The Westclox banshee super loud alarm clock, model number 47547 is just what it is named. This super loud LCD alarm clock rings at 90 decibels, which is probably loud enough for most of the hard-to-wake folks out there! This clock is also a good option for those who are hard of hearing, and for those who need to get up before putting their hearing aids back on. All in all, it's a great alarm clock for a great price!
