title: Some relationships between hearing aid frequency response and speech discrimination of profoundly deaf children. Pilot study.
abstract: A significant improvement in auditory-visual speech discrimination has been established for a group of profoundly deaf children with hearing losses in the range from 85 to 120 dB HL (pure tone average (500, 1,000, 2,000 Hz] by increasing the low frequency hearing aid gain by approximately 10 dB and reducing the high frequency gain by approximately the same magnitude. The improvements were concentrated in the hearing loss range from 95 to 115 dB HL. A tendency for improvement in auditory discrimination was indicated as well.
