In modern life, improving sleep quality has become a significant concern for many people. As an effective sleep aid, white noise is gaining popularity. But what exactly is white noise? How does it help us sleep? This article will explain the principles of white noise and its practical applications in sleep aid, providing scientific evidence to help you better understand this fascinating sound therapy. White noise is a random signal with equal intensity at different frequencies, giving it a constant power spectral density. In simple terms, white noise contains all frequencies of sound, with equal energy at each frequency. This makes white noise sound like a continuous “hissing” noise, similar to the sound of a fan, rain, or ocean waves. Discover extra information at https://www.hi-fid.com/.

Different brainwaves indicate different levels of consciousness, like deep sleep or strong focus. For example, an alert, focused state of mind is indicated by beta waves, while relaxed wakefulness is linked to alpha waves. EEG (electroencephalography) allows us to measure these brainwave frequencies and observe how they change with different mental states — from calm and creative to highly concentrated. Now, with newer technology like fNIRS (functional near-infrared spectroscopy), we can also measure brain oxygenation — a key indicator of cognitive workload and mental effort. EEG and fNIRS combined, like in our newest device, Muse S Athena, gives us an even deeper understanding of how focused or overloaded the brain may be. White noise can help the brain stay focused by covering up distracting sounds that could shift its attention. It acts as a buffer, promoting a steady state of focus-driven brain activity. Because of this buffer, white noise can help you fall asleep faster and stay asleep longer.

Violet noise: Similar to blue noise but with even more emphasis on the higher frequencies, violet noise is often used in electronic devices to mask tinnitus. It can also serve as a tool for sound equalization. Gray noise: Sounds “even” across frequencies to the human ear, similar to white noise, but with a psychoacoustic correction to make it sound flat. Audio equipment testing often uses gray noise. Green noise: Often described as the background noise of a stream of steady ocean waves. It’s a mid-frequency version of white noise and can be soothing. Orange noise: Using all frequencies except those our ears consider in tune, orange noise sounds like the chatter in a crowded room or the bustle of a busy cafe. This noise can be stimulating and helpful to creative projects.
