Some listeners find white noise to be harsh or tinny. One popular alternative is pink noise, which also includes noise from the entire spectrum but emphasizes specific, lower frequencies to create a deeper, gentler sound. Some users compare pink noise to rushing water, heavy rain or strong wind through leaves. This subdued, fuller sound offers many of the same benefits as white noise, such as eliminating background sounds, but it’s more relaxing for many listeners. It’s been found in heart beat rhythms, neural activity, and even DNA sequences. If this is noise found in your mind and body, then maybe it’s just what the doctor ordered. Common benefits of pink noise include: Improved focus, Alleviated headaches, Soothed babies and young children, Better sleep.
