Are noise machines hazardous to infants' hearing?

By Andrew M. Seaman NEW YORK (Reuters Health) - If a so-called white noise machine is kept at full volume in a room with a sleeping baby, it may be potentially hazardous to the child's hearing, suggests a new study. The study cannot say exposure to the machines' noises is actually impairing children's hearing - just that the devices may be capable of creating sounds loud enough to cause hearing loss after prolonged exposure. "Everyone knows aspirin is safe, but everyone knows you don't take 40 of them," Dr. Blake Papsin said. White noise machines, also known as sleep machines, produce sounds to soothe infants to sleep and help mask other noises, Papsin and his colleagues write in the journal Pediatrics.
