What is Black Noise?

Black noise is a unique type of noise characterized by its near or total silence, with occasional spikes of sound.

What Makes Black Noise Different?

Unlike other types of noise, such as white, pink, or brown noise, it doesn't involve consistent sound frequencies. Black noise has minimal sound activity or none at all.

It may include brief, infrequent sounds, like natural ambient noises, and is often compared to a “void” or “sound vacuum.”

This type of noise isn’t commonly used in therapy or audio engineering, but its concept resonates with those seeking environments of quiet or stillness, sometimes with sparse natural sounds.

Black noise is appealing for creating calming environments where minimal sound interruptions are desired, making it useful for those who find even subtle background noise disruptive to relaxation or sleep​.
