The Effectiveness of Low-Frequency Amplification and Filtered-Speech Testing for Preschool Deaf Children. Final Report.
Asp, Carl W.
During a 3-year period, 20 preschool deaf children were matched and given auditory training by the Verbo-tonal method using two different amplification systems (one which amplified from 200 to 5000 hertz and the other from 20 to 5000 hertz). There were three main goals: (1) to compare two different amplification systems to determine if the addition of frequencies in the 20 to 200 hertz range could facilitate the acquisition of speech perception and speech production skills in young deaf children; (2) to evaluate if severely impaired children could be trained auditorily by using aural/oral procedures such as the Verbo-tonal method; and (3) to evaluate filtered-speech testing for young deaf children. There was no significant difference between the speech reception/production scores of the two groups. Both groups showed significant improvement, indicating that the verbo-tonal method was effective in the auditory training of severely hearing-impaired children. The filtered speech testing produced similar detection thresholds to those of pure-tone audiometry. (Appendixes include a review of literature on the use of low-frequency amplification with the hearing impaired, a Verbo-tonal method materials list, and a curriculum guide for using the Verbo-tonal method.)
