Interactive effects between auditory and vibrotactile stimuli

This report describes a standardized training and sensory screening procedure which was used to obtain 7 separate lingual vibrotactile thresholds for each of 5 normal subjects during a 30-day interval. Baseline observations of lingual sensitivity were highly consistent and occurred within a narrow range of contractor displacements. The authors conclude that the screening method provides a quick and reliable clinical tool for general diagnostic use and discuss directions for continued research applications.

Auditory masking has become a frequently employed part of the procedure used in vibrotactile research. Research investigating the effect of auditory masking on lingual vibrotactile thresholds of sensitivity has shown that there is little difference between lingual vibrotactile thresholds under masking and no masking conditions. The purpose of the present study was to extend the investigation of the effect of auditory masking to include lingual vibrotactile suprathreshold scaling responses. 20 young adult subjects of mean age 19 yr. completed lingual vibrotactile-threshold and magnitude-estimation scaling tasks under conditions of bilateral auditory masking and no masking. Similar lingual vibrotactile-threshold values and magnitude-estimation power-function exponents for the conditions of masking and no masking were noted.
