Abstract
-
Three experiments were conducted to investigate the feasibility of using a paired-comparison technique to select hearing aids for children. Experiment 1 determined the age at which 5 out of 5 normal-hearing children were able to pass a paired-comparison test involving judgments of auditory clarity. Twenty-five normal-hearing children between the ages of 4.0 and 6.5 years were tested. Five age groups were formed with 5 subjects per group. The results showed that all 5 children between the ages of 6.0 and 6.4 years passed the auditory paired-comparison test.;Experiment 2 determined the age at which 5 out of 5 hearing-impaired children were able to pass a paired-comparison test involving judgments of auditory clarity. Ten children with mild to moderately-severe sensorineural hearing loss were tested. Their ages ranged between 5.5 and 7.4 years. Two age groups were formed with 5 subjects per group; 5.5 to 6.4 years, and 6.5 to 7.4 years. The results showed that all 5 hearing-impaired children between the ages of 6.5 and 7.4 years passed the auditory paired-comparison test.;Experiment 3 investigated whether a paired-comparison technique could be used effectively to select hearing aids for hearing-impaired children capable of performing an auditory paired-comparison task. Eight hearing-impaired children between the ages of 5.7 and 7.8 years judged the clarity of seven hearing aid, frequency-gain shapes in two paired-comparison tournaments. Phoneme identification scores were also obtained for each shape.;The results showed that correlations between the two tournaments were moderate to strong for 6 children and weak for 2 children. Of the 6 children who demonstrated good reliability, correlations between paired-comparison judgments and phoneme identification scores were moderately strong for 3 children and weak to moderate for 3 children. The hearing aid selected by the paired-comparison technique did not degrade speech intelligibility when compared with a standard prescription. Results from this study indicate that a paired-comparison technique can be used reliably to select hearing aids for some hearing-impaired children who are 6.5 years of age and occasionally younger.
