Introduction to binaural beats
- 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 own binaural beat by an open-source program 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 .
