A noise level chart showing examples of sounds with dB levels ranging from 0 to 180 decibels. As a frame of reference, here are the decibel levels of sounds you may encounter in your everyday life. 0-30 dB, Very Faint. One-sixteenth as loud as 70 dB. Very Quiet. 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. 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 []. So, does white noise help you sleep? It can do, but it's important to be aware of how loud you're listening to it! How loud should white noise be, then? Ensure you're listening at levels no higher than 50 decibels, which is roughly equivalent to the level of a quiet refrigerator humming or a quiet conversation. Another reason why white noise promotes sleep lies in the nature of our brain: it thrives on stimulation. Nightly noises tend to activate our brain, disrupting our rest. A consistent white noise serves as a satisfying stimulus, preventing overexcitement when sudden sounds occur at night. 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. D3g77.
