A smoke alarm was invented for the deaf

There are special smoke alarms invented specifically for people with profound hearing loss. Instead of emitting a high-pitched alarm, the fire alarm rapidly flicks a strobe light on and off. Vibration notifications placed in pillows and beds work in unison with the smoke alarm to alert deaf people to the danger to their house and themselves. When the alarm goes off, the vibration devices in the pillows and bed activate, shaking the person awake and warning them of the imminent threat of fire.
