Some more expensive generators rely on the Gaussian distribution, as it represents a better approximation of many real-world random processes. Both generators will sound the same though, and will exhibit the same flat spectrum. They will only differ by the distribution of their sample levels. Listen to our two examples: both noises play at same loudness; however the Gaussian version peaks at a higher level (0 dBFS v/s -6 dBFS). This can be explained as follows: compared to the uniform distribution whose sample amplitudes are equally distributed between a minimum and a maximum value, the Gaussian distribution produces a higher density of low level samples. To keep the loudness constant, Gaussian noise must then produce higher peak amplitudes. In other words, high level samples are less frequent in Gaussian noise than uniform noise, but much higher in amplitude. White noise has been named by analogy to light, which turns white when all frequencies are summed up into a single beam. As light changes its color when altering its frequency distribution, noise can be 'colored' too, by shaping its frequency content. The best known colors are and. There are many different kinds of waves. Sound relates to pressure waves, only audible to us between 20 Hz (bass) and 20 thousand Hz (treble). Light relates to electromagnetic waves, only visible to us between 430 trillion Hz (red) and 750 trillion Hz (violet). ![]() There is no relationship between sound and light waves: noise colors are just a handy analogy, nothing more. Applications In audio applications, white noise is used as a reference tone to check frequency responses: play back white noise through your system and check its output with a linear spectrum (FFT) analyzer. The response should keep flat when averaged over time. If your spectrum analyzer does not operate on a constant bandwidth, but constant percentage bandwidth - such as a 1/3 octave spectrum analyzer - use instead. White noise can be used to measure the adverse effects of room modes as well, although a will be better for such a purpose. In healthcare applications, white noise is used to mask tinnitus, a buzzing, ringing, or whistling in your ear, occurring without any stimulus.
