A simple auditory test has been developed to assist in determing whether a young hearing-impaired child can perceive spectral aspects of speech or only gross time/intensity acoustic patterns. This recorded tape-cards test required the child with optimum hearing aid to identify counted sequences and individual numbers. It was administered to 53 children (96 ears), 4-11 years old, with mean hearing levels (500, 1000, 2000Hz) at 75-133dB. As the results, scores were related to mean HL, and generally the scores were high for mean hearing levels better than 90dB and low for hearing levels poorer than approximately 113dB. Although a range from minimum to maximum was obtained for children with audiograms at 91-111dB. Their audiogram could be inadequate for diagnostic purpose of listening skills.
The Japanese Auditory Number Test (JANT) is recommended for practical evaluation of listening skills and speech perception in young hearing impaired children to aid in the planning of an auditory training program.
