White Noise Machines Can Cause Infant Hearing Loss

Parents of infants are often willing to do anything to get their child to sleep. There are hundreds of "sleep training" books and methods, soothing lotions with lavender, and swaddle blankets that all claim to help a baby sleep.

Another thing that is often recommended is an white noise machine. These machines are supposed to provide soothing sounds to help babies get to sleep faster and sleep longer even if the rest of the house is not totally quiet.

But a new study has found that those white noise machines that are supposed to help babies may be hurting them.

Infant sleep machines are designed to produce white noise to create an environment better designed for sleep by eliminating acoustic interruptions. Many parenting experts recommend the use of sleep machines to help infants fall asleep, as well as to mask the environmental sounds that could disturb an infant during their sleep cycle with the machine's louder, more consistent sounds.

Getting a good night's sleep is important for infants (and their parents) but not at the risk of hearing loss.

Researchers at the University of Toronto and The Hospital for Sick Children in Toronto, Ontario, Canada found that the volume of these sleep machines can actually be damaging to a baby's hearing. The sound levels according to their research may be set too high for infants.

This study was published in the January 2014 issue of Pediatrics, the official journal of the American Academy of Pediatrics.

The researchers working on this study examined 14 commercially available infant white noise sleep machines played at maximum volume. They measured the audio output of the machines at a variety of distances to simulate the distance there would likely be between the machine and the baby.

This may be surprising to many parents, but the researchers found that if the machines are attached to the crib or placed next the the crib on a table, all 14 machines would exceed the recommended sound levels for hospital nurseries. Three of them would even exceed occupational sound limits for adults!

Scary to hear this as we used a white noise machine many times to get our child to sleep. The good news is it was never near her bed but on the other side of the room.
