sonic alert
Sonic Alert is an American company from Troy, Michigan, founded in 1978 by Adam Kollin. He originally developed signalling devices for his deaf grandmother — today Sonic Alert is present in over 40 countries. The flagship product is the legendary Sonic Bomb alarm clock: with up to 113 dB (as loud as a chainsaw), pulsating strobe lights and the Super Shaker bed vibrator, it wakes even the deepest sleepers. Originally designed for the hearing impaired, the Sonic Bomb has become a cult classic among heavy sleepers worldwide.
