Study: Sleep Machines May Damage Your Baby’s Hearing

(TORONTO) — Parents beware: If you use an infant sleep machine to help put your baby to sleep, you could be upping your child’s chance of developing noise-induced hearing loss.

A new study published in the journal Pediatrics says cranking the volume on those machines — which use lullabies or white noise to help block whatever’s happening in the world beyond the crib — can damage your child’s hearing.

Researchers at the University of Toronto tested 14 popular machines and found that at a distance of 30 centimeters, three of the machines were louder than 85 decibels — the workplace safety limit for adults.

Doctors recommend lowering the volume and putting the machines farther away, to ensure your babies will be able to hear you when they’re supposed to.
