Definitions

  • ⁇ effect> since the frequency of the beat sound is determined by grasping the current electroencephalogram state of the individual user, the effect of synchronizing the target electroencephalogram band is high. In addition, since the surrounding environmental sound itself is not pitch-shifted, but a binaural beat noise signal is mixed, the user does not feel uncomfortable.
  • ⁇ Sound emitting unit 23> Input: Collected environmental sound converted into binaural beats based on the user's optimum beat sound frequency
  • the sound emitting unit 23 may emit sound such that one of the two binaural beat signals, that is, the two signals with different frequencies, reaches the left ear and the other signal reaches the right ear, or the frequency It is also possible to monauralize the two signals with different values, and emit the monauralized signals so as to reach the left and right ears.
  • the external storage device of the hardware entity stores a program necessary for realizing the functions described above and data required for the processing of this program (not limited to the external storage device; It may be stored in a ROM, which is a dedicated storage device). Data obtained by processing these programs are appropriately stored in a RAM, an external storage device, or the like.
  • each program stored in an external storage device or ROM, etc.
  • the data necessary for processing each program are read into the memory as needed, and interpreted, executed and processed by the CPU as appropriate.
  • the CPU realizes a predetermined function (each component expressed as above, . . . unit, . . . means, etc.).
  • this program is carried out, for example, by selling, assigning, lending, etc. portable recording media such as DVDs and CD-ROMs on which the program is recorded.
  • the program may be distributed by storing the program in the storage device of the server computer and transferring the program from the server computer to other computers via the network.
  • a hardware entity is configured by executing a predetermined program on a computer, but at least part of these processing contents may be implemented by hardware.
