Wearable that helps the deaf stay aware of their surroundings
People who are hearing impaired or deaf often face situations that present challenges and dangers specific to them, like not being able to hear a smoke alarm or a gunshot.
Now there is a wearable device called SoundSense that addresses this specific need. It listens for noises that might require immediate attention and alerts the user when it detects one.
The device is small, practical and cheap. It has a microphone that passes its signal to a microchip, which watches for sudden increases in volume. When it hears one, it vibrates and the LED light flashes alerting the user.
