Method and apparatus for changing brain wave frequency

An apparatus for urging the brain wave frequency of a user toward a desired brain wave frequency, the apparatus comprising in combination:

• means for determining a current brain wave frequency of the user;
• means for generating a first signal at a first frequency;
• means for generating a second signal at a second frequency wherein [the] there is a frequency difference between the first frequency and the second [signals] frequency and the frequency difference is between the current brain wave frequency and the desired brain wave frequency and is within a predetermined range of the current brain wave frequency;
• and
• means for producing an output detectable by the user corresponding to the first and second signals to generate a beat signal [equal to] at the frequency difference.

An apparatus for urging the brain wave frequency of a user toward a desired brain wave frequency, the apparatus comprising in combination:

• a computer processor;
• [a memory which can be written to and read from the computer processor;.] .
• means in communication with the computer processor for determining a current brain wave frequency of the user[, which communicates with the computer processor];
• a programmable timing generator operatively connected to and responsive to the computer processor [and] for generating a first signal at a first frequency and a second signal at a second frequency wherein [the] there is a frequency difference between the first frequency and the second [signals] frequency and the frequency difference is between the current brain wave frequency and the desired brain wave frequency and is within a predetermined range of the current brain wave frequency;
• and means responsive to the programmable timing generator and detectable by the user for producing an output corresponding to the first and second signals.

A method for stimulating a user, comprising in combination the steps of:

• determining a desired brain wave frequency;
• determining a current brain wave frequency of the user;
• generating a signal at a frequency between the current brain wave frequency and the desired brain wave frequency which is within a predetermined range of the current brain wave frequency;
• and
• producing an output detectable by the user at the signal frequency.
