Possibly. The evidence is mixed, emerging or strongly context-dependent.

White noise is theorized to help infant sleep partly by approximating the continuous whooshing sounds of blood flow and other noise present in utero, and by masking sudden household sounds that could otherwise trigger a startle (Moro) reflex.
White noise for babies is a steady, unchanging sound — a fan, static, or a dedicated white-noise machine or app — played in a nursery or near a crib during sleep.
The practice is often traced to the idea that constant sound mimics the whooshing environment of the womb, and to pediatric sleep consultants who recommend it to mask household noise. It's become a default recommendation in mainstream baby-sleep-training advice and a whole product category of dedicated devices.

Relevant mechanisms: circadian timing, sleep pressure, arousal, breathing, light exposure, temperature, learned cues and expectation.
A ritual may be useful without receiving an honorary degree in endocrinology.
People often start a new intervention when a symptom is unusually bad. Many fluctuating symptoms naturally move back toward their usual level. If a new product was started at the low point, ordinary improvement can look like a treatment effect — the timeline is simply flattering the newest object in the bathroom.
Once someone has invested money, attention and hope, the mind naturally notices confirming evidence. Good day after starting: it worked. Bad day: probably needs another week. No change: maybe the dose is wrong. This is why predefined outcomes and stop rules matter — they protect the experiment from becoming a subscription.
Expectation, attention, previous experience, ritual, sensory cues and other simultaneous behaviour changes can all influence subjective outcomes such as pain, sleep quality, stress, energy and mood. Subjective improvement alone can't tell us which mechanism caused it — that's what a comparison group is for.
Persistent insomnia, gasping, breathing pauses, loud habitual snoring or severe daytime sleepiness should be assessed.
If you want an honest cue for this behaviour rather than a medical claim, OrcaDream is built for exactly that job — a placebo, not a treatment.

Can this replace medical treatment? No. A wellness ritual can complement appropriate care, but it should not replace diagnosis, prescribed treatment or urgent assessment.
