“…Perceptual studies also provide evidence for auditory-somatosensory interactions. For example, facilitative interactions between audition and touch have been observed using subjective techniques such as loudness matching ͑e.g., Schürmann et al, 2004;Gillmeister and Eimer, 2007;Yarrow et al, 2008͒ as well as objective measurements of detection and discrimination ͑e.g., Schnupp et al, 2005;Wilson et al, 2009;Yau et al, 2009;Ro et al, 2009͒. Other studies ͑Gescheider et al, 1969Gescheider, 1970͒, however, have reported inhibitory results for the detection of a tactile stimulus in the presence of a suprathreshold auditory tone.…”

Perceptual integration of vibrotactile and auditory sinusoidal tone pulses was studied in detection experiments as a function of stimulation frequency. Vibrotactile stimuli were delivered through a single channel vibrator to the left middle fingertip. Auditory stimuli were presented diotically through headphones in a background of 50 dB sound pressure level broadband noise. Detection performance for combined auditory-tactile presentations was measured using stimulus levels that yielded 63% to 77% correct unimodal performance. In Experiment 1, the vibrotactile stimulus was 250 Hz and the auditory stimulus varied between 125 and 2000 Hz. In Experiment 2, the auditory stimulus was 250 Hz and the tactile stimulus varied between 50 and 400 Hz. In Experiment 3, the auditory and tactile stimuli were always equal in frequency and ranged from 50 to 400 Hz. The highest rates of detection for the combined-modality stimulus were obtained when stimulating frequencies in the two modalities were equal or closely spaced (and within the Pacinian range). Combined-modality detection for closely spaced frequencies was generally consistent with an algebraic sum model of perceptual integration; wider-frequency spacings were generally better fit by a Pythagorean sum model. Thus, perceptual integration of auditory and tactile stimuli at near-threshold levels appears to depend both on absolute frequency and relative frequency of stimulation within each modality.

“…This basic paradigm has been adapted by others to explore, for instance, auditoryvibrotactile interactions (Yarrow et al, 2008) and auditory influences on contrast detection (Lippert et al, 2007). Jaekl and Soto-Faraco (2010), in particular, showed that audiovisual enhancement induced by multisensory integration is more effective when visual stimuli present features compatible with the magnocellular pathway.…”

Sounds Are Perceived as Louder When Accompanied by Visual Movement

In this study, we present three experiments investigating the influence of visual movement on auditory judgments.In Experiments 1 and 2, two bursts of noise were presented and participants were required to judge which was louder using a forced-choice task. One of the two bursts was accompanied by a moving disc. The other burst either was accompanied by no visual stimulus (Experiment 1) or by a static disc (Experiment 2). When the two sounds were of identical intensity participants judged the sound accompanied by the moving disc as louder. The effect was greater when auditory stimuli were of the same intensity but it was still present for mid-to-high intensities. In a third, control, experiment participants judged the pitch (and not the loudness) of a pair of tones. Here the pattern was different: there was no effect of visual motion for sounds of the same pitch, with a reversed effect for midto-high pitch differences (the effect of motion lowered the pitch). This showed no shift of response towards the interval accompanied by the moving disc. In contrast, the effect on pitch was reversed in comparison to what observed for loudness, with mid-to-high frequency sound accompanied by motion rated as lower in pitch respect to the static intervals. 2The natural tendency for moving objects to elicit sounds may lead to an automatic perceptual influence of vision over sound particularly when the latter is ambiguous. This is the first account of this novel audio-visual interaction.

“…They found that the presence of vibration tended to increase the loudness of the auditory stimulus. It should be noted, however, that based on the results of other experiments, Yarrow et al ͑2008͒ attributed the increase in loudness to a bias effect, concluding that the tactile stimulus "does not affect auditory judgments in the same manner as a real tone." Finally, Gescheider et al ͑1974͒ observed that magnitude estimates of a tactile vibratory signal were increased in the presence of a simultaneous auditory tone.…”

Perceptual interactions in the loudness of combined auditory and vibrotactile stimuli

The loudness of auditory (A), tactile (T), and auditory-tactile (A+T) stimuli was measured at supra-threshold levels. Auditory stimuli were pure tones presented binaurally through headphones; tactile stimuli were sinusoids delivered through a single-channel vibrator to the left middle fingertip. All stimuli were presented together with a broadband auditory noise. The A and T stimuli were presented at levels that were matched in loudness to that of the 200-Hz auditory tone at 25 dB sensation level. The 200-Hz auditory tone was then matched in loudness to various combinations of auditory and tactile stimuli (A+T), and purely auditory stimuli (A+A). The results indicate that the matched intensity of the 200-Hz auditory tone is less when the A+T and A+A stimuli are close together in frequency than when they are separated by an octave or more. This suggests that A+T integration may operate in a manner similar to that found in auditory critical band studies, further supporting a strong frequency relationship between the auditory and somatosensory systems.
