“…Specifically, DiFranco and colleagues found that auditory cues affected the ranking of the stiffness of virtual surfaces tapped by using a force-reflecting haptic interface [DiFranco et al 1997]. Similarly, Avanzini and coworkers found that the haptic perception of stiffness experienced by a user while tapping on a virtual surface with a rigid probe was influenced by auditory stimuli created with a physically based audio model of impact [Avanzini and Crosato 2006].…”

This article investigates whether auditory feedback affects natural locomotion patterns. Individuals were provided with footstep sounds simulating different surface materials. The sounds were interactively generated using shoes with pressure sensors. Results showed that subjects' walking speed changed as a function of the type of simulated ground material. This effect may arise due to the presence of conflicting information between the auditory and foot-haptic modality, or because of an adjustment of locomotion to the physical properties evoked by the sounds simulating the ground materials. The results reported in this study suggest that auditory feedback may be more important in the regulation of walking in natural environments than has been acknowledged. Furthermore, auditory feedback could be used to develop novel approaches to the design of therapeutic and rehabilitation procedures for locomotion.

“…It is generally believed that touch-produced sound sources are closely related to the haptic perception. Recently, Avanzini et al investigated the relative contributions of haptic and auditory information on bimodal judgments of contact stiffness by performing psychophysical experiments [2].…”

Research on the intermodality relationship of auditory and tactile perceptions was conducted. An experiment is performed with 78(26 auditory cues × 3 tactile cues) stimuli combinations. The result of this experiment showed that the sound intensity level definitely affects perceived sensation in three ways: 1) The perceived roughness and ruggedness sensation is more innervated when the specific frequency is enhanced, e.g. approximately 30Hz~300Hz for ruggedness and 30Hz~600Hz for roughness sensation; 2) Conversely, the perceived density is reciprocally affected by an intensity adjustment of the sound; 3) A frequency adjustment of the sound can elicit a perceived roughness if even no stimuli are conveyed to subjects. In general, the importance of congruency between modalities was observed.

“…Most of these studies focused on timing and motor performance [4][5], rather than on how the produced sound is perceived by the player. Other studies found that touch was affected by audition [6][7][8], although not necessarily in a musical context. Very few studies investigated the effect of touch on auditory perception, despite the fact that the haptic feedback provided by the instrument is always present when playing an instrument.…”

Abstract.A great variety of interactions between senses, and between motor production and senses, have been reported in previous research. In the present study, we tested whether the mechanics of a plucked string affected how the sound it produced was perceived. To test this hypothesis, we simulated the feel of a plucked string using a high fidelity haptic force-feedback device and simultaneously simulated its acoustic emission. This way, we could independently manipulate the two sensory inputs -how it felt and how it sounded -together with physical correct haptic interaction and with accurate synchronization. This arrangement makes it very plausible that the two sensory inputs came from a common source. We used a two-interval forced-choice discrimination procedure to determine the point of subjective equality of the loudness between a stiff and a soft plucked string. When the stiffness of the string was low, the sound was perceived to be softer. Interestingly, this effect was found only when the first string was less stiff than the second string plucked during a comparison. The results are consistent with the inverse effectiveness principle of multisensory integration.
