7.83HZ Schumann Wave Ultra-Low Frequency Pulse Generator & Audio Resonator, DC

I wasn't  judging  the students. Let me know if you ever figure it out.

No telling what these children do when they escape the influence of the resonators.

How dare you judge my students from your elitist platform.

I seriously doubt anybody is expecting old timers to hop on board the Schumann train 🚂 This is a perfect example of not being able to teach an old dog new tricks. Allow me to interject an excerpt from a review of the Acoustic Revive Schumann resonator here for contrast to idle speculation. To whit, from 6 Moons review,

Listening Impressions
Acoustic Revive recommends that the RR-77 be placed at a height of five feet or more which, I confirmed, provided better performance than lower positions where effectiveness seems much reduced. When positioning your unit, you really need to make sure it is at least five feet off the floor. I have my RR-77 sitting in an alcove above my fireplace on the left wall of my living/listening room. You can experiment with placement a little and see what works best for you. In his listening room, audio bro Stephæn found that the best performance with the RR-77 was achieved between and up behind his loudspeakers.

I had actually plugged in and started using the RR-77 before I had read up on it or done any background research so I didn’t really know what to expect. The first time I powered up the RR-77, I had some music playing and was shocked by the transformation. "What the hell!" I mumbled as the RR-77 made everything more natural, smoother and more musically lifelike - a music lover’s dream come true. Space opened up in the recording acoustic, notes decayed in a much more natural fashion and what little edge, grit or glare I was hearing on lesser recordings over the review system became more tolerable.

One aspect particularly intrigued me: You know how you can hear the acoustic signature of a recording venue in a recording? The recording has its own acoustic signature and so does your listening room and they are different. With the RR-77 powered up, it’s as though the dissimilar acoustic signatures of the recording and listening room blended and became one. This effect of the RR-77 is a little hard to articulate fully and you really need to experience it to get the full understanding. On smaller, more intimate jazz recordings in particular, it makes it seem like the musicians are in the room with you playing and yet you feel like you’re in the recording.

There ya go, like I said it's  a cure all or a curse depends on which tale of salvation or woe you encounter.  No telling what these children do when they escape the mind altering influence of the resonators.

I bought on on advice from an acquaintance.
Is it BS? Placebo? I’m not likely to believe it but I can say it affects my daughter. I don’t feel any different with it on or off so maybe some people are sensitive to it.

I'm not totally convinced on it's affect musically; it's very difficult to measure, and I'm not good at A/B tests. 
However, I teach in one of the poorest suburbs of the country. Ever year I get many of the tricky kids, especially the boys. And this year, they calmed down. At the end of the year, a completely different way of behaving. This coincides being the first year with two Schumann Resonators in the class.
Luckily I only have 12 of these tricky kids next year ( I keep six from this year, but they are no longer a problem). With a third resonator (in a 73m2 room), I'm sure to be saying the same thing at the end of the year. It does calm people.

I suspect you give yourself too much credit. What discussion? 

I unleashed a can of worms with this post and wish I could have a "do-over."  As always, GK dominates the discussion, which I presaged.  Over and out in this discussion.  Happy New Year to all.  

I bought on on advice from an acquaintance. It was like $20 on eBay, USB powered. Things are hectic for us and sometimes it boils over and things get rough around here.  I plugged it in and put it on the small table grind the sofa. Forgot about it for like a year. Consequently in that year my daughter had only 1 meltdown (mother related) and it was far more mild than usual. Fast forward to a few months ago I found it and unplugged it and threw it in my bedroom closet (aka the bottomless pit). A week later my kid just completely loses it. We get though it and a week after that she melts down again. In my mind I’m thinking things have been very chill and drama free so I can’t figure out why this is happening. Then I remember the resonator. After she went to bed I put it back where it was and plugged it in. Smooth sailing for a couple months now.

Is it BS? Placebo? I’m not likely to believe it but I can say it affects my daughter. Say what you wish but she doesn’t know it exists and her meltdowns coincide with taking it offline. I don’t feel any different with it on or off so maybe some people are sensitive to it.

The class on how to use the device was last week. Besides, there are quite a few reasons why some people don’t hear certain tweaks, like the Schumann device or the Tice Clock, several of the reasons not particularly flattering to the complainer.

You may want to consider two Tice Clocks, one for each channel.   They have the same effect as the resonator.  
Check out Cocoanut Audio’s website for a panoply or tweaks that would be of as much use as the resonators. 

I have one.  I’ve not heard a whit of difference in my very small HT room.

I have read where these new age contraptions supposedly help everything from sleep to your love life and cause everything from anxiety to cancer so take your pick. 

>>>>How paranoid can you get?

The class on Schumann resonators was last week, fellas.

One thing I did notice was the two I had in my classroom.
One from Ebay, one from Alliexpress.

I have a pretty tough bunch, some with major social and emotional needs. 

My class was a calm class. I'm putting some weight on the Schumann Resonators. Enough to buy a third one for the start of the year.

Have had one of the cheap 5v ones from Alliexpress under the bed for six weeks. Tried it last year, but couldn’t sleep.

This time round I persevered, and it is easier. Waking up less, but no real idea if it has an effect. I have noticed that I am not tired during the day, no matter how many hours I've slept.

However, when I first started using them, I swear I noticed an improvement. New tweak bias perhaps? That's possible. My thoughts:

When first used one last year:
"I swear I hear a difference. A little more depth?
Tried on a bunch of different music.
Hard to pinpoint what the difference is."
A month later
"More authority to the music; a tighter grip. A little more depth as well."
Did notice more authority when I first used them. Has now blended in as the norm. I initially felt a little spaced out.

You will very quickly hear both opinions. Of value, or not.

I have a few Schumann Resonators. My latest have been from eBay.
Two in the lounge (with speakers), one in the bedroom, and two in my classroom.

Their effect is sometimes difficult to pinpoint and the science is easy to pull apart, which makes them a target for criticism.
