Effect of stimulus intensity on lingual vibrotactile fusion thresholds.
Lingual fusion thresholds for a two-pulse stimulus were obtained at a 15-dB sensation level and a 35-dB sensation level for 15 subjects (18 to 22 yr.). The 35-dB sensation level provided better temporal resolution thresholds as well as less variable responses.
