Daniel Belquer, the "Chief Vibrational Officer" of Music: Not Impossible, developed a haptic suit with vibrating plates to enhance the live music experience for deaf and hard-of-hearing individuals. The suit, showcased at an event called "Silent Disco: An Evening of Access Magic" at Lincoln Center, provided unique textures and sensations corresponding to the music, creating an inclusive environment for all attendees, regardless of hearing ability. NPR reports: His team started by strapping vibrating cell phone motors to bodies, but that didn't quite work. The vibrations were all the same. Eventually, they worked with engineers at the electronic components company Avnet to develop a light haptic suit with a total of 24 actuators, or vibrating plates. There's 20 of them studded on a vest that fits tightly around the body like a hiking backpack, plus an actuator that straps onto each wrist and ankle. When you wear the suit, it's surprising how much texture the sensations have. It can feel like raindrops on your shoulders, a tickle across the ribs, a thump against the lower back. It doesn't replicate the music -- it's not as simple as regular taps to the beat. It plays waves of sensation on your skin in a way that's complementary to the music.
So as someone who is both hard of hearing and an engineer I should point out that that’s not a new way for us to enjoy music. Maybe it enhances it, but Deaf people are known to love music that hits the chest cavity just right.
