This white noise alternative might be the relaxing brain massage you’ve been looking for. The first time I heard brown noise, I was instantly lulled into a state of deep relaxation. The tones were much more velvety and lower-pitched than the better-known sound of white noise, which, to me, has always sounded staticky and impossible to sleep to, despite what many people say about its somnolent properties. Most of available studies touting the benefits of noise therapy center around white noise, but Paré said brown noise is technically one and the same — just at a different frequency. White noise encompasses sound from the complete spectrum,” she said. “Brown noise, also known as red noise, or ‘brownian noise,’ consists of only low frequency sound, giving it more bass-heavy notes.” This deeper resonance, according to Paré, can often remind people of sounds in nature, like wind rustling trees or calm ocean waves. As such, I find it can be a very grounding sound and help move the body from a ‘fight-flight-freeze’ state back into ‘rest-and-digest’ state,” she said, adding that the benefits of such a state shift can include everything from improved focus to increased sleep time and quality. Like many healing tools, Paré stressed that noise therapy really comes down to individualized care and personal preference. If you’re not yet sure how general white noise will impact your sleep, it’s a little-known fact that iPhones have a free white noise feature you can try, although its brown noise options are very limited.
