A recent article titled Infant Sleep Machines and Hazardous Sound Pressure Levels was published in Pediatrics. The study found that infant sleep machines can potentially cause hearing loss in infants. The study made the following recommendations for families
1. Place the sound machine as far away as possible from the infant and never in the crib or on a crib rail.
2. Play the sound machine at a low volume.
3. Operate the sound machine for a short duration of time.
Sounds machines can help infants sleep, just do not play them too loud or too close to the baby.
