Vibrotactile Stimulation Can Affect Auditory Loudness: A Pilot Study
نویسندگان
چکیده
Very few cases have been reported where tactile stimulation affects auditory perception. In this pilot study, we asked volunteers to compare the loudness of combinations of vibrotactile and auditory stimuli. A 50-300 Hz band-limited pink noise signal was used as the stimulus in the two modalities, simultaneously heard through headphones and felt in the hands to be compared to when it was heard only. On average, the same auditory stimulus was judged to be about one dB louder when it was simultaneously heard and felt rather than when it was heard only. This condition could be interpreted as having enhanced the perception of loudness by a whole jnd.

Vibrotactile--auditory interactions are post-perceptual.
Vibrotactile stimuli can elicit compelling auditory sensations, even when sound energy levels are minimal and undetectable. It has previously been shown that subjects judge auditory tones embedded in white noise to be louder when they are accompanied by a vibrotactile stimulus of the same frequency. A first experiment replicated this result at four different levels of auditory stimulation (no t...
متن کاملAuditory fMRI correlates of loudness perception for monaural and diotic stimulation
Loudness as the perceptual correlate of sound intensity is formed by some neural processing along the auditory pathway from the cochlea to the cortex. The loudness of a sound is largely determined by its level. Still, there are several other acoustical factors like stimulus bandwidth, duration, modulations, as well as personal factors like, e.g., the individual hearing status, that may affect p...
متن کاملFollow the Tactile Metronome: Vibrotactile Stimulation for Tempo Synchronization in Music Performance
In this paper we present a pilot study evaluating the effectiveness of a tactile metronome for music performance and training. Four guitar players were asked to synchronize to a metronome click-track delivered either aurally or via a vibrotactile stimulus. We recorded their performance at different tempi (60 and 120 BPM) and compared the results across modalities. Our results indicate that a ta...
متن کاملLoudness balance between electric and acoustic stimulation.
Binaural loudness balance between electric and acoustic stimulation is obtained in auditory brainstem implant listeners who had substantial acoustic hearing in one ear. The data are well described by a linear relationship between acoustic decibels and electric microamps. Based upon this linear relationship, we propose an exponential model of loudness growth in electric stimulation. The exponent...
متن کاملSelf-Representation in Mediated Environments: The Experience of Emotions Modulated by Auditory-Vibrotactile Heartbeat
In 1890, William James hypothesized that emotions are our perception of physiological changes. Many different theories of emotion have emerged since then, but it has been demonstrated that a specifically induced physiological state can influence an individual's emotional responses to stimuli. In the present study, auditory and/or vibrotactile heartbeat stimuli were presented to participants (N ...
