The hearing disorder in infants is often acco-mpanied by retarded speech, mental retardation, and other physical defect. And the examinationon the patients having these troubles is verydifficult to be performed. On the other hand, the relation between these troubles and their hearing disrders is unknown.In this paper, to know the state of hearing disorders in infants, some methods of audiometry for infantile patients were discussed and the etio-logic circumstances of them were studied. Moreo-ver, the interrelation of hearing disorder and mcn-tal retardation was investigated. In the first chapter, the reliability and pos-sibility of the audiometry for infants were discus-sed and the hearing threshold of normal infantswas measured. In the second, the etiologic observations have been done upon the hearing disordered infans in some regions, and then, the state of them was discussed. In the third, the interrelation of infantile hea-ring disorder and mental retardation or cerebral paralysis was studied. It comes to the conclusion that these disordered infants are sometimes treated indiscriminately and conceptually. Moreover, the contents of infantile disorders such as hearing impairment, retarded speech, mental retardation, and cerebral paralysis etc. were sometimes not confirmed. It is the fact that infantile hearing disorders have some influen-ces upon the development of speech or intelligence-however, in this report, it is advocated that there is no interrelation between inner deafness and essen-tial mental retardation, especially between hearing disorder and mental deficiency.
