When using a white noise machine at less than 120 decibels, there is minimal risk to your hearing or development of. Three of the machines were even capable of producing sound levels of 85db when placed on the crib rail. It really just depends on how you’re using your white noise machine. 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. Over time these cells die and permanent hearing loss occurs. White noise machines can increase the risk of noise-related hearing loss as they work on the principle of accumulated noise. ![]() Consistent exposure to moderate-level loud sounds damages the hair cells in the inner ear. Hearing loss occurs when the tiny hair cells in the inner ear are damaged by loud sounds. When placed at 30cm and one metre, all the devices exceeded 50dB, the recommended decibel limit for hospital nurseries. Sounds that are less than 80 decibels are unlikely to cause hearing loss. Though brown noise is deeper than white noise, they sound similar to the. This makes it deeper than pink and white noise. The first was from 30cm, to simulate the device placed on a crib rail, the second distance was at one metre, simulating placement near a crib and finally from two metres, simulating placement across the room. Brown noise, also called red noise, has higher energy at lower frequencies. The sounds were played at a maximum volume level at three distances to simulate different scenarios. Sounds of white noise machinesĪ Canadian research team tested 14 different white noise machines with a total of 65 sounds. For adults, the sounds produced by white noise machines aren’t dangerous, but the ears of infants are more delicate and more susceptible to sounds. ![]() White noise machines or sleeping machines used to help infants sleep can exceed noise levels for hospital nurseries and potentially damage the hearing of the sleeping infants, a Canadian study shows. Unilateral hearing loss - Single sided deafness After finding a recommendation for white noise in Happiest Baby on the Block, Naomi Tucker, 39, bought a machine so that her daughter, Chiara, 15 months, could fall asleep nightly to ocean. In recent years, some doctors have expressed concern about using white noise to help babies sleep.
