Pros. The pros of using white noise for babies is that it soothes them and can help them get the sleep they need. One study of newborns found that 80 percent exposed to white noise dozed off within five minutes, while only 25 percent of those without the background noise fell asleep as quickly. [2]It's recommended that white noise volume for infants and young children should not exceed 50 decibels. In conclusion, the optimal decibel level for white noise depends on personal preferences, ambient noises, and the listener's sensitivity. With the development of urbanization, road traffic noise has become the main source of urban noise pollution, accounting for 60-80% [].Noise exceeding 50 dB affects sleep and rest, noise exceeding 70 dB triggers psychological stress and distraction, and living for a long time in a noise environment of more than 90 dB can seriously damage hearing and induce other health problems [].
White noise can help to calm racing thoughts. Blocks loud noises. The constant "shhh" sound of white noise helps to block environmental noises that may prevent sleep, such as cars, neighbors, and sirens. Easy to use. Sleep apps like BetterSleep make it easy to have white noise at your fingertips, even when you travel.
Noise above 70 decibels can cause hearing damage when listened to for an extended period. Keep your white, pink, or brown noise well below 45 decibels. If this needs to be adjusted for different noise conditions, avoid exceeding 70 decibels (dB), particularly for an extended period.Dangers of White Noise. The long-term safety of white noise is subject to debate. The American Tinnitus Association, for instance, states that noise exposure below 80 to 85 decibels is likely safe. Other experts say that white noise may harm the brain and central auditory system over time. Different organizations suggest different volume levels for white noise depending on usage context. For example, the American Academy of Pediatrics (AAP) recommends a general maximum white noise volume of 50 A-weighted decibels (dBA), while the World Health Organization (WHO) suggests an even lower limit of 30 dBA for hospital nurseries. .
