Lingual vibrotactile and auditory cross-modal matching: frequency effects.
5 subjects matched pairs of auditory and vibrotactile stimuli on intensity, making judgments of suprathreshold magnitudes. Slope values for the 100-Hz cross-modal lingual vibrotactile stimulus-standard frequency condition were steeper than those for 250- or 400-Hz conditions. Slope values became steeper at about 25- to 30-dB SL, so frequency seems an important parameter to control in such research.
