u dont need a warrant to use an infared in residential areas in the US. i got picked up by one in my teen years stealing fireworks out of a guys garagewith like three other kids. cops all swarmed with guns at pointed at us and shit. but u definately dont need a warrant to use one.
You're situation is a little different. In pursuit of someone, such as the scenario you described, police can use IR. Police cannot use IR to surveillance with out a warrant in the U.S.

I would imagine that these guys fly around with FLIR going nonetheless. They couldn't use it in court, but they'd pick up some good prospects for a drive by during the daytime. Now you're on their unofficial radar as having an odd heat signature.

That's why my little grow is in the center of the basement, and I vent everything within the house. No heat sig, no vented smell for dogs, etc.

Everyone is going on and on about duct mufflers/boxes for your fans..... Pick up some insulated ducting from lowes. Its around $25-30 for 25'. It's amazing how well this ducting cuts the sound of my 424cfm 6" inline.....takes it down to what a 170cfm 4" sounds like on medium-low.

The boxes block the sound from the fan itself, 'cause the boxes are massive / heavy. The fan motor and turbulence vibrations (sound) come right through the metal fan housing, so while I agree the flex duct helps, you need some mass to stop the mid and lower frequencies.

You are right, you can still hear some of the mechanical noise, but it cuts out all of the air movement noise, which seems to be most of the total noise. Also, just to clarify, I'm speaking of insulated ducting, its got the flex ducting inside of a layer of fiberglass insulation wrapped in black plastic, it also doubles for a light block to keep light from leaking into your other tents/rooms if they are connected....

I have the 8" windtunnel fan with the lowes insulated ducting too and there is almost NO noise coming out of the hose. I can kinda hear the fan still even with my box I made for it but its quieter than a normal house fan on a stand. I am on laminate flooring and I bought some insulated white foam board from lowes too. It comes in a 4x8ft sheet I believe and comes in .5 to 2 inches thick. I put that under the grow tent to cut down the viborations to the lower neighbors and that worked too. Next grow I am going to wrap the fan in another box made out of cardboard and line it with some sort of insulation. I like quiet!. I just build a clone box out of cardboard and used one 140mm 60cfm computer fan that is rated at 16db and wow I can not even hear it working. I have to put my hand over the light trap I made for it to see if its on. Wish my big fan was that quiet.

might be a little more expensive but you get what you pay for, get 1 or more 4x8 sheets of "sound barrier insulation" contractors use it in residential attics to muffle the noise of any indoor air handlers, exhaust fans, etc. Dynamat (yes the stuff they use to muffle car audio sounds) has worked quite well for me and also adds more reflective surfaces to your grow room.

If you want to block sound you need heavy material. Massive material like drywall. Cheap and very heavy. If you're looking to absorb sound, not so easy unless the sound is high frequency (pitch). Insulation works well in that case. Compressed fiberglass and foam is what is inside these short mufflers. Insulation and sometimes baffles.

So if you want your room more soundproof consider using 5/8" drywall instead of 1/2". Or double up on the 5/8". Treatments ON the inside of your grow room, like foams and fiberglass will quiet the room by absorbing some of the echo, but not do anything to soundproof the room. Drywall on the other hand will stop much sound.

Yeah. If my tv isn't on you can hear my little computer exhaust fan running. I have to get some tubing and a box. Kinda useless to have a secret closet that hums and whines.

Any way to stop the sound of air going thru scrubber? I have a 3'x3''7' tall closet,scrubber mounted in top left corner,10" duct going thru ceiling into 90 degree elbow which is connected to 4" htg fan in attic. I eliminated vibration noise from fan with a 1" styrofoam cushion between it and floor,i've wrapped all the ducting in insulated duct wrap,i removed the shelf the scrubber itself was sitting on as it had a vibration and bungeed it. The only sound i got is the air being sucked in thru the scrubber in the closet.Being as i live in a small studio apt above my shop the sound is noticeable but kind of sounds like my furnace running.Anything else i can do or just live with it?
 
I do not know much how to use control sound system, that's why I found your interesting site after many days searching on google. Hope that I will learn many new things from all your post.

Burninbush... if you get a bigger filter this helps a lot as the air travels through it easier as thats what you can hear.. air struggling to get through the filter
