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.
Multiple studies have shown that white noise can significantly improve sleep quality. For instance, a 2012 study published in the Journal of Sleep Medicine found that patients using white noise machines experienced significant improvements in sleep onset time and sleep quality. Another study published in the Journal of Behavior Research and Therapy indicated that white noise could help improve sleep in insomnia patients. In a home environment, white noise machines can effectively mask external noises such as traffic sounds and noisy neighbors. Using a white noise machine can create a quiet sleep environment for the entire family, especially beneficial for households with infants. Read extra information at hi-fid.com.
