Tactile-audio desynchrony is as critical as audiovisual desynchrony

Evidence

The JND of detection of haptic–audio asynchronicity has been found to be 24 ms with impulsive stimuli (Adelstein et al., 2003), which is a value similar to that obtained with tests on the detection of audio–visual asynchronicity. However, in many cases, the auditory–visual asynchronicity threshold values are higher than auditory–tactile asynchronicity threshold values. Therefore, auditory–tactile asynchronicity may be even more critical than auditory–visual asynchronicity. In particular, musicians have lower auditory–tactile asynchronicity thresholds, about 10 ms, than the general population, possibly because of their training. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1827

• QUESTION: Why do musicians have lower haptic-audio thresholds — is it training or a general precision of temporal integration? Worth chasing.
