Link between sound frequency and reduced wakefulness state to help you sleep better

From the opening paragraph: To cope with sleep difficulties, people use a variety of tools: white-noise machines, bedtime stories, constant phone scrolling, or letting the TV play. These sounds mask background noise, but they usually contain a wide range of frequencies rather than a targeted tone. By contrast, 42 Hz represents a precise, measurable rhythm that may align with neural oscillations involved in the transition from wakefulness to sleep. Understanding how this frequency interacts with the nervous system may help explain why some sound-based interventions feel more calming than others.
ChatGPT summary for anyone who doesn’t want to open the link:
The OP shared a paragraph from the article saying that most sleep sounds — like white noise, TV in the background, or bedtime stories — contain lots of mixed frequencies, while 42 Hz is a single, “precise” tone that might line up with brain rhythms involved in falling asleep. The piece suggests that understanding how this frequency interacts with the nervous system could explain why some sounds feel more calming.
The rest of the article expands on that idea, talking about how certain frequencies can influence brain activity and mentioning some older studies on low-frequency sound. But it doesn’t offer any solid, peer-reviewed evidence that 42 Hz specifically does anything for sleep. Most of the claims are framed in speculative language without proper citations.
So overall, it reads like an interesting idea, but the way it’s presented is a bit click-baity — it makes the concept sound more scientific and supported than it really is
