A bright, steady sound with energy spread evenly across the frequency spectrum.
Even power per hertz
White noise contains equal average power in equal-width frequency bands across the audible spectrum.
A brighter character
Higher octaves contain more individual frequencies, so white noise is usually perceived as brighter than pink or brown noise.
A familiar steady hiss
Its sound is often compared with radio static, air moving through a vent, or a continuous electronic hiss.
A consistent background
Some listeners choose white noise when they want a uniform background that reduces the contrast of intermittent surrounding sounds.
Use a comfortable device volume. Stop if listening feels uncomfortable.
