“I’m not saying they were (producing hazardous sound), but they were capable. “The main message is that off-the-rack machines - three of them - at certain conditions are capable of producing hazardous levels of sounds,” Papsin said. And all but one of the machines were capable of producing sounds greater than 50 dBA from across the room. All machines were capable of producing sounds greater than 50 dBA when placed either in or next to the crib. The app was created to empower people to test noise levels in their workplace, make informed decisions about noise exposure, and prevent occupational hearing loss. Three machines were capable of producing noise in excess of 85 dBA when positioned on the side of the crib. The free app combines the best features of professional sound levels meters and noise dosimeters into one simple tool. The measurements were also adjusted to estimate what a six-month-old child would hear. In recent years, a growing number of parents have been using sleep sound machines to produce white noise designed to soothe babies to sleep however. The microphones for the sound meters were fixed with special attachments to simulate ear canals. Using a sound booth, the researchers tested each device turned to its maximum volume and placed sound meters at varying distances to simulate the machine hanging on the side of a crib, being placed next to a crib and being across the room. When they’re played at a high volume, for a long period of time, the baby is exposed to noise which their developing ears are not designed for. Listening to music at very high volume through headphones can contribute to hearing loss and tinnitus. The Canadian study, published in the journal Pediatrics, measured. In recent years, some doctors have expressed concern about using white noise to help babies sleep. White noise machines can increase the risk of noise-related hearing loss as they work on the principle of accumulated noise. The machines produced a total of 65 different sounds that included white noise and nature, mechanical and heartbeat sounds. Putting your baby to sleep next to a white noise machine may increase the child’s risk of hearing loss, a new study suggests.
