Keeping Quiet

[007grow]

ok so I ran out this morning and bought the 10" insulated ducting figured first test would be my carbon filter which is a 5ft free standing filter with an 8" fan blowing through 8" insulated ducting. Cut a matching 6ft run and stuffed one inside the other5 fired that bad boy up and holy shit this works great anyone trying to minimize sound from big inline fans needs to try this.

I can still hear noise when i put my ear to the filter but the blower in my a/c unit is the loudest thing in the room now.

Cool call on the double insulation.

My old elicient fan was getting real loud, so I researched a little and gave the Can Max 8"

http://77hydro-store.stores.yahoo.net/canfanmaxfan8.html and man this thing is quiet, powerful, and easy to install....I pulled the insulated ducting over each side, taped to the fan and together, and you can't even see the fan in there anymore....Did I mention QUIET! Definitely improved quality of life!

Thank you so much as soon as home depot opens up I am buying 10" so I can wrap all my 8" double over I can hear so much noise actually coming through the ducting even with the insulation and i remember what a difference it was going from normal 8" to big old insulated ducting. Only makes sense that doubling it up would make double the difference. I also hear a fair amount escaping from my 5ft tall carbon filter.

Cool. It Is a tight fit!! Works best with 2 people.
Kinda gotta bunch it up and pull some through.
Took me and my wife about 30 mins to do 25 ft.

I tried that one...........Sounded like a jet plane taking off! Was too loud for me.

One in the other huh, nice.

Thanks for the tip.

 

[DIGITALHIPPY]

im so glad noise isnt a concern for me. i only try to quiet it for my own sake.
the can-max would be a nightmare to quiet down. all that extra supplies must add-up, but for the people who cant make noise i guess its a gotta-do.

Quiet!!! Ideas for noise free growing thread.

Quiet!!! Ideas for noise free growing thread.

Trying to have one stop thread for ideas and technologies relating to keeping our grows silent!

This has ALWAYS been a major issue for me, so I assume there must be many others needing to quiet things down.

Big silent blocks!

Big silent blocks!

The best ,although bulkiest way I have found to silence things is fiberglass insulation. As it is a nasty irritant, I do not remove it from its' package,they are kinda like giant building blocks!

I have a 3800 cfm squirrel cage blower mounted in an mdf box (2'x4') I stacked a couple of cubes of this on and around the box, now it whispers!


Downside is requires a bit of space.

An alternative would be to take the ins. and pack plastic bags full to use wherever needed.
I have done this, works well, but it is not as dense as the factory packed cube. And you gotta handle the material.

Maybe there is a way to carve up the blocks (halves, quarters ,shapes,etc.) and still have enough factory packing to provide effective containment of the product?

Is there a good alternative to fibreglass? I hate that stuff.

edit: apparently home improvement stores offer recycled denim as a no-itch alternative

 

[guest8905]

I am very interested in furthing the silence of the indoor grow!!

i think muffle boxes for fans are great and the fiber glass idea is awesome, i never thought to just leave it in the package haha nice

i was thinking about lining a room with some sound proof matting like in a music studio,

also double pane sound proof windows work best imo (think ace ventura )

hangingn fans from bungees can reduce fan vibrations too

nice thread

Hi Sunnydog,

Fiberglass does suck for a bunch of reasons: 1. not real good in the lungs. 2. It is generally a poor sound abatement insulation especially in walls, because the fiberglass fibers actually conduct sound; it has some uses, people do use it in fan air mufflers or silencers.

*Dealing with sound and smell are overlooked the most by growers.

I'm almost finished with my room build-out. I may start a thread about it this week.

I am removing the fiberglass insulation and replacing it with the following:

http://www.homedepot.com/Building-M...splay?langId=-1&storeId=10051&catalogId=10053

This is being placed on all non-cement exterior walls. It is $29.00 per sheath. The other big box has the same thing (different brand) for about $30.00.

This stuff is easy to cut and transport. A lot of cool thing you can do with this stuff. Sound abatement is top notch. Sound insulate a grow cab?

For the interior walls I used the following:

http://www.homedepot.com/Building-M...splay?langId=-1&storeId=10051&catalogId=10053

This will run you $8.00 per sheath at Home Depot. This stuff is really a pain in the ass if you have to due a lot of cutting etc. Hard to transport without a truck. Heavy. Works great!

It all depends on the size of your grow.

I would also pick up some reflectix (radiant barrier) at Lowes $40 per 4 x 25

I hoped this help a little.

No itch denim would be great.
That sound board stuff looks pretty cool, havent seen it yet.
Idea is to leave it bagged!
I disagree about F-G being a poor sound deaden-er; as far as I know it is amongst the best.

Do not use where it's fibers can be blown around.

i have been looking into switching out my foil ducting with a plastic alternative, we use flexible, super tough, plastic 6 inch ducting at my work that has a smooth inside...i think switching out all my foil ducting for something similar to that will kill most of my noise. the foil ducting may reflect better but all those hundreds of zig zags has got to increase drag and noise quite a bit. i was toying with the idea of using some sort of permanent pvc or aluminum ducting system but the only way to handle curves with those it seems are sharp 90 degree turns, whereas flexible ducting can be bent more gradually.

another thing i was looking into for noise were those duct mufflers, supposed to absorb some of the noise in a ducting system. but upon further inspection it seems all a duct muffler is is a section of the ducting that is a few inches larger in diameter with a layer of acoustical foam on the inside...if these mufflers really do work then it seems it would make much more sense to spend the money on rolls of acoustical foam, and work it in wherever you can, for fan mufflers, ducting, exhaust ports...though i have not tried it yet i plan to order a piece of that acoustical foam off ebay this week just to see if i can make at the least a diy duct muffler...

on the fiberglass note, one thing i was considering before i started my cab, was to line all the walls with fiberglass, and build a second box that floated inside the cab, on a layer of pink panther on all sides, squeezed tight, to completely noise insulate the inside of the cab from the outside, but i gave up on that idea because it seemed like too much work and i'm lazy at heart.

Anyone try a fan in a box w/expanding foam? Thinking that might nearly silence it. I'm gonna give it a try & see how it turns out.

 

[laughingmoon]

I have my 4" in a rubbermaid 18 gal, with expanded foam to the top. The noise is all in the ducting. I'm going to put 6" ducting over my 4 inch, and fill the gap with that denim fill I posted above, I think.

expanding foam,contrary to intuition, IS NOT a very good sound blocker.
IMO, it is actually quite poor at sound control.

Filled a hollow door with the shit once, actually got louder!

My rule of thumb when looking for sound deadners is to tap on it;
if it makes noise(think styrofoam) it will not work well.

Fiberglass and shredded denim are quiet materials.

This was me Been awhile since i ran into one of my old posts.
But anyhow, i sold that shitty loud 6in Vortex. Got me a new 8in ValueLine. WAY more quiet, i even ditched the box and it just sit's on my filter now

some pix, kinda the same thing
