness through your five senses.

25. Where to find binaural
beats?
• Binaural-Beats.com offers a $30 CD that they
call the world's first "digital drug".
• BBM(Binaural Beats Meditation) offers a range
of music tracks.
• Free software is widely available to make your

called Gnaural.

26. Other Advantages of
binaural beats
Relaxation.
Meditation.
Creative Visualization.
‘Chakra’ Tuning.
Extra Sensory Perception (ESP).
Remote Viewing.
Lucid Dreaming

27. Disadvantages of binaural
beats
There are some individuals or groups of
people who should not try these beats :
People who have problems with seizures .
Children .
Pregnant women .
Those who suffer from heart problems or use a
pacemaker .
