    Loud alarm brings peace

    Posted by Unknown on 20th Mar 2018

    I hear nothing under 70 decibels. Hence, my older alarm clock for the hearing impaired didn't work for me. Had to use the lamp plug-in which was a real pain.Problem solved with this purchase. No lamp plug ins required for a flashing light, and the alarm is sufficiently loud. No anxiety about not hearing/seeing the alarm, so I sleep much better. Some loud sounds do bring peace, at least peace of mind.
