SimplyNoise is exactly what it says: it’s simply noise—white, pink, or brown.
Now, a few years ago, I would have wondered, “Why would anyone want noise?” But now that I’m older, wiser, and desperate for a quite place, I’m aware of the power that white noise can offer.
Many people find that noise, as opposed to music or spoken word, helps them to focus and drown out external noises and distractions. I’m not a huge fan of using noise to create a “cocoon of sound,” but I can see how it might help some people.
