Auditory-tactile systems improve music reproduction quality and enable tactile feedback.

Evidence

There are some interesting applications designed for auditory-tactile systems. The perceived quality of music reproduction has been found to be higher when vibrations are reproduced to the listener through a chair (Merchel and Altinsoy, 2013). A haptic device may also be used to provide the user with feedback. For example, mixing desks typically have a large number of input channels, each having a fader to control the level of the associated instrument. If the sound of the instrument is used to vibrate the faders, the audio engineer can recognize the instrument in each channel simply by touching the fader. This enables heads-up mixing, or mixing in low-light conditions (Merchel et al., 2010). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1828
