The Effectiveness of Low-Frequency Amplification and Filtered-Speech Testing for Pre-School Deaf Children. Interim Report [electronic resource] / Carl W. Asp.
To evaluate the effectiveness of low-frequency amplification, three classrooms were equipped in an experimental design in which the teacher spoke simultaneously through two different amplifying systems, a low-frequency auditory training unit (Suvag I) and a conventional unit (Warren T-2). Thirty pre...

| 520 | |a To evaluate the effectiveness of low-frequency amplification, three classrooms were equipped in an experimental design in which the teacher spoke simultaneously through two different amplifying systems, a low-frequency auditory training unit (Suvag I) and a conventional unit (Warren T-2). Thirty preschool deaf children were matched and assigned to either unit. The same type of output transducers were utilized for all the children. Teachers used the Verbo-tonal Method (primarily an auditory program) for habilitation. The low-frequency unit produced a greater acoustic response below 500 Hz. Hearing aids were selected that produced frequency responses similar to the training units (the Mini Suvag for children on the low-frequency unit, the Zenith Vocalizer II for the conventional unit). A Bruel and Kjaer test system was used to evaluate the training units and hearing aids. The Mini Suvag, capable of simultaneously driving a vibrator and a headset, had a greater low-frequency response. (KW) | ||
