Repeated impedance measures were given over five weeks to 11 autistic, 20 learning-disabled, and 20 normal children. A repeated measures analysis of variance led to the conclusion that fluctuating, negative middle ear pressure greater than normal characterizes both autistic and learning-disabled children with the more abnormal pressures typical in…

Long-term effects on auditory electrophysiology from early fluctuating hearing loss were studied in 27 children, aged 5 to 7 years, who had been evaluated originally in infancy. Findings suggested that early fluctuating hearing loss disrupts later auditory brain stem electrophysiology. (Author/DB)

Temporal envelope and spectral cue resolution were evaluated simultaneously in seven adults with severe/profound hearing impairments. Results revealed that the Auditory Numbers Test (ANT) is differentially sensitive to responses based upon gross temporal envelope and spectral cues in the speech signal. The ANT is endorsed as a screening tool for…

The hearing ability and related cognitive ability of 26 adolescents and young adults with Down's Syndrome (DS) and 26 matched subjects with trainable mental retardation (MR) were compared. Results revealed greater hearing losses in DS than in other MR individuals, especially in the high-frequency range. DS subjects with poorer hearing needed more…
