Fig. 1From: A direct comparison of sound and vibration as sources of stimulation for a sensory substitution gloveSensation levels for each sensory modality as a function of the intensity steps. Note. Mean numerical estimates of sensation as a function of intensity level for vibration (in red) and sound (in blue) in the magnitude estimation task. The sixth step (black dot) was used as reference intensity and was given a value of 50 (arbitrary scale). The dashed lines represent the best fits to the dataBack to article page
