ABSTRACT:
In a sound generating apparatus, a sound generating space, a sound, and a method for generating a sound, a sound is generated which has a frequency within a first frequency range beyond a predetermined audible frequency range and up to a predetermined maximum frequency, and which is non-stationary so as to change in a micro-temporal area in a second frequency range beyond 10 kHz. Then, the generated sound is applied to a person, thereby increasing cerebral blood flows of the person. This causes improvement and enhancement of the person's state of mind and body, so as to relieve stresses, thereby relaxing the person.
