The mixing device 24 generates the input sound signal h for the left ear, receives the audio signal c, receives the audio signal a2 adjusted by the variable resistor 28, and outputs the audio signal c and the audio signal a2. To generate an input original sound signal i for the right ear.

Next, the first and second specific frequency band emphasizing circuits 21 and 22 will be described. Since the structures of the first and second specific frequency band emphasizing circuits 21 and 22 are the same, only the first specific frequency band emphasizing circuit 21 will be described.

As shown in FIG. 2, the first specific frequency band emphasizing circuit 21 includes a selection switch 31 as specific frequency band selecting means, and first and second selecting means as first and second emphasized signal waveform setting means. It has two filter circuits 32 and 33 and a gain switching circuit 34 as level changing means. The selection switch 31 is formed by a slide switch, and includes a movable terminal t1 and fixed terminals t2 to t4.
The movable terminal t1 is moved by manually operating a specific frequency band selection switch (not shown) by the subject and placing the movable terminal t1 at the first to third specific frequency band selection positions, and selectively contacts the fixed terminals t2 to t4. Let me do.

The movable terminal t1 and the fixed terminal t2
Is contacted, the input original sound signal h is output as it is, and when the movable terminal t1 and the fixed terminal t3 are contacted, the input original sound signal h is sent to the first filter circuit 32, and By the first filter circuit 32,
In the present embodiment, in the first frequency band of the audio signal b, the amplitude of the frequency component of 1500 to 5000 [Hz] is increased to become the first emphasized signal waveform k1,
When the movable terminal t1 and the fixed terminal t4 are brought into contact with each other, the input original sound signal h is sent to a second filter circuit 33, and the second filter circuit 33 causes the second frequency band in the acoustic signal b to be changed. However, in the present embodiment, the amplitude of the frequency component of 3000 to 5000 [Hz] is increased to become the second emphasized signal waveform k2.

Therefore, by operating the selection switch 31, the frequency band is selected in accordance with the proficiency of the foreign language, and when the auditory training is started, the specific frequency band selection switch is set to the third specific frequency band. By selecting the second frequency band by placing it in the selected position, and placing the specific frequency band selection switch in the second specific frequency band selecting position as the proficiency increases,
If you select the first frequency band and become more proficient,
By placing the specific frequency band selection switch at the first specific frequency band selection position, the frequency component of the audio signal a can be prevented from being emphasized.

The gain switching circuit 34 includes a resistor R1 connected to the output side of the first and second filter circuits 32 and 33.
To R3 and a selection switch 35.
5 is switched by the subject manually operating a level selection switch (not shown) and placing the level selection switch in the first to third gain selection positions, and the first and second filter circuits 32, 3
3, the resistors R1 to R3 are selectively connected. When the resistor R1 is connected to the output side of the first and second filter circuits 32 and 33, the first and second emphasized signal waveforms k1 and k1
The gain of k2 is set to 6 [dB], which is the first level,
When the resistor R2 is connected, the gain is set to the second level of 10 [dB], and when the resistor R3 is connected, the gain is set to the third level of 14 [dB]. In this case, when the gain is selected in accordance with the proficiency level of the foreign language and the auditory training is started, the third level is selected by setting the level selection switch to the third gain selection position, and the proficiency level is selected. By setting the level selection switch to the second gain selection position as the degree increases, the second level is selected.

As described above, the gains of the first and second emphasized signal waveforms k1 and k2 are switched by the gain switching circuit 34, and the first and second emphasized signal waveforms k1 and k2 are amplified and the first and second emphasized signal waveforms k1 and k2 are amplified. From the specific frequency band emphasizing circuit 21
Is output.

Similarly, the second specific frequency band emphasizing circuit 2
2, when the input original sound signal i is input to the second specific frequency band emphasizing circuit 22, the frequency component of the specific frequency band in the acoustic signal c is emphasized in the second specific frequency band emphasizing circuit 22. Two specific frequency band emphasized signals m are output.

By the way, languages unique to different regions, for example, a frequency band to which a foreign language belongs and a frequency band to which a native language belongs are different. For example, in Japanese, a word or a phrase rarely ends with a consonant including many high frequency components of 1500 [Hz] or more, whereas in English, German, French, and the like, the word or phrase is 1500 [Hz].
It often ends with a consonant containing many high frequency components of [Hz] or more.

However, the first of the acoustic signals b and c,
Since the frequency component in the second frequency band is emphasized, when the processed sound generated by the headphones 13 is heard, the sound of the high frequency component in the processed sound can be focused and the hearing can be awakened. Therefore, since the auditory sense can be trained based on the unique structure of the foreign language, a sufficient training effect can be obtained. As a result, it becomes easier to learn a foreign language.

Next, the right brain stimulating function section 16 will be described.

As shown in FIG. 1, the right brain stimulating function unit 1
6 is a vowel algorithm 41 as a vowel detection means for detecting a vowel in the audio signal a based on the frequency, a changeover switch 42, an LED 43 as a vowel detection display means,
And an emphasis device 44 as right brain stimulation signal generating means for emphasizing the audio signal a2. The changeover switch 42 has terminals t11 to t13. Normally, terminals t11, t1
3 are connected, the terminals t11 and t12 are connected at the timing when the vowel is detected by the vowel algorithm 41, and the audio signal a2 is sent to the emphasis device 44. Since the vowel has a frequency component of about 200 [Hz], the vowel algorithm 41 determines that the audio signal a1
Vowels are detected based on whether they fall within a predetermined range centered at [Hz].

By the way, Westerners recognize vowels in the right brain, whereas Japanese people recognize vowels in the left brain, so it is considered that the vowel recognition function in the Japanese right brain is low. Therefore, in the present invention, the right brain stimulating function unit 1
6 stimulates the right brain.

For this purpose, the vowel algorithm 41
Receives and monitors the audio signal a1 from the amplifier 27, and sends the audio signal a2 to the emphasizing device 44 at a timing when a vowel is detected. Then, the emphasis device 44 outputs the audio signal a
2 to generate a right brain stimulation signal g for stimulating the right brain. In the present embodiment, in order to emphasize the audio signal a2, the emphasizing device 44 determines whether the audio signal a2 has a 1000
The amplitude of a high frequency component higher than [Hz] is increased.

The right brain stimulation signal g is supplied to the mixing device 2
3 is mixed with the acoustic signal b to become an input original sound signal h and sent to the first specific frequency band emphasizing circuit 21, where the first and second specific frequency band emphasizing circuits 21
The amplitudes of the frequency components of the first and second frequency bands in the audio signal b are increased by the filter circuits 32 and 33 to generate first and second emphasized signal waveforms k1 and k2. As described above, the first specific frequency band emphasizing circuit 21 generates the first specific frequency band emphasizing signal j based on the acoustic signal b and the right brain stimulation signal g.

Therefore, each time a vowel is detected, the right brain is stimulated and activated, so that the vowel recognition function is enhanced. In this case, since the right brain stimulation signal g is mixed with the acoustic signal b in the mixing device 23, the right brain is directly stimulated through the left ear.

Further, since the amplitude of the predetermined frequency component is increased in order to emphasize the audio signal a2, it is possible to prevent the waveform of the right brain stimulation signal g from being distorted. Moreover, since the input original sound signal h is generated by mixing the right brain stimulation signal g and the acoustic signal b, it is possible to prevent the distortion of the waveform of the input original sound signal h. Accordingly, it is possible to prevent the waveform of the finally obtained output signal d from being distorted, so that it is possible to increase the impact on the processed sound when training the auditory sense.

Next, the right ear hearing enhancement function unit 17 will be described.

As shown in FIG. 1, the right ear hearing enhancement function unit 17 includes a pulse generator 46 and a right channel enhancement device 47 as right ear hearing enhancement signal generating means.
The second specific frequency band emphasis signal m generated by the specific frequency band emphasis circuit 22 is selectively emphasized, the amplitude is increased at a constant period, and the right ear hearing enhancement signal is used to enhance the right ear hearing. Of the second specific frequency band emphasized signal n
To For this purpose, the pulse generator 46 generates a pulse at a constant cycle, for example, 0.5 [sec] cycle,
The pulse is sent to the right channel enhancer 47. The right channel emphasizing device 47 sets the amplitude of the second specific frequency band emphasizing signal m to 50% when the pulse is transmitted.
Enlarge.

Thus, the hearing of the right ear can be enhanced through the output signal e. Since the sound information based on the processed sound is transmitted to the left brain, the processing in the brain can be accelerated. In addition, since the amplitude of the second specific frequency band emphasis signal m is increased in order to emphasize the second specific frequency band emphasis signal m, the waveform of the second specific frequency band emphasis signal n is distorted. Can be prevented. Accordingly, it is possible to prevent the waveform of the finally obtained output signal d from being distorted, so that it is possible to increase the impact on the processed sound when training the auditory sense.

Reference numeral 48 denotes a first mode selection switch. By switching the mode selection switch 48, the right ear hearing enhancement function mode and the normal mode can be selected. The second specific frequency band emphasis signal m is sent to the right channel emphasis device 47 when the right ear hearing enhancement function mode is selected, and bypasses the right channel emphasis device 47 when the normal mode is selected. And sent to the brain activation function unit 18.

Generate p and q. In the present embodiment, the amplitude of a high frequency component of 4500 [Hz] or more is increased at a constant cycle.

The second mode selection switch 5
By switching the mode 3, the language mode and the music mode can be selected. When the language mode is selected, the language pulse generator 51
A first pulse is generated at a [sec] cycle, and the first pulse is sent to the first and second high-frequency emphasizing devices 54 and 55 via the second mode selection switch 53, and the music mode is selected. Then, the music pulse generator 52 performs the second
Of the first and second high-frequency emphasizing devices 5 through the second mode selection switch 53.
4, send to 55. Therefore, the first specific frequency band emphasis signal j can be used for learning a foreign language and listening to music.
In addition, it is possible to change the period for emphasizing high frequency components in the second specific frequency band emphasis signals m and n.
When the first specific frequency band emphasis signal j and the second specific frequency band emphasis signals m and n are emphasized in a 0.5 [sec] cycle, they are emphasized in quadruple.

The first and second high-frequency emphasizing devices 54
In 55, the rate of change of the amplitude, that is, the degree of emphasis is set differently for each frequency component. For example, 45
In the case of a frequency component of 00 [Hz], the degree of emphasis is set to 5 [%]. In the case of a frequency component of 5000 [Hz], the degree of emphasis is set to 10 [%]. In the case of a frequency component of 6000 [Hz], The degree of emphasis is set to 25%, and 8000 Hz to 1
In the case of a frequency component of 0 [kHz], the emphasis degree is 30 [%].
In the case of a frequency component of 15 [kHz], the emphasis level is set to 28 [%]. In the case of a frequency component of 20 [kHz], the emphasis level is set to 20 [%], and the frequency component of 30 [kHz]. In this case, the degree of emphasis is set to 8 [%]. in this case,
The first and second high-frequency emphasizing devices 54 and 55 are 12 [dB] /

The remaining can be suppressed. Therefore, since the waveform of the frequency component of 1500 to 5000 [Hz] can be made flat,
