Would it work if you put your inline fan inside a sealed cardboard box and cut holes for only the intake and exhaust? Not the best option but a quick fix?

Look for something called egg foam. It's basically acoustic foam and really cheap. Fill all the gaps in the cardboard box with that and you have yourself a budget muffler/fire hazard :)

The first thing that popped into my head, when I saw the title of this thread, was: "put a couple of pillows between wall and the headboard!" But I do have a trick that I thought I'd share: I hung my fan from two sets of bungee cords. This does two things, it damps the vibrations so they don't get transmitted through the floor boards and provides redundancy. Only one of the bungee cords is carrying a majority of the weight of the fan. Should it fail, the other bungee will keep the fan in place.

Hi guys. buy yourself's a varii speed fan controller. a little bit of buzz/hum but for ten of you'r
English pounds, (which is about equivalent of around 3000 US dollars) you really cant go wrong.

this makes your room very quiet. I am using a red scorpion 6" inline extractor.. way too LOUD and powerful for a home set up.
I have neighbours who live ABOVE me ,and I'm sleepin easy at night, worth every penny.

Even if it only lasts one grow (3months-ish) I'll keep buying em

I was slightly miffed at the hum... as its an extra noise. but the woosh and whirring is gone. just the hum.. which is a bit louder than an old skool P.C.

Use standard fiberglass for this. Foam is a bit dense for use in a sealed box. Bungie chords to decouple. Fiberglass for absorption.

image.jpeg Nice info on the fan .. Instead of bunjee chords you could go to a hvac supply outlet and get vibration isolators that are screw ins they work exactly the same way but look way nicer

Picked up one of the Phresh Hyperfan Stealth. 6" It is insanely quiet. Paired up to a filter, my commercial water pump is louder, even when the thing is on 100%. Highly recommend the device.

That sounds like a wise choice.

That, or a Whisperline, or Soler and Palau, will drop your fan noise
down below some other thing in the area. :0)

When you go around the side of my house where my exhaust and intake lines are you can hear it sucking in and dumping out. Sounds like a dryer vent.

Hope you have the exhaust far enough from the intake ( usualy 5' )
To stop exhaust air from being sucked back in

hey hedgehunter try the box it will work rather well.. you can also add insulation to the inside of the box to help reduce noise. i also live in an apartment and sleep right next to my room>>>>>>>>>


thnx for the response Kenbud.

JohnnyPotSeed\... as i said i think it is an issue overlooked by some growers and it could be resolved as easy as this housing..

if anyone has any other ideas too reduce sound feel free too post...

Hey, we seem have the same grow room :)
Is that roughly 1 meter square by 2 meters high?


Incidentally, next grow I'm placing a nice thick sheet of sound proofing (slightly larger then the room) under my grow room tent to see how that works at stoping vibration and sound travelling to the floor below. Fortunatly i have the room below too ..so i can observe the effects :)
I might also try wrapping my inline fan in a sheet of sound proofing (again just to see the effect). On Ebay you can pick up big sheets of sound proofing for very cheap prices (some even have on sticky side to make it easy to attach)

Wow an old thread but something I'd like to add is there is options during construction of the room.

Insulation during construction is huge, not just the pink shit but for twice the price of the cheap fiberglass you can use roxul insulation. It's anti organic which means there is nothing in it that mold can feed off of. It's also a lot better for sound. Another thing is they sell quiet-rock it's Sheetrock with a layer of material between the gypsum that greatly reduces noise.

If the rooms built you can and should hang everything for less vibrations. Cheap epdm rubber between things also helps reduce sound. Bungy cords are great. Also the use of prefilters on intakes and exhausts help too.

For soundproofing, per lab data nothing works better than cheap fiberglass. Per lab data

You would do better to use 5/8" drywall at $11 a sheet rather than quieteock at $50-$80 a sheet.

The bigger issue is decoupling the drywall from the original framing.
