CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a Divisional application of application Ser. No. 10/743,789, filed on Dec. 24, 2003, which is a Divisional application of application Ser. No. 09/159,104, filed on Sep. 23, 1998, the entire disclosures of which are hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] The present invention relates to an auditory sense training method and sound processing method for auditory sense training which realizes an effective training for the great improvement of auditory perception, which is an obstacle to a person grown in an environment having a different language practice from learning another language or music of a different language environment. [0003] Further, the present invention relates to an auditory sense training method and sound processing method for auditory sense training which may be used in medical areas such as the treatment for hypacusia and tinnitus, or music treatment. [Regarding Auditory Sense] [0004] The auditory sense of a person does not have a structure common to everyone, but rather, the structure of the auditory sense could be characterized by the language the person is using in their daily life. In other words, the structure of a person's auditory sense is advanced so that it works conveniently when listening to the language they use in their daily life. [0005] In this specification, the structure of an auditory sense refers to the structure including the recognition ability of a vowel or a consonant, or the recognition ability of the attenuation of a tone and the like. [0006] It is very rare in the Japanese language to end a word or a sentence by a consonant including many high frequency components of above 200 Hz for example. Rather, it ends by attenuating a vowel including many low frequency components. [0007] Further, according to studies, it is now known that the Japanese especially sensitively percepts a vowel in a voice, and as a very special phenomenon, the Japanese are very sensitive to the reverbaration included in a vowel (reverbaration is likely to remain when the frequency is low). [0008] These characteristics on the frequency band of the Japanese language and the sensitiveness of the Japanese native to the reverbaration sound or the attenuation sound show that the Japanese have a tendency to concentrate on the sound in the ending of a word. [0009] That is, to a Japanese user, a peculiar or unique auditory sense structure which is appropriate for listening to and speaking Japanese is formed. Therefore, a voice which falls out of the peculiar auditory sense structure, for example, with a frequency component of above 2000 Hz, could not be recognized easily, and there is a tendency that the language having different pronunciation forms or grammar structure is hard to recognize. [0010] Moreover, aging is another cause which makes it difficult for a person to recognize voice having high frequency regions. [0011] On the other hand, in European languages such as English, German and Latin, high frequency components of over 2000 Hz are largely included, and some components even reach up to 6000 Hz. [0012] That is, the language characteristics of an European language is opposite to Japanese in that the vowels only hold a dependent meaning, and that the recognition of the energy, the rising condition and the depth included in a consonant or the way to cut the consonant in the ending of a word is most important in recognizing the language. Moreover, the intonation, the strength, the accent and the like related to the grammar is important in recognizing the language. This could also be recognized from the fact that the native European language speakers are able to recognize the conversation of their language even by listening to voices whose frequency components of under 2000 Hz are reduced. [0013] From the above mentioned fact, it could be seen that the Japanese have a tendency to recognize a vowel which does not exist, but on the other hand, may not recognize an existing consonant. [0014] For example, the Japanese are known to have a low ability to recognize the rising of a consonant or to tell the high frequency components in a sound. One known example is that the Japanese have a low ability to tell the difference between the consonant of "L" and "R" or "M" and "N" in English. [0015] Further, they recognize the word "McDonald" as "makudonarudo", and "Seven Eleven" as "sebun irebun", and pronounce such words by adding vowels. [0016] That is, the above-mentioned words pronounced by the Japanese speaker is constituted according to the auditory sense structure of the Japanese language. [0017] If the ability to recognize the rising of a consonant or to tell the high frequency components in a sound is low, the ability to pronounce the rising of a consonant or the high frequency components in a sound is also very low. [0018] Therefore, according to the Japanese auditory sense structure mentioned above, it is difficult to either hear the language having a different language practice accurately or to pronounce such language as the native speakers. [0019] In order to understand the structure of the auditory sense according to the Japanese language, the inventor performed an experiment where native Japanese speakers listened repeatedly to a voice processed to reduce its low frequency components and to strengthen a specific frequency band component, and came to the following conclusion. [0020] Moreover, as a result of continuous experiment, a data was gained where the auditory sense would quickly switch back to the auditory structure as a Japanese native speaker when an unprocessed language is heard instead of the processed language. [0021] Accordingly, it could be understood that in the auditory sense structure, the "recognition frequency" differs according to national, in other words, an "unrecognized frequency" exists according to national even if their tympanum may vibrate.
