بررسی اثرات تربیت شنوایی بر فرآیند رشد گفتار و زبان کودکان ناشنوای زیر 7 سال شهر همدان در سال 1378

          Hearing loss in critical ages or before it often leads to serious damage to    the lingual and verbal ability in children. It causes limitation , sensational    problems and disability in communication and consequently creates    isolation , depression sociopsycological and emotional problems. Therefore    it is necessary to help a child to experience hearing , systemically and be    able to hear sounds easier and also to distinguish between them. We are    able to achieve this goal by auditory training program , consequently one    will be able to use his  remains of hearing ability for sound perception in the    best way.           In this experimental study 52 deaf children (under the age of 7 years)    were studied in Hamadan . They were divided in two groups , each consist    of 26 children on the basis of their IQ and the degree of loss of hearing. In    test group the children were familiarized with sign communication method    and also with verbal communication method, while children in control    group only used sign language for communication and they had no    information about verbal communication method.            The research findings showed implication of auditory training program    caused lingual and verbal development in children under 7 year in    Hamadan. Children with more hearing remains had better verbal lingual    growth than those with less hearing remains. Also there was no relation    between sex and age  and verbal lingual growth in this group. In other word    familiarity with verbal communication method is the main factor for verbal    lingual growth in this group.           Finding revealed that after administering auditory training program ,    distinguishing and identifying verbal and nonverbal method developed    better than control group.
