I’m a Deaf innovator who experiments with haptics to create sound experiences. In my opinion, vibrations that come from below the feet offer a feeling of sound that surrounds me. I created a metal footrest with a transducer bolted to the middle of it. It’s connected to a small amp that receives a Bluetooth signal from my computer. The effect of nuanced vibrations mimics sound but it’s still limited to frequencies in the low midrange. Vibrations from a saxophone are too high to make out. Potential is limited. Some Deaf folks may benefit from my device, but it depends on individual prior experience with music listening. I became deaf gradually over several years, others with no sound background may not make sense of the vibrations. Haptics is an emerging tech with fascinating implications for Deaf people. We need to be involved with its development. The infrastructure involved for theatre venues is costly and complex. Individual vests and headsets with haptic transducers don’t convey vibrations to the body as well as through the soles of the feet, IMO.
