The Sonic Bomb alarm clock is a vibrating, bed-shaking alarm clock that is made specifically for heavy sleepers, the elderly, and those with hearing impairments. It claims to be the strongest alarm shaker on the market and has been around since 1980. You can set multiple alarms with a duration of 1 to 59 minutes, and it has a snooze feature that lasts anywhere from 1 to 30 minutes. 

The Sonic Bomb alarm reaches 113 dB when set off and also has a flashing light feature just in case the sound wasn’t enough to get you to wake up. It comes with typical features that you would find on a regular alarm clock like a dimmer to control the brightness, batter backup, snooze button, volume control, and a LED display. One of the best features is that you can turn off the volume function, and only use the bed shaker attachment if you don’t want to disturb your partner. You can place the bed shaker either under your mattress or your pillow and never again worry about waking up late.
