Health Desk: 25th Oct’18: The scientists of US said adding a recording of a mother's voice to smoke alarms could save lives.
The study found the modified alarms were more effective at waking children than conventional alarms.
And they had the potential to buy vital seconds to escape a burning building.
Fire chiefs welcomed the research, but said families should not worry about the alarms currently in their homes. The research team at the Nationwide Children's Hospital in Ohio said children were "remarkably resistant" to being woken up by sounds because they have longer and deeper sleep than adults.
The study compared a traditional high-pitch smoke alarm with voice-based ones.
There were 176 children who took part, and alarms were personalised with a recording of the mother's voice instructing their child to wake up.
Only half woke up to the blaring noise of a conventional smoke alarm. But nine in 10 woke up to the voice alarms.
The experiments were performed in a sleep laboratory, and the alarms were played once the children were in the deepest phase of sleep.
The study was published in the journal Pediatrics.
