Abstract
Abstract Frequency reduction in human brain wave is inducible by allowing human brain to perceive 4-16 hertz beat sound. Such beat sound can be easily produced with an apparatus, comprising at least one sound source generating a set of low-frequency signals different each other in frequency by 4-16 hertz. Electroencephalographic study revealed that the beat sound is effective to reduce beta-rhythm into alpha-rhythm, as well as to retain alpha-rhythm.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
89 words
An apparatus for inducing frequency reduction of human brain wave, comprising: (a) means for generating a first low-frequency signal which is higher in frequency than the range of 4 to 16 hertz; (b) means for generating a second low-frequency signal which is higher in frequency than the range of 4 to 16 hertz and is different in frequency by 4 to 16 hertz from the first signal; (c) means for sounding the first- and second signals to generate a beat signal of the frequency of 4 to 16 hertz.
Claim 2
Independent Claim
89 words
An apparatus for inducing frequency reduction of human brain wave, comprising: (a) means for generating a first low-frequency signal which is higher in frequency than the range of 4 to 16 hertz; (b) means for generating a second low-frequency signal which is higher in frequency than the range of 4 to 16 hertz and is different in frequency by 4 to 16 hertz from the first signal; (c) means for sounding the first- and second signals to generate a beat signal of the frequency of 4 to 16 hertz.
Claim 3
Dependent Claim
19 words
The apparatus in accordance with claim 1, wherein the frequency of the first signal is 120 to 180 hertz.
Claim 4
Dependent Claim
33 words
The apparatus in accordance with claim 1, wherein either or both of said generating means comprises a means for generating a low-frequency signal and a means for lowering the frequency of the signal.
Claim 5
Dependent Claim
21 words
The apparatus in accordance with claim 3, wherein said frequency lowering means is coupled with the sounding means through a waveform-modifier.
Claim 6
Dependent Claim
16 words
The apparatus in accordance with claim 3, wherein said frequency lowering means is a decade counter.
Claim 7
Dependent Claim
18 words
The apparatus in accordance with claim 1, wherein said sounding means is at least one earphone or loudspeaker.
Claim 8
Dependent Claim

Claim 9
Independent Claim
114 words
An apparatus for inducing frequency reduction of brain waves of human subject, comprising: (a) first means for generating a first low-frequency signal which is higher in frequency than the range of 4 to 16 hertz; (b) second means for generating a second low-frequency signal which is higher in frequency than the range of 4 to 16 hertz and is different by 4 to 16 hertz from said first low-frequency signal; and (c) means for sounding said first- and second-low frequency signals to generate a beat signal of the frequency of 4 to 16 hertz; whereby upon perceiving said beat signal by the human brain the ongoing state of brain wave is shifted to alpha-rhythm.
Claim 10
Independent Claim
114 words
An apparatus for inducing frequency reduction of brain waves of human subject, comprising: (a) first means for generating a first low-frequency signal which is higher in frequency than the range of 4 to 16 hertz; (b) second means for generating a second low-frequency signal which is higher in frequency than the range of 4 to 16 hertz and is different by 4 to 16 hertz from said first low-frequency signal; and (c) means for sounding said first- and second-low frequency signals to generate a beat signal of the frequency of 4 to 16 hertz; whereby upon perceiving said beat signal by the human brain the ongoing state of brain wave is shifted to alpha-rhythm.
