Abstract
There is a considerable debate on the use of hearing aid in children with auditory dys-synchrony (AD). To current date there are no similar Studies which show the effect of acoustic amplification on outcomes on speech and language development in children with AD are found in the literature. Thus, in the present study three children diagnosed to have AD were recruited and subjected to hearing aid trial and fitting based on the late latency response thresholds. Ranging from 7 months to 41 months of intervention period, each child’s language age was reassessed and compared with that of their pre-therapy language age. The comparison showed a good improvement in receptive age, though the children had moderate to severe degree of hearing loss. But their expressive age was significantly delayed irrespective of their age of identification and duration of intervention. Thus the delay in expression with a good amount of improvement in reception can be a characteristic of an AD child with amplification.

Summary
There is a considerable debate on the use of hearing aid in children and their speech recognition abilities show no correlation with the with auditory dys-synchrony (AD). To current date there are no similar degree of hearing loss.[1] Difficulty in speech recognition extends to Studies which show the effect of acoustic amplification on outcomes greater impairment in presence of noise due to poor temporal processon speech and language development in children with AD are found in the literature. The comparison showed a good improvement in receptive age, though e the children had moderate to severe degree of hearing loss. Their s expressive age was significantly delayed irrespective of their age of u identification and duration of intervention.
