According to an article in AAP News, children with permanent hearing loss developed better language skills the earlier they started interventions, researchers found.
The impact was especially true for those with worse hearing, according to the study, “Age at Intervention for Permanent Hearing Loss and 5-year Language Outcomes.” Roughly one to two of every 1,000 newborns experience bilateral permanent childhood hearing loss (PCHL). AAP Early Hearing Detection and Intervention guidelines call for screening by 1 month of age, diagnosis of hearing loss by 3 months of age, and early intervention services by 6 months.
To look more closely at interventions, researchers studied 350 children in Australia with PCHL who had received a hearing aid or cochlear implant by age 3. They compared the group to 120 children with normal hearing. At age 5 or 6, children were tested on their language and communication skills by a speech pathologist. Parents also described their children’s language skills. Children who started amplification at 3 months had significantly better language skills than those who started at 24 months, according to the study. Those with 70 decibel hearing level benefited even more than those with 50 decibel hearing level.
