First Claim
Patent Images
1. Apparatus for varying the brain state of a person, comprising:
- means for producing a first audio signal to be supplied to one ear of the person;
means for producing a second audio signal to be supplied to the other ear of the person;
means for substantially continuously varying the frequency of both of said first and second audio signals only in a first direction in a range of approximately 0-60 Hz and in a substantially identical manner, so as to vary the brain state of the person; and
amplitude varying means for relatively varying the amplitude between said first and second audio signals such that said first and second audio signals are provided with different amplitudes substantially at all times so that the person perceives a moving sound.
