White Noise, Steady and Even

Forty minutes of white noise: every frequency at the same level, the sound of a detuned radio or a strong fan. It is the brightest of the three noises and the best at covering sudden sounds like voices, doors or traffic. Generated for Lullable, with no recording, voice or music in it, and faded in and out gently. If it feels sharp, try pink or brown noise.

Why this one works at night

Every frequency at once, at the same level, from start to finish. It does not change, so there is nothing in it for your mind to follow. The pace is flat and constant, and the whole of it is bright, clean, even. Good for masking sharp noises. There are no words to follow and no music to wait for, and it fades out on its own at the end.
