White noise<\/h3>\n\n\n\n<p>Let\u2019s start with the most straightforward, and probably the most well-known: white noise. White noise consists of an equal amount of every frequency, all played at once. It happens in real life when your TV or radio makes static noise.<\/p>\n\n\n\n<p>However, because of our ears\u2019 frequency response, we perceive higher frequencies as louder, so it doesn\u2019t sound particularly balanced to most people. Pretty much any other color is basically a slight variation on white noise, based on a rough comparison between the frequency spectrum and the color spectrum. The most obvious and least helpful to know about, black noise, is simply silence.<\/p>\n\n\n\n<p>Here&#8217;s what white noise sounds like:<\/p>\n\n\n\n<figure class=\"wp-block-audio alignwide\"><audio controls src=\"https:\/\/splice.com\/blog\/wp-content\/uploads\/2020\/09\/White_noise.ogg\" preload=\"auto\"><\/audio><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"Pink\">2. Pink noise<\/h3>\n\n\n\n<p>Pink noise is essentially bass-boosted white noise, where the amplitude decreases as the frequencies get higher. It got its name thanks to the pink \/ violet hues present at the lowest frequencies of light. This is the perceptually &#8216;balanced&#8217; white noise that many of us are comfortable with; a lot of &#8216;white noise machines&#8217; actually play something that&#8217;s a lot closer to pink noise.<\/p>\n\n\n\n<p>Pink noise sounds similar to the rumble of a thunderstorm, and <a aria-label=\"it\u2019s been proven to help people sleep. (opens in a new tab)\" href=\"https:\/\/www.theatlantic.com\/health\/archive\/2013\/04\/study-listening-to-certain-sounds-seems-to-improve-sleep\/274921\/\" target=\"_blank\" rel=\"noreferrer noopener\">it\u2019s been proven to help people sleep.<\/a> It\u2019s based on a mathematical curve that can be found everywhere, from DNA to the stock market to traffic jams\u2014but we won\u2019t get into that right now.<\/p>\n\n\n\n<p>Here&#8217;s what pink noise sounds like:<\/p>\n\n\n\n<figure class=\"wp-block-audio alignwide\"><audio controls src=\"https:\/\/splice.com\/blog\/wp-content\/uploads\/2020\/09\/Pink_noise.ogg\" preload=\"auto\"><\/audio><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"Brown\">3. Brown noise<\/h3>\n\n\n\n<p>Brown noise is the only color we\u2019ll be discussing with a name that doesn\u2019t come from the color spectrum (although some people do call it red noise for that reason). Its namesake is Brownian motion, the term that physicists use to describe the way that particles move randomly through liquids.<\/p>\n\n\n\n<p>Brown noise is even bassier than pink noise; while pink noise boosts bass to adjust for human ears, brown noise boosts bass a bit more, just to further warm things up. This noise is similar to the sound of waves crashing or winds roaring, so if you\u2019re a fan of the sea, brown noise might be the noise for you!<\/p>\n\n\n\n<p>Here&#8217;s what brown noise sounds like:<\/p>\n\n\n\n<figure class=\"wp-block-audio alignwide\"><audio controls src=\"https:\/\/splice.com\/blog\/wp-content\/uploads\/2020\/09\/Brown_noise.ogg\" preload=\"auto\"><\/audio><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"LessCommon\">Noise colors that are less common<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"Blue\">1. Blue noise<\/h3>\n\n\n\n<p>Blue noise is, unsurprisingly, the opposite of pink noise. Rather than being bass-boosted, it\u2019s treble-boosted, and the sound frequencies are so high that most of them are barely even perceptible to us. It sounds pretty similar to the hiss that occurs when you stick your thumb in a hose with running water\u2014a high, screechy tone.<\/p>\n\n\n\n<p>In a similar vein, some people also use violet noise, which has even louder high frequencies than blue noise (violet is to blue as brown is to pink). These aren\u2019t particularly useful for helping you improve your sleep, but they have an important application in <a aria-label=\"audio dithering. (opens in a new tab)\" href=\"https:\/\/splice.com\/blog\/what-is-dithering-audio\/\" target=\"_blank\" rel=\"noopener noreferrer\">audio dithering.<\/a><\/p>\n\n\n\n<p>Here&#8217;s what blue noise sounds like:<\/p>\n\n\n\n<figure class=\"wp-block-audio alignwide\"><audio controls src=\"https:\/\/splice.com\/blog\/wp-content\/uploads\/2020\/09\/Blue_noise.ogg\" preload=\"auto\"><\/audio><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"Gray\">2. Gray noise<\/h3>\n\n\n\n<p>Gray noise is very similar to pink noise, but with one key difference. While pink noise approximates a curve to adjust for all human ears, gray noise is tailored specifically by scientists for each person who uses it.<\/p>\n\n\n\n<p>We all share pink noise, but my gray noise isn&#8217;t your gray noise. Gray noise follows a much less general curve, with more specific dips and jumps at certain frequencies to accommodate one\u2019s unique frequency response. It\u2019s used to treat hearing problems like tinnitus and hyperacusis, and doesn\u2019t have many popular use cases outside of medicine.<\/p>\n\n\n\n<p>Here&#8217;s one example of gray noise:<\/p>\n\n\n\n<figure class=\"wp-block-audio alignwide\"><audio controls src=\"https:\/\/splice.com\/blog\/wp-content\/uploads\/2020\/09\/Gray_noise.ogg\" preload=\"auto\"><\/audio><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"Differences\">The difference between noise colors<\/h2>\n\n\n\n<p>Let&#8217;s close off by recapping the difference between some colors of noise that are commonly confused.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"BrownVsWhite\">Brown noise vs. white noise<\/h3>\n\n\n\n<p>Brown noise is significantly bassier than white noise, which features an equal amount of every frequency.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"PinkVsWhite\">Pink noise vs. white noise<\/h3>\n\n\n\n<p>Pink noise is bassier than white noise, which features an equal amount of every frequency.
