Why Loud Alarm Clocks?
Loud alarm clocks are an affordable way for parents to help their children wake-up. While children grow through their teenage years their sleep patterns change and they begin to sleep later throughout the night, resulting in their deepest sleep being later into the day. College students are not immune to this either. Many exams have been missed due to oversleeping. Children can be in such a deep sleep when the alarm goes off, that they often wont hear the constant beeping of an alarm clock. Loud alarm clocks from Sonic Alert offer a solution with volumes reaching 113dB. Wow, those are loud alarm clocks, yet there is more to this than simply volume. Some children hear certain tones over other ones. With the tone control option on these loud alarm clocks you will be able to fine tune the tone in conjunction with the adjustable volume that will penetrate that part of the brain that is canceling out the alarm. The chart below provides a visual aid for comparing everyday sound levels.
