Feel the Music
We've all heard of smart phones, but how about smart clothing? The CuteCircuit company has stepped up the technology beat and invented the SoundShirt, which was designed specifically for people who are deaf or hard of hearing. How does this incredible shirt work?
First, let's talk about a little science. People who have either all or some hearing loss don't actually listen to music the way that hearing people do, but they can feel it. Sound is made up ofvibrations, called sound waves, which hearing people can hear through their ears with the help of the brain. What's really cool is that deaf people sense vibrations in the part of the brain that others use for hearing!
So how is this remarkable technology able to function? First, CuteCircuit had to figure out a way to send signals to the body, kind of like how you can feel when your phone vibrates in silent mode. Those connections the body can feel are calledhaptics, a use of technology that simulates the senses of touch and motion. The SoundShirt has tiny sensors woven into the shirt to pick up sound and transfer signals to the brain and body.
To test this music-to-shirt-to-wearer's brain connection, CuteCircuit set microphones around the stage of a symphony orchestra. The shirt's computer system digitally received the sounds coming from the instruments. Then the sensors, working like little motors, changed the signals into vibrations and the shirt wearer's brain did the rest.
The SoundShirt lets people who are deaf or hard of hearing enjoy music in a unique way. The very deep musical sound, or pitch, of instruments like drums and basses vibrates in the lower part of the shirt. Higher pitched sounds from instruments like the flute or violin vibrate higher, around the neck and arms. As the music plays, the sensations combine while the brain gets to work putting together all the different vibrations, allowing the wearer to "hear" the concert.
You might think this innovation would look like something out of a science fiction movie, but in fact, these shirts are wireless! And the decorative laser-lined design on the shirt looks like an image of sound waves.
Technology's purpose is to help people and make life better. Think of all the amazing things designers, engineers, and producers of wearable tech will be able to do for humankind.
