Abstract

A method and apparatus to balance the brain left side and the brain right side by using binaural beat is disclosed. The disclosed apparatus comprises an electroencephalographic (EEG) system to measure the brain left and right electrical signals, and an audio generator to generate a binaural beat to compensate for the unbalanced EEG frequencies. The disclosed method includes measuring the brain wave frequency spectrum of the individual, selecting the frequency exhibiting imbalanced behavior, and generating a binaural beat of that frequency. The binaural beat can be continuous or intermitten.

Claims

1. A method to balance the brain left and right side of a user using binaural beat, the method comprising

a) measuring a left electromagnetic emission from the left side brain of the user;

b) measuring a right electromagnetic emission from the right side brain of the user;

c) selecting a correcting frequency from the left electromagnetic emission and the left electromagnetic emission, wherein the correcting frequency is a frequency in the vicinity of an imbalanced frequency exhibiting an imbalance behavior;

d) generating a binaural beat of the correcting frequency; and

e) applying the binaural beat to the left and right ears of the user.

2. A method as in claim 1, further comprising a step of generating a left brain frequency spectrum from the left electromagnetic emission, and a right brain frequency spectrum from the right electromagnetic emission.

3. A method as in claim 1 wherein the binaural beat is continuous or intermitten.

4. A method as in claim 1 wherein the binaural beat has different time delay or phase differences.

5. A method as in claim 1, further comprising a step of repeating steps c) to e) while moving the correcting frequency toward the imbalanced frequency.

6. A method as in claim 1 wherein the correcting frequency is higher than the imbalanced frequency.

7. A method as in claim 1 wherein the correcting frequency is lower than the imbalanced frequency.

8. A method as in claim 1 wherein the binaural beat for the corrected frequency is maintained for a predetermined period of time.

9. A method as in claim 1, further comprising a step of repeating steps c) to e) while selecting a balanced frequency that exhibits balanced bahavior, wherein the balanced frequency is a frequency with similar magnitude between the left side emission and the right side emission.

10. A method as in claim 1, further comprising a step of repeating steps c) to e) while selecting another correcting frequency.

11. A method as in claim 1 further comprising a step of generating a rest frequency between two correcting frequencies.

12. A method as in claim 11 wherein a rest frequency is a frequency not in the vicinity of a frequency exhibiting imbalance behavior.

13. A method as in claim 11 further comprising a step of generating a rest period between two correcting frequencies, wherein there is no binaural beat during the rest period.

14. A method as in claim 11 wherein the correcting frequency is the imbalanced frequency.

15. A method as in claim 11 wherein the imbalanced frequency is a frequency with different magnitude or different phase between the left side emission and the right side emission.

16. A method as in claim 11 wherein the binaural beat is generated from two different frequencies to two ears, the two different frequencies ranging from 40 Hz to 400 Hz.

17. A method as in claim 11 wherein the binaural beat is generated from two different frequencies to two ears, the binaural beat frequency ranging from 0.1 Hz to 40 Hz.

18. A method as in claim 11 further comprising the step of repeating the steps a) to e) until a predetermined improved balancing is achieved.

19. A method to balance the brain left and right side of a user using binaural beat, the method comprising measuring a left electrical brain wave spectrum from the left side brain of the user;

measuring a right electrical brain wave spectrum from the right side brain of the user;

selecting a correcting frequency, wherein the correcting frequency is the frequency in the vicinity of a frequency with different magnitude or different phase between the left side spectrum and the right side spectrum;

generating a binaural beat of the correcting frequency; and

applying the binaural beat to the left and right ears of the user.

20. A method to balance the brain left and right side of a user using binaural beat, the method comprising a feedback mechanism using brain measurements from the left side and right side of the user brain to control the binaural beat generation for optimization.
