I seem to remember you showing a quiet fan having the capacity to move 2 or 3 hundred cubic feet per minute?
Anyway, I'd think technology today would have some kind of system out there that does the same thing like what you have with noise levels below 70 db.
And, my suggestion would be to get one with as low of pitch as is reasonable (rather than anything high & squeaky).
The bigger problem might be finding the "showroom" where they'd demo it for you.
if Mrs T isn't there, I just turn them off. she's the one who can't sleep unless there's a cold draft blowing on me.
It just sounds to me like you're dealing with more than noise.
Your wife's preference to have a current of moisturized air flowing your way is a bit more than just noise. (Was it moisturized, or dehumidified?)
There's your battle of trying to be considerate, not saying too much about some preference your wife apparently has. There's the fact that the air is moisturized, or dehumidifier. Anyway, which ever it is, that's going to make the noise represent a lot more than just sound.
Those noise-cancelling headphones can be gotten used to. And, they will eliminate most buzzing fan-type noises. I had a battle with them for a time since they were a bit uncomfortable, but since I wanted noise removed and only noise removed, I was ultimately able to become fairly used to them. Or, found ways to wedge them down between blankets or pillows when I was on my side.
In your case, however, all that the moister or dehumidifier device itself represents makes the thought of enduring more hassle unbearable, I'm guessing.
So, anyway, since this thread and post is about handling offensive upstairs neighbor's noises by building a sleeping capsule of sorts and then finding the best way to ventilate it, I'm going to ask if it is alright if I post my summary again in order to close my thoughts on the matter, after all my experiments?
Or, maybe not. I may find other things to say. It may not actually be closed after all.

dehumidified. dessicated. dehydrated.
but yes. go ahead and post the conclusion. if I need to vent about Mrs T's sleeping requirements at a later date, we do have a thread for that.
What you want to use is a small centrifugal blower (squirrel cage type.) They are not only quieter than a fan, but can deliver substantially more static pressure as is required in a ducted application. Not only do they develop more static pressure on the discharge, but they can generate more suction on the intake. This could be used as an advantage as the blower could be mounted at the discharge end of the duct, further away from the sleep chamber and thus reducing the noise in the sleep chamber.
Keep in mind that the input of a centrifugal blower is usually at right angles to its discharge. This could actually be an advantage if you design your duct work to accommodate it.
Well, here's a question for you. GTCGreg,
Can one of those cheap Harbor Freight drill presses run all night?
I have a Central Machinery 12 Speed small drill press purchased from Harbor Frieght. Must have been $129 kind, it's so small. It's called a 10 inch. Must be the material length allowed. It runs 120 volts, 3.85 amps.
Could something like that run continuously for 8 or 9 hours? I ran it for 20 minutes and it seemed fairly hot.
Basically, I'm looking to boost my white noise pool. Inside the sleep capsule everything is fine, just a mild humm or buzz.
Outside it is getting a little noisy, but that's the idea. For every new and increasingly powerful pounding noise I hear from above, I add another fan or motor to the white noise collection.
So, will it run all night, even though it feels to be hot to the touch? Is that alright? Or am I burning down the house?

I can give an educated guess on that. I would guess the motor is not "continuous duty" rated. since a household drill press isn't expected to run on production mode all day, so so it is likely that the motor is not rated to have enough cooling to run continuously.

if it says something like "cont." then it's good to go. if it has a number that is how many minutes it can run at a time.
Couldn't yet find THAT particular plate. Just one that mentions amperage, etc.
Anyway ran it for a couple of hours until the windings began to stink of heated grease and such.
I shut that drill press off, but left my box fan and floor fan running.
The typical evenly-spaced pounding noises were atypically quite after I ran the drill press.
In fact, I'd currently characterize it as stunned silence.
the motor nameplate is usually on the motor, itself, and may be hard to find or nonexistent on preassembled tools.
if you really want to generate a lot of white noise ans ensuing stunned silence, you could get one of these:
I make an effort to remember my hearing protection when I'm drilling out a house. they run that loud. not quite as loud as core drilling with a hammer drill, but close.

That's an idea. At the moment, though, just doing what I can with the things I currently have.
One discovery: the box fan, tilted over onto a corner against one of the bedroom walls does pretty well if I've added a piece of duct tape to one of the blades.
Well, the unit upstairs has been empty since mid September. Trouble is, a key individual on the board was great friends with the prior upstairs tenant. And, though the official story for her having moved was one based on her "getting married" it is generally understood that there was a noise problem here between us, due to the emails I sent to the board (before I knew that the key board member was close friends with "her"), where such emails contained YouTube videos that pretty well demonstrated the stomping and clomping she was doing approaching midnight.
That embarrassment apparently enraged said board member, such that he took it upon himself to carry on with it all after she left!
How so, you ask?
Well, I heard a pretty strong thump one day, coming from the livingroom area. I managed to quickly look outside, and discovered the man with his outstretched hands still up against the side of my building, making it clear he had just slammed the side of my exterior wall! Then he bolted away, up along the side of the building close. He stayed close to the building, ducking behind hedges and trees until he was around the corner, out of view. I tried to find where he went, but since I had to smash my face up against the window pane just to see this much, I was unable to see him again anywhere else that I quickly looked. By the time I got outside, he was gone of course.
Approaching him and confronting him about it may have been an option for some, but I'm too new here to make such "accusations" of a man on the board, well liked, and his having been here for 15 years to my 1.
Needless to say, he left a warning shot in this way, telling me that this ain't over, even if she has moved.
Sure enough. I occasionally hear "unexplained" thumps and bumps (or actually, I record them via video) that wake me. Since I'm locked away in a sound resistant chamber (I'd imagine those thumps would be way worse without the chamber), I cannot get up and out quickly enough to even attempt "catching" anyone.
So, I've had to grin and bear that.
Then there was the concern for a slight build up of CO2 gases along the bed's sleeping surface. Though there is ventilation, the inlet port and outlet port are both located at the top of the chamber, such that heavier molecules like CO2 stood the chance of collecting as I slept.
With an air quality monitor I was able to confirm that CO2 managed to get as high as 850 ppm.
The solution involved running a vacuum line to the surface of the bed, or slightly lower, to suck up CO2. The "vacuum line" is nothing more than a 5 cm wide hose, running down from the outlet port. Suction provided by the outlet draws air through this hose surprisingly well. Now, readings remain below 500 ppm.
Either of the above CO2 readings is fine for a healthy person. But, for me, my dissolved CO2 runs a bit high at 29 mEg/L. So having ambient CO2 minimized is preferable for me.
The thumps have gotten less frequent, and a new owner is due to move in any time now. My BIGGEST concern is that the idiot board member will again thump such that it makes the new owner wonder if it was me!
Just downloaded our county's real estate transaction records for the condo unit above mine. It was purchased by an investment holdings firm owned and operated by the real estate agent hired to sell that property, and who is fairly good friends with the previous owner. I briefly spoke with that agent a while back. Seems he's into buying properties and then renting them out.
Nothing wrong with that except in our laws here at this particular condo, we do not allow rentals. Seems we do not collect enough in the way of condo dues to cover the typical mess some renters can create (illegal drugs, couches left out at the curb when moving, etc). Anyway, whether anyone here agrees or not that rentals have a higher statistical problem rate, we don't allow it. You are in no way blocked from purchasing here (the unobstructed acquiring of property is a protected constitutional right), but if you buy here, you basically live here too.
The board was notified of my findings. They quickly researched it and the title company declares that the "real estate agent" is set to actually live here.
Trouble is, often times when a rental is being set up, the owner lives in it for a year, maybe, and then all sorts of "family relatives" start to take over after the owner moves out.
I was asked to monitor the situation for the board. Not sure how good that will go, but I am interested in a reasonably "ran" condo. So, okay.
