Think of white grapefruit, pink grapefruit, and oranges. Indeed, white noise, pink noise, and sound masking are all fundamentally broadband noises, but that’s pretty much all they really have in common. It does sound a bit like a broken TV, doesn't it? White Noise, Pink Noise, and Sound Masking Are Different Kinds of Broadband Noises

That’s right, to most people, white noise sounds just like a broken TV set.Įnjoy this 1 minute of pure white noise.
Meanwhile, the best approximation to white noise remains the static sound you hear between radio stations on the FM band, or the “snow” you get on a television with no signal.
In fact, many familiar sounds resemble white and pink noise, such as the sound of heavy rain, waterfalls, wind, ventilation systems – even the sound of a big crowd cheering in a stadium. So whether you’re talking about white noise, pink noise, brown noise, or sound masking, they can all be referred to as broadband noises, noises whose energy is distributed across the entire audible range of frequencies – simply put, random, continuous noises that are simultaneously low, mid and high-pitched, but in varying proportions depending on the noise color or type you’re dealing with. 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. White noise is us hearing all frequencies at the same time.Īnd the same goes for pink noise, brown noise, and all other colored noises too. White light is us seeing all colors at the same time. Why is it called White Noise anyway? You may have already learnt that White Light is the combination of all the different colors in the color spectrum, right? Similarly, white noise is a combination of all of the different frequencies of sound – such as all of the imaginable tones that a human can hear, played together at the same time. And while referring to how such special sounds do a great job at drowning out undesirable sensory stimuli, it’s easy to assume that all colored noises, white/pink/brown noise generators, sound machines, and sound masking systems are one and the same. In fact, many people use the terms white noise, pink noise, and sound masking interchangeably. Have you been searching for ways to improve speech privacy and reduce noisy distractions in your office space? Then you may even already know about sound masking. And if you got ever so slightly curious about white noise, then you’ve likely heard of pink noise too. You may even have already read about how it can help you sleep, think, and concentrate better, by hiding unwanted sounds around you. There’s a fair chance you’ve heard of white noise before.
