Abstract

<p>　The LENA (Language ENvironment Analysis) system measures the quantity of spoken language in a child's environment by means of a small wearable digital recorder and processing software. The purpose of the present study was to evaluate the performance of the LENA system for the Japanese language environment. Our study focused on three groups of participants: (1) 5 children with normal hearing (1 male and 4 females, 10-40 months old); (2) 2 children with congenital profound hearing loss who had undergone cochlear implantation (CI) (2 males, CI at 2 years 9 months old and 3 years 4 months old); (3) elderly adults with hearing impairment (3 males, 4 females; 75-88 years old). Recording and analysis using the LENA system was possible for all participants. The auditory environment of the children with normal hearing children and those with hearing loss were similar, while TV time was much longer in elderly adults with hearing loss as compared to either group of children. The quantities of spoken language, such as adult word counts, child vocalizations and conversational turns in the Japanese environment could also be evaluated. Further investigation of the normal Japanese environment versus the English environment using the LENA system is necessary.</p>
