New Instrumentation for Research on Vibrotactile Sensitivity of the Tongue

Abstract

The nee~ fo~ a r~1iable instrument for vibrotactiJe stimulation of the tongue is presented. A signal delivery and s~gn:u monltormg mstrume?tation .system as well as .an appropriate method and apparatus for holding and positlonmg the test structure IS descnbed. The system IS capable of controlling those spatial and psychophysical parameters affecting vibratory study of the tongue.

Oral vibrotactile stimulation: A method for monitoring change in lingual sensitivity as a function of time

“…These thresholds were ob tained to monitor changes in lingual tactile sensitivity that might be occurring during the 7 -week period. Equipment and procedures employed for testing are described in detail by Fucci and Kelly (1972). Weekly thresholds were obtained at the frequencies of 125, 250, 300, and 500 Hz.…”

Modification of instrumentation for research on lingual vibrotactile sensitivity: Elimination of the tongue clamping procedure

“…2 The original tube systems have been replaced by solid state circuitry, but the arrangement has not been altered. 2 The original tube systems have been replaced by solid state circuitry, but the arrangement has not been altered.…”

Interaction between Auditory and Oral Sensory Feedback in Speech Regulation

“…A white noise generator was used to provide auditory masking. Equipment and procedures used in obtaining lingual vibrotactile thresholds have previously been described in detail by Fucci and Kelly (1972).…”
