Abstract

The most commonly used method of stimulating the human brain is the auditory method. Among the auditory stimulating methods, the effective method is the binaural beat, which is used to induce specific brain waves in humans. It is used to change the physical and mental state of humans according to the type of brain waves induced.

According to the present invention, it is proposed to develop an MP3 player having a function of inducing a specific brain wave by developing a binaural beat into an MP3 file and mounting it on the MP3 player.

Description

MP3 Player with Brain Wave Induction Function {A MP3 Player Developing Human EEG}

A type of auditory stimulus currently used to stimulate the human brain is called binaural beats. Binaural beats are two types of sounds that have a specific frequency difference in both ears. This method is based on the characteristic that EEG is induced corresponding to the frequency difference of.

Hearing stimulation methods are also used for medical purposes, and a company called Limddonna, Germany, has demonstrated that sound in the audible frequency band can be stored in analog form, reproduced through speakers, and stimulate the human brain. This sound proved to maintain its effect even when it is provided with background sound, that is, music. The source was developed using a high frequency generator.

The present invention proposes an MP3 player having a function of inducing human brain waves of a specific frequency and a method of configuring the same.

Among the digital signals used in computers, sounds with auditory stimulus function are implemented and reproduced in the audible frequency band, that is, 20 to 20000 hertz band, and if it is out of this frequency band, additional equipment must be added. have.

In order to overcome this problem, we have to understand the characteristics of the frequency, 100 hertz means to have 100 frequencies per second, and the audible frequency must have a frequency of between 20 and 20,000 times. do.

However, for example, the sound of 1000 hertz has 1000 frequency per second, but if the playback speed of this sound, which is 10 seconds long, is 10 times faster, the sound of 10000 hertz is played in 1 second. The sound is recognized as a sound stimulus of 10000 hertz, which is characterized by converting the frequency of the sound by changing the time axis, that is, the playback speed, when the sound is composed of the frequency axis and the time axis.

This is the principle that the sound itself is distorted like a high frequency when the human voice is recorded and the playback speed is increased, which stimulates the human ear. It becomes possible.

That is, if the playback speed of the original sound with the frequency of 1000 hertz is 10 times faster, it is reproduced with the sound of 10000 hertz, and if the playback speed of the 1000 hertz sound is doubled, the sound is 500 hertz, so more accurate sound source can be realized. Will be done.

In this method, it is easier to manage and manage the original source and to develop a new source. When developing a source, and developing and playing the source in an audible frequency band, there is no need for a sound generator when developing the source. You have an advantage.

In addition, in order to play a variety of sound sources in order to develop products using binaural beats, several types of sound sources must be stored in the hardware. Depending on the type of sound source, it can be used as a sound source.

The range of application of the sound source can be generally used in computers, MP3 players, CD players, audio players, electronic dictionaries, game consoles, learners such as brain wave guides, sleep guides, stress relievers, etc. Has both ear and headphone functions, and a technology for presenting two different sound stimuli to both ears one by one is already commercially available.

Here, the EEG-induced learner auditively presents binaural beats that can induce low beta waves related to human concentration in the course of the user's learning, and low beta waves are induced. Since EEG is expressed in, maintaining a low beta wave state is to maintain the concentration of human.

However, until now, such a function has been implemented only in a dedicated learning inducer, and has not been implemented in MP3 Player. Therefore, to apply the binaural beat in the form of wave file to MP3 Player, If you develop a MP3 file, mount it on MP3 player, and program it to provide the beat sound to the user, you can use the function that can induce the brain wave desired by the user through simple operation.

Here, in case of theta waves, brain waves appearing in the sleeping state, so the use of binaural beats that can induce theta waves can provide a comfortable sleep state to insomnia patients, and in the case of alpha waves, the brain waves are expressed in the resting state. Therefore, it is effective when used to relieve stress or to relieve tiredness, and when using binaural beats that can induce low beta waves, it is possible to improve the learning ability by enhancing the concentration of the user.

The most important thing here is in earphones or headphones that use binaural beats attached to both ears, and it is important to provide a sound signal with two different frequency differences to each earphone, which is already commercially available. Way.

Since the sound of the original sound source developed through the present invention can be utilized in various forms through only a simple method of changing the playback speed, it is possible to solve the technical problems of developing various sound sources in the development of sound sources. There is an effect that can be overcome, and in the case of MP3 Player, there is an effect that can provide a way to provide the ability to develop the human brain in addition to the function of the classic MP3 Player.

1 is a sound frequency conversion method according to the present invention

* Explanation of the sign

1-1: audible frequency sound in the 2100 hertz band having a length of 10 seconds, 1-2: a method of converting the sound into a 21000 hertz by reproducing a sound of 10 seconds per second by 10 times faster the playback speed of 1-1, 2-1: The same sound source as 1-1, 2-2: How to play 1-2 times in the same long length sound as the original source
