Audio-Tactile Installations To Augment Music Perception For People With Hearing Impairment

Going out to a concert has been perceived as one of the activities people missed the most during this pandemic. However, some people's hearing impairment prevents them from enjoying this basic social event. So far, only a telecoil-loop system installed in a few theatres can provide a little auditory reinforcement. To fill that need, we investigate different systems that can provide tactile reinforcement for them. The systems vary by their complexities and the part of the body targeted. The hands are excited by metal and wood plates mounted on springs equipped with shakers. The shape of the plate is designed to elicit different resonance frequencies at different locations. The belly is excited by a large wood multifaceted structure that can be hugged. Each face is equipped with small shakers tuned to specific resonance frequencies. Finally, the audience is seated in a wood chair equipped with dowels that will directly stimulate the audience's back and legs through the chairs. The installations are displayed in museums and festivals, where the audience is invited to experience music through vibration. After that, the audience filled out a questionnaire to assess the success of each device.
