How is the alarm in the Lifetone HL Bedside Fire Alarm and Clock different from the alarm in my smoke alarm?
The Lifetone HL Bedside Fire Alarm and Clock has a 520 Hz square-wave sound pattern alarm that utilizes low and multiple frequencies which are heard better by the hearing impaired. In contrast, the vast majority of smoke alarms generate alarms above 3000Hz, a very high pitched tone. Research shows that for most people with hearing loss, the ability to hear sounds above 2000Hz is greatly diminished. This is especially true for people with age-related hearing loss, a condition called presbycusis. Independent testing has proven that the 520 Hz square-wave sound pattern is more effective than traditional audio or strobe smoke alarms in waking seniors, children and those experiencing mild to moderately severe hearing loss.
