What does white noise do? White noise is a steady, consistent sound created by blending all the audible frequencies the human ear can detect — typically ranging from 20 to 20,000 hertz. Think of it like the background hum at a busy cafe, where every voice, espresso machine and blender somehow merge into a single, soothing buzz. That layered effect is what gives white noise its unique ability to mask distractions and calm the brain. So, why “white” in white noise? The term white noise comes from white light, composed of all the colors or frequencies of light combined. Similarly, white noise is a blend of all audible frequencies. This blend creates a constant, soothing sound that can mask other disrupting sounds impacting our brain focus and mental health.

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. Read extra information on hi-fid.com.
