Frequently Asked Questions
How can ambient sound improve my sleep routine?
Ambient noise in general is known for its soothing, relaxing properties—hence its presence in the form of audio-led meditation apps, sound baths, and spa music, to name a few—but, according to the Sleep Foundation, white noise is popular for its combination of all sound frequencies at equal measure. This frequency combination creates a sound similar to a static TV or untuned radio. According to a 2017 study in Frontiers in Neurology, healthy subjects exposed to broadband sounds like white noise enjoyed a 38% reduction in sleep onset latency, or the time it took them to fall asleep. A sub-study also monitored subjects who reported trouble sleeping at home; in those cases, patients reported a subjective increase in sleep quality. The results are in: White or ambient noise can help you sleep.
What’s the difference between white, brown, and pink noise?
“Colored” noise is a form of sound therapy that classifies the sound spectrum and contains low frequencies at various volume levels. “The balance of how much energy they have and what the frequency range is is really what changes between those descriptors of pink versus brown versus white,” explains Barbara Shinn-Cunningham, Ph.D., a Cowan professor of auditory neuroscience and director at Neuroscience Institute at Carnegie Mellon University. “The differences might have real perceptual consequences but they all have this quality of being kind of boring to the brain and capable of blocking out other sounds.”
