My Journey through life...

strictlygentle​(dom male){Queen Alex} - I... wat. A healthy young adult can hear down to 20hz. Basically everyone, young and old, who doesn't have significant hearing damage can hear down to at least 80hz. I can easily here down to 30ish even with hearing damage from ear infections. This would totally be audible, and if you can't hear it, most likely it's because your system can't reproduce it. Sound engineers routinely pop in high pass filters to try to get rid of some of this noise (referred to as "AC rumble") on recordings because many times it's impractical to avoid capturing it and, yes, most every human alive can clearly hear it. This may or may not have an infrasound component, but this is not infrasound.

Additionally, if you make the wise decision to use the correct tool for the job, getting the frequency with the peak amplitude out of the sample is approximately a 15 second job with any spectrum analyzer. It would literally take me longer to get the file from you than to analyze it and tell you what the peak and power range of that noise is. The computer can do all the math for you, easily. In fact, it already has, which is why you can see it spans from 200hz down to something. You probably don't know what the bottom is because I doubt the capture system was designed to record frequencies much below 10 or 20hz.

And while the evidence is pretty shaky, assuming infrasound can cause the effects you speak of, most studies that have found effects show that it needs to be much, much louder to cause the effects. I've got news for you: infrasound is everywhere and you're being bathed in it right now. If your family in NC were really that sensitive to infrasound, they would be completely disabled by the normal world we live in by the constant effects of it.

*shakes head* ghost hunters.

Devotedsub​(sub female){His} - Very interesting investigation you have going on indeed. I very much enjoy the stories you tell and the new things you teach me about investigations of the paranormal, since I have always been fascinated by it. I love how much you work hard to help people out so they can figure get to the bottom of things.

Also.. People can agree or disagree with what you put in blogs ... My theory about that is in my profile. Personally, I don't mind people to disagree. I'm learning to just ignore rude or disrespectful comments.

Please keep doing what you love, you're good at it. 😘 ❤️

strictlygentle​(dom male){Queen Alex} - Confronting lies with truth often feels rude to the liar, but we must not allow ourselves to become confused and believe that the truth is objectionable because it sometimes feels bad.

Rude would be nitpicking the small technical errors and white lies that don't really matter (like that his "spectral view" is a spectrogram), and then using them to call the OP stupid or something. I don't think OP is stupid though; either dishonest or badly, badly mislead. More likely the latter; some people choose dishonesty, but most people don't.

Unless I just didn't realize that this was a fiction blog, in which case, my humblest apologies for this wildly inappropriate literary criticism.

If I have in fact read the blog correctly, then OP is clearly trying to pass himself off as a "responsible investigator" and slathering his claims in verisimilitude. The problem is that what he is saying simply isn't true. Worse than that, it's likely to be harmful, for the same reason that fake cancer treatments are.

See, I have no reason to care at all if this is just a silly hobby. I have plenty of silly hobbies of my own. But I also have no reason to doubt the veracity of OPs claim that there is a family experiencing traumatic things. I have very good reasons to doubt that they have anything at all to do with infrasound. I have very good reasons to doubt that our "responsible investigator" has the necessary toolkit to make a reliable determination, even if infrasound ultimately is actually responsible.

If this poor family buys OPs claims of expertise and experience - claims which are obviously false to me as someone with some expertise and experience in the audio field - best case scenario is that they waste a bunch of time and money that could have been used to hunt down and fix the real problem. Worst case scenario is they blame themselves and fall deeper in, a feeling anyone who's ever been in an abusive relationship ought to be able to empathize with.

Knowing nothing about this family or situation, I can only make a wild guess based on generalizations. Balance of probability: This family has someone in it experiencing a real, so far likely sub-clinical, mental health issue, that the rest of the family is responding to. Emotions are contagious: one foul can kill a party. Empathy and conversion disorder are real things.

A responsible and ethical person would try to direct the family to the help they need, rather than giving "help" that the "investigator" personally benefits from (even, maybe especially, if that benefit is merely a distraction from boredom).

I may not be an angel, but I am on the side of the angels. On the other side are the hucksters, abusers, gas-lighters, and others that manipulate people and manufacture their consent to give their exploitation a narcissistic veneer of morality. Let that sink into your heart and your head and make an informed decision about who you really want to be.

But hey, I'm apparently rude and disrespectful, so just ignore me.

Devotedsub​(sub female){His} - The thing is.. People have different beliefs and ideas about things. Your ideas and beliefs.. You are free to express. As is he... If he believes in paranormal, and do the folks who had him do the investigation, than honestly, that's their call. I'm really getting sick of seeing people putting other people down on here, for what they believe or how they view things. If you don't agree, simply move on..

Devotedsub​(sub female){His} - I should also add, the more I think about it, the more I think.. Wow.. Maybe this is the reason people struggle in society with another mental illness.. If you want to bring this up... Anxiety (because they can't feel comfortable expressing things for fear they will be attacked) and depression because they often feel attacked or criticized. When does it end?

strictlygentle​(dom male){Queen Alex} - That "[sound] under the 200 Hz range. [...] probably can't be heard, by a healthy young person" is not an opinion - it's a testable claim about reality. The tests have been done and the results are in: Humans, especially healthy young ones, can hear sounds under 200Hz. They can hear sounds down to around 20hz. Sounds lower than that can be felt. https://en.wikipedia.org/wiki/Hearing_range

That "[infrasound] can [...] do things like make people feel uncomfortable, give them chills, make the eyes [...] shake so they see shadows" is not an opinion, it's a testable claim. The evidence on this one is not definitive. There are various studies, some rather good, that make varying claims about infrasound and what effects it causes. For what it's worth, many sound engineers mix infrasound into their horror movies on the hopes it will enhance a sense of unease or fear, and movie theaters can reproduce it, so at least some people smarter and more talented than me believe that it's at least worth taking the time to screw with infrasound in a production. I don't have a strong belief in infrasound either way at this point, because I need more evidence, but I can certainly see how it could cause a sense of unease. If my nipples suddenly start tingling without apparent reason (because I can't hear the infrasound that's causing it), I can certainly see how that could produce some anxiety!

However, there is infrasound all around us, all the time. Nobody lives in silence and anything that can move air produces sound. Even the earth under your feat is probably producing some infrasound right now. So somebody sensitive enough to infrasound to be bothered by an HVAC system would likely have other difficulties in life as well, as they would be constantly exposed to levels of infrasound that are harmful to them. It's not as if their house or whatever has the only HVAC system in the world.

This being the wrong tool for the job is an opinion, but since the OP isn't able to extract the information he wants from the tool he's using, it's one with a quite a lot of weight to at, as the OP himself is implicitly admitting as much.

Everyone is free to have their beliefs, at least in most countries, but that doesn't mean that their beliefs can't be true or false. For me, I prefer and try hard to believe as many true things and as few false things as humanly possible. Believing true things and disbelieving false things almost universally leads to a happier, healthier, better and more productive life.

I didn't put anybody down. I simply presented some factual information to counter the false information. If you believe otherwise, please feel free to quote my calling the OP an idiot or stupid or whatever you think the put down was. Criticizing beliefs -- especially obviously incorrect ones -- is not the same as criticizing the person, even if it often feels that way. And if OP didn't want to have his beliefs criticized, I have to assume he would have posted in a forum where it wasn't so easily possible to criticize. Or at least would have asked for people to refrain from criticism.

I haven't been rude or disrespectful or done anything ethically wrong. But I do notice you completely ignored the very valid and reasonable concern that he might - even if unintentionally or with the best of intentions - be participating in or even doing harm to this family. I guess I know where you stand, and I sincerely hope that your stance doesn't result in harm coming to you. That would be incredibly sad. To me, the potential harm to this family his more important than whatever feelings you and others are having about my posts, so I'll kindly choose to not take your advice to move on and continue to try to raise the truth and rationality waterline whenever and wherever I can.

Anyway, I've said more than my fair share on this post, so I'm outta here. Accuse me of whatever you want, I'm a safe target now because I won't fight back.

Devotedsub​(sub female){His} - Or he could be helping them! It is Your opinion. And that is all I will say too. I didn't ignore it, I said I was tired of people putting others down for their view. Which is exactly what you did. You don't have to agree. But you don't have to attack. Thank you, for moving on.

rare jewel​(sub female){none} - Hmmm, I know how we're all about free speech, venting and general information to name a few. I dont think any retort should include sarcastic, snarky and down right rude comments.
There are other ways to disagree. 🤔
Now about Your blog...love it!! The paranormal is something I've long had an interest in but never had an investigator aquaintense to discuss/ hunt with. So thank You for blogging on this subject.
