3-Layered Deep White Noise | 9 Hours Black Screen | Noise Masking | Boost Dopamine & Focus

Three types of white noise combine to make a deeply nuanced noise-masking sound. With 9 hours of plain black screen, It's ideal for any time you need to focus or ignore intrusive environmental sounds. White noise is also thought to boost dopamine production which may help to improve mood and ease the challenges presented by ADHD.

White Noise: White noise is a type of random signal that contains equal energy across all frequencies in the audible spectrum. It is named "white" because it is analogous to white light, which contains all colors of light combined. In white noise, the amplitude of each frequency component is independent and has an equal contribution, resulting in a flat frequency spectrum. This means that every frequency has an equal chance of occurrence, making white noise sound like a hiss or static.
