By Peter Dockrill (selimaksan/iStock) If you're one of the 50 million Americans who experience the constant ringing of tinnitus - or you just live in a noisy house or apartment and find it hard to get a good night's sleep - you might be familiar with white noise generators.
The threshold of human hearing is typically around 0 dB, while normal conversation levels usually fall within a range of 50-65 dB. When it comes to white noise, setting the volume between 50 and 70 dB is recommended for most users. The ideal dB level for white noise will vary depending on individual preferences and reactions to different volumes.
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 refers to a noise that contains all frequencies across the spectrum of audible sound in equal measure. Because white noise spans multiple bands of sound, it is sometimes referred to as broadband noise.
White noise is us hearing all frequencies at the same time. And the same goes for pink noise, brown noise, and all other colored noises too. It also applies to sound masking, a specially engineered noise used to even out the soundscape of uncomfortably quiet offices and improve the acoustic privacy of employees.
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. . 274 92 439 178 421 123 495 228
