Exploring the spectrum of noise colours – Beyond white noise, there is a palette of “colors” of noise, each with its own characteristics and potential uses. Red noise (or Brown noise): Characterized by higher energy at lower frequencies, it resembles the sound of a strong wind or a thunderous waterfall. Its power decreases as the frequency increases, making it soothing for some listeners. Pink noise: Pink noise is a mix of white and red noise. It has equal energy in every octave and is often found in nature, like the rustle of leaves or rain. Pink noise can enhance sleep and memory consolidation.Blue noise: With more energy at higher frequencies, blue noise is the counterpart to blue light, sounding hissy and sharp. Audio production teams sometimes use it to mask lower-frequency noises.
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 even more information on https://www.hi-fid.com/.
