Do sealed rooms really control odor?

Thanks for the all the contributions to this thread. I also read moses’ very informative thread.
I’m in the very preliminary stages of planning, crunching numbers, considering layout, etc., for making the move to a sealed room. I already run a natural gas CO2 generator. If I go sealed I will be ripping down existing drywall, insulating with spray foam, sound board going back up instead of drywall, insulated exterior door to the room, mini-split, etc.
Whether to run a scrubber or not has surfaced as one of my first considerations.
I realize there are lots of variables involved but the one thing I noticed is that no one who runs a scrubber mentioned if they can hear it... ?
One of my main reasons for wanting to go sealed is noise reduction. I want to be able to stand outside my room and not hear anything, or for that matter, anyone standing outside it not to hear anything.
I realize how well the room is insulated, the scrubber fan’s size and dB rating come into play, but I’m wondering if, in general, folks can stand outside their room and hear their scrubber running...
I like the idea of how the gnome does it. I like the idea of being able to go into my room and to breathe deeply and embrace the stank in full-force!
Any thoughts?

I run a regular Fantech 6" on a speed control at low speed - very quiet.
Use a mixed use fan on a speed control - even quieter.

get a big fan, run it on low.

Sealed room or not carbon filters are a must. I don't care how sealed the room is it is going to escape. Unless of course you are not doing it right. I know a guy thinks filters and such are stupid. Its because his weed does not smell, its hay.

Thanks for your input, guanito.
If I do this I’ll need to go with a bigger filter than I have now. And I can hear the one I have now run when I’m in certain rooms if there’s no tv or stereo on. I know insulation will help considerably, but I guess I just won’t know until I test it out.
Thanks for the laugh, Lester!
I guess I should know better. That is, I should scrub the air. I had an incident years ago that, at the time, concerned me a bit. It speaks to Mikell’s point about acclimation. A run was done. Most of the flowers had been manicured and were drying in grocery bags. There were a few plants still hanging to dry. This was in an enclosed room in the basement with a carbon filter running 24/7. As far as I was concerned, the house was stink-free.
Had to have the satellite provider out to adjust the dish. A couple guys in their early twenties showed up. As soon as they pushed through the front door —the storm door hadn’t even closed behind them yet —one of them turns to me and says, “got some catnip, huh?”
Uh, Uh... What do you mean? I don’t know what you’re talking about...
It’s just that I was thinking (hoping) that going with spray insulation would truly seal the room up so that nothing could escape. Except of course during my coming and going from the room.

There's all sorts of things to be done if the sound still carries.
Rubber bands to hold the can/fan, mufflers, a run of insulated ducting from the fan, insulating the fan. You'll still get high velocity air noise but with spray foam, I doubt you'd hear shit from above/outside.

I have this problem to, Everything is i rubberbands and so on, its all good, but the outtake vent pipe is a high air sound when its going out.
How can i get this down? what you mean with spray foam? spray foam the hole vent pipe at Place?

silencer before going outside.

I used all the above, but found that a gel available used in hospitals to remove orders from Operating rooms, blood products works real well. Just put a bit in a tray and it does it. every few days add some more. I forget the name, but I learned about it working in hospitals.

Heck yeah !
The tightest grow space I ever had was a closet in a studio apartment.
The closet had 2 doors.
One door was sealed with RTV. The wall had 2 ducts (in and out).
And the door had a sealed - well, it was sealed.
Anyway, it allowed me to send 99.99% of my skunk smell to share with the pigeons (6 stories up).

I think you’re probably right.
And I wouldn’t care how loud the air rushing inside the room is, as long as I can’t hear it from outside the room — if I do have to run a carbon filter to scrub the air.
Maybe I’m just being too hopeful, but I think if I do the insulation right, even sealing off the electrical outlets, I may be able to eliminate the scrubber.
I’ve used this spray foam insulation before and it’s really nice stuff. If anyone’s interested:

As noyd666 suggests: use a muffler/silencer before venting out. I used one years ago and while it didn't solve my problem it did help a great deal.
For your particular situation it may be the answer.
I was having the same problem. I had an 8" fan pulling air thru my filter, then light , and out of the room. Had the fan within 6" of the exit of the room. The sound coming out the other side was like a jet engine. I moved the fan a about 2 more feet away from the exit, and now I can't hear it until I'm right on top of it, and even then it's barely audible.
Edit: To be on topic, I have run a couple sealed rooms. Having everything sealed up tight, and a filter inside the room, plus filters on air cooling for the lights and a filter on the AC worked really well. I agree with what was previously stated about harvest time. That's when you can't seem to have enough air scrubbing going on, lol. As was mentioned before, negative pressure is king, and it also seems the lower the humidity of the air being scrubbed, the better the results.
Aye, frequently unmentioned but stated by manufacturers is to run carbons at less than 65%RH. I imagine (and you can too!) it loses efficiency on a sliding scale.
Mufflers help, I find moving the fan back from the exit (as mentioned above) and using insulated ducting to be more effective.

insulated ducting is a must, makes a big difference in noise and condensation. phresh fans with speed control are excellent. I noticed double triple og has a filter on ac? got a photo at all?
It was one of those portable AC's. Took a 4" to 6" inch adapter and put the 4" end on the hose from the AC, then the 6" side went to 6" inch ductwork, hooked up to a 6" fan and filter. Sadly no pic, that was a few years ago that I was running that op.
duct mufflers are your friend ..not hard to build either...yeehaw

your intake is too small. larger diameter ducting will reduce noise.
