Sound generating apparatus and method, sound generating space and sound, each provided for significantly increasing cerebral blood flows of persons

A method for generating a sound, comprising:

• switching on a first switch and a second switch, said first switch for cutting off sound in a first frequency range and said second switch for cutting off sound in a second frequency range different from the first frequency range;
• generating a sound in said first frequency range that ranges from above a predetermined audible frequency range to a predetermined maximum frequency, wherein said generated sound is in a non-stationary state so as to change in a micro-temporal area in a frequency range above 10 kHz;
• and
• applying said sound to a person, thereby increasing cerebral blood flow of the person as indicated by increased α-EEG activity of the person's brain, wherein said second switch cuts off the second frequency range from being applied to the person and wherein the non-stationary state characteristic of the generated sound is required for generating a hyper sonic effect to increase α-EEG activity of the person's brain in an effort to reduce human stress.

A sound generating apparatus comprising:

• means for generating a sound in a first frequency range within the audible frequency range and a second frequency range that ranges from above a predetermined audible frequency range to a predetermined maximum frequency, wherein said generated sound in the second frequency range is in a non-stationary state so as to change in a micro-temporal area in a second frequency range above 10 kHz;
• means for applying first sound components of said sound in the first frequency range directly to an auditory sensation of a person, said means for applying first sound components comprising a pair of earphones;
• and
• a loudspeaker applying second sound components that are above the audible frequency range substantially throughout the entire body of said person, for increasing cerebral blood flow of the person as indicated by increased α-EEG activity of the person's brain, wherein the non-stationary state characteristic of the generated sound is required for generating a hyper sonic effect to increase α-EEG activity of the person's brain in an effort to reduce human stress.

A sound generating space comprising:

• means for generating a sound in a first frequency range within the audible frequency range and a second frequency range that ranges from above a predetermined audible frequency range to a predetermined maximum frequency, wherein said generated sound in said second frequency range is in a non-stationary state so as to change in a micro-temporal area in a second frequency range above 10 kHz;
• means for applying first sound components of said sound in the first frequency range directly to an auditory sensation of a person, said means for applying first sound components including a pair of earphones;
• and
• loudspeaker applying second sound components that are above the audible frequency range substantially throughout the entire body of said person, for increasing cerebral blood flow of the person as indicated by increased α-EEG activity of the person's brain, wherein the non-stationary state characteristic of the generated sound is required for generating a hyper sonic effect to increase α-EEG activity of the person's brain in an effort to reduce human stress.

A method for generating a sound, comprising:

• applying first sound components of said sound in the first frequency range directly to an auditory sensation of a person through a pair of earphones;
• and
• applying second sound components that are above the audible frequency range substantially throughout the entire body of said person through a loudspeaker, for increasing cerebral blood flow of the person as indicated by increased α-EEG activity of the person's brain, wherein the non-stationary state characteristic of the generated sound is required for generating a hyper sonic effect to increase α-EEG activity of the person's brain in an effort to reduce human stress.
