The Effectiveness of Low-Frequency Amplification and Filtered-Speech Testing for Preschool Deaf Children.
Asp, Carl W.
In order to study effectiveness of low-frequency amplification and filtered-speech testing for preschool deaf children, an experimental design permitting the teacher to speak simultaneously through two different amplifying systems, a low-frequency auditory training unit (Suvag I) and a conventional auditory training unit (Warren T-2), was used with 30 children. All teachers utilized the Verbo-tonal Method for habilitating the children, who were assigned to one of the two amplifying systems. Speech samples were tape-recorded at 4-month intervals, judged, and analyzed statistically. Significant improvement over testing times for both groups was found, although the Suvag group demonstrated a greater rate of improvement than the Warren group. The condition of visual and auditory clues with amplification was reported to be the best experimental condition for most children. Significant differences between the groups in terms of vocalization was found, with the Suvag group vocalizing more times per minute than the Warren group. Significant correlation was also reported between rating value and hearing level. Electrical and acoustic responses of the Suvag I unit indicated that the unit passed more low-frequency energy than the Warren unit. Reporting of related research concluded the interim report.
