It is said that the frequencies of a cat purring has healing effects. I followed up on this idea, and this is what I found.
Scientists have demonstrated that cats produce the purr through intermittent signaling of the laryngeal and diaphragmatic muscles. Cats purr during both inhalation and exhalation with a consistent pattern and frequency between 25 and 150 Hertz. Various investigators have shown that sound frequencies in this range can improve bone density and promote healing.
I found a skeptic's critique here. It is well worth reading through, but here is a little excerpt.
So... what to make of this? It seems that low intensity ultrasound has definite evidence going for it in terms of bone growth stimulation. Also, acoustic shockwaves from the patent are also cited, but my skim showed them referring to frequencies in the ultrasonic range as well (I could have missed something, though). However, a cat purr is not going to use their supplied method of causing bone bleeding.
I could find no evidence for the claims that I think would be required to support what you're asking about, thought. Namely, nothing supporting:
cat purrs themselves for healing bones, various illnesses and/or other bodily damage
acoustic waves themselves in the range of 50-150 Hz (the range of purring frequencies) for healing
For one last thought... we are quite ignorant of all the variables involved the body's healing. One's outlook, the placebo effect, stress levels, etc. I wouldn't doubt that one's psychological disposition due to the presence of a beloved pet really could have an effect -- I just don't think there's anything particularly amazing about the "power of a purr" at this particular moment
There are always dozens of reasons why something "can't" be done. That's no excuse in my book. If you want it bad enough, you find a way. That's how life works for grown ups. -- Booger
Don't be afraid to be open-minded. Your brain won't fall out.
Well, there is shaman, placebo, faith and wishful thinking that heals. It works. Almost anything can be healing if everybody involved believes it.
Then there is the scientific method of observing and measuring the physical effects of medicine with our current technology but our machines can't measure everything.
We have evolved with the frequencies of our universe, galaxy and planet so i suspect our well being is affected by it. Our universal environment has changed over time so I don't think we are very sensitive or at least we are fairly adaptable to changes in frequencies.
Marshall McLuhan said "the medium is the message." In other words, the content is less important than the frequencies. He said that devices like radio, television etc. change individuals and societies in physical ways that is more profound than the perception of content.
There are probably destructive and healing frequencies. It would interesting for some the purveyors of healing machines to do some serious studies and see if any methods exceed a placebo effect. Otherwise, buyers beware.
I used them on a dog that was expected to die over 2 yrs ago when he seized and puked and inhaled and then had pneumonia from that. He was on subq fluids, no food, antibiotic shots and still was given less than a 10% chance.
I figured he was just laying there breathing and healing as best he could anyway so I played the second youtube and a couple of others over and over from my phone.
He still is with me today Did it help? I dunno. Did not hurt
My thoughts don't feel like electric chemistry, but that is what they are- Henry Marsh, neurosurgeon.
I had a customer that was a noise guy. He was really, really into different types of random noise. He would experiment with different "junctions". I was clueless, but this guy really got into it. Typically, the "whisker" of a 1N34 would be used. The 1N34 is a germanium diode. It is famous for use in the old crystal radios. Anyway, this guy would put in 1N914/4148s, 1N4xxxs, and then he got freaky and stated putting in 2Nxxxx (2 legs - of course). I do not have the slightest idea what he got out of it. This was 20 years ago. He did say it got sort of weird. I think the human brain does not deal well with meaningless noise and starts to look for meaning, function, and form where none exists. Intellectually, that is why it is creepy. I might just play with it for a while - for fun.
Actually, I have studied some of the frequencies. One of them, I think it was like 8.72 HZ, something like that, anyway, it allowed most people to see ghosts. I have not done it - but it sounds very scientific. Apparently, the human eye is sensitive to that frequency and the vibrating eye starts to see shadows cause by the frequency on the eye fluid. Of course the shadows are bot ghosts. But it was still unexpected.
