70 million* Americans have high-frequency hearing loss. Are you one of them?
High-frequency hearing loss inhibits you from hearing everyday sounds, from consonants such as “S” or “F” to children’s or women’s voices — even a smoke alarm. That's right a smoke alarm.
Lifetone Technology™ understands the challenges that face people with hearing loss when it comes to fire safety. The Lifetone HL™ Bedside Fire Alarm and Clock utilizes our patented sensor to hear your existing smoke alarm. In a fire emergency, it alerts and awakens you using a low and multiple-frequency 520 Hz square-wave sound pattern.
Independent studies show that 95% of hearing-impaired participants were awakened by the square-wave.
