Abstract:
Objective The aim of this study is to analyze the relationship between the development of audito‐ry and speech in infants with hearing loss after hearing aid fitting and discuss the development of speech with the a‐bility of auditory in infants with different degree of hearing loss and different stage of evaluation after hearing aid fit‐ting .Methods A total of 32 infants (17 boys and 15 girls) with prelingual hearing loss participated in this study . The age at hearing aid fitting ranged from 3 to 34 months with a mean of 15 .6 months .According to their hearing level ,all infants in this study were divided into three groups :group of profound hearing loss(16) ,group of severe hearing loss(11) ,group of moderate hearing loss(5) .CAP and SIR were used to evaluate their abilities of auditory and speech at pre -fitting ,1 ,3 ,6 ,9 and 12 months after hearing aid fitting respectively .A linear and regression a‐nalysis was done in the statistic procedure .Results There was a significant correlation between the scores of CAP and SIR for the three groups respectively .The correlation from low to high followed by the group of profound hear‐ing loss (R=0 .656 ,P=0 .000<0 .05) ,group of severe hearing loss (R=0 .758 ,P=0 .000<0 .05) ,group of mod‐erate hearing loss (R=0 .849 ,P=0 .000<0 .05) .There was also a significant correlation between the scores of CAP and SIR for the different evaluating stages respectively .The correlation from low to high followed by pre -fitting (R=0 .559 ,P=0 .000<0 .05) ,1 month after hearing aid fitting (R=0 .575 ,P=0 .000<0 .05) ,3 months after hearing aid fitting (R=0 .726 ,P=0 .000<0 .05) ,6 months after hearing aid fitting (R=0 .823 ,P=0 .000<0 .05) , 9 months after hearing aid fitting (R=0 .838 ,P=0 .000<0 .05) ,12 months after hearing aid fitting (R=0 .855 ,P=0 .000<0 .05) .Conclusion The development of auditory ability is closely related to speech ability which increases with the improvement of auditory ability .The less the infants have the hearing loss and the longer the infants use the hearing aids ,the higher the auditory ability is related to speech ability in infants after hearing aid fitting .
