I am a light sleeper and I have thin walls, so I will not be investing in the Sonic Bomb alarm clock. It is loud, damn loud with a maximum decibel output of 113 db. That is not as loud as a jackhammer, but it is almost as loud as a car horn. Seriously, if you are exposed to it for over a minute and a half, you are potentially damaging your hearing. As if that was not annoying enough to get you out of bed, it also has a bed shake setting. If you are old, or have heart trouble, you might want to turn the volume down. If you have thin walls it would be a good idea too. Even the most tolerant of neighbors probably do not want more decibels than a helicopter can produce. This alarm clock easily makes the top ten most annoying alarm clocks.

Price: about $34
