The Radioear B70A and Siemens Fonator electromechanical vibrators were coupled separately to the fingertip of 72 normal young adults. Tactual thresholds were obtained with (a) pure tones in octave and half-octave intervals from 125 through 1,000 Hertz and (b) phonemes comprising the Ling Five Sound Speech Test. / Threshold measurements served as a sensation level reference for tactual stimuli used in a subsequent visual-tactual communication task. Subjects used a television monitor to observe a videotaped speaker uttering sentences from the CID Everyday Sentences Lists. The tape soundtrack drove a respective vibrator at predetermined suprathreshold levels. Subjects failed to demonstrate statistically significant differences in speechreading performance as a function of systematic changes in the intensity of tactual stimuli with either electromechanical vibrator. Statistically significant differences were observed as a function of speechreading the same sentences twice. / Source: Dissertation Abstracts International, Volume: 43-09, Section: B, page: 2866. / Thesis (Ph.D.)--The Florida State University, 1982.
