Ninetieth percentile cutoffs for acoustic reflex thresholds (ART) were determined for a sample of 1,374 adult subjects with normal hearing and sensorineural loss of cochlear origin. It was found that 12.2 percent had one ear ART elevated above the ninetieth percentile, but only 5.6 percent had more than one elevated ART. (DB)

Occlusion effects were determined and compared on three groups of subjects (20 normal hearers, 20 with conductive hearing loss, and 20 with sensorineural hearing loss). (Author)

The study was conducted to obtain information on test-retest differences in Articulation Indices (AI) when a clinical threshold-based method is used to calculate AI. Standard deviations were greatest when the AI was near 50 percent and were also dependent on the relationship of the hearing thresholds and speech spectrum. (Author/DB)

The average FM advantage over a personal hearing aid was equivalent to a 15dB improvement signal-to-noise-ratio (S/N). The benefit offered by the FM system decreased as the environmental signal-to-noise-ratio increased but remained significant even at +15dB. Significant improvement was also found with directional as compared to omnidirectional…

In a test of auditory discrimination, 15 normal adults and 15 subjects with sensorineural hearing loss repeated monosyllabic words under conventional and subject-controlled methods of presentation. (Author/LS)

Forty infants, 3- to 12-months-old, participated in a study designed to differentiate the auditory response characteristics of normally developing infants in the age ranges 3 - 5 months, 6 - 8 months, and 9 - 12 months. (Author)

Examples of pattern cues that are available to profoundly hearing-impaired children are presented through an optical analog, and the usefulness of these cues is shown with regard to vowel and consonant identification, word stress-pattern perception, and distinction among sentences that differ in number of syllables, pattern, intensity, or rate.…
