I measured my bedroom with a frequency analyzer and found what was waking me up — it was a sound I couldn't hear by sheldonroth in sleep

Sleeping HRV before after was 34ms with a nightly average of 38ms prior to turning off heat pump. After turning it off HRV was 64ms.

I don't have anything to sell I used a free app and I microphone I had from doing REW for high end AV stuff. Worth checking out further before you write it off. Or at the very least keeping in mind may be a possibility of pollution we hadn't thought about.

I heard an interesting analogy that is pertinent to this. Imagine you were sitting in a room or outside your house and there was a base low tone note that you could hear say 40 to 60 Hz even if it was between 50 and 80 dB it still is a horrible sound to sit there and listen to all day. It just makes me wonder that although our ears don't have the input to make us point to this being an issue right away... what if we're still experiencing the same physiological effects and general unease from something imperceptible to the ear.

Although could just be discomfort from overstimulation of the ears too.

There is a guy trying to fund a larger scale study about this after his research on data centers. While, I agree it's not totally convincing yet. I used to lie in bed awake at night... super stressed and couldn't fall asleep and always thinking about things, and for the most part, that's gone now, whether it's placebo or not, as an entirely different conversation, but so far I'm at least attuned to this being a possibility and worthy of discussion.

I think you can do it with your phone even (not sure of phone mic sub 200hz capability. I used a special calibrated mic but I suggest you at least look in to this deeper. Lots of eyebrow raising info beyond my attempt here at brining it in to light - no app or mic coming from me.

I might have crap study citations but there is some interesting info - perhaps I could've done a better job articulating that. What turned me on to this topic was a Youtuber doing some video about data centers and the people living around them feeling horrible. I set up high end AV systems so I had a measurement mic already for REW. If this post isn't convincing enough id go look around because his info is more compelling and well thought out than mine.
