Quiet. The Neighbors Can Hear You (Sound Control Thread)

[skunkyhead]

silncers work a damm treat! Got a 130w fan with 2 silencers on it. Upload pic soon. Only prob is,it's still a little to noisy for my likings. Any body know how i could silence it more? Was thinking of putting up a fake wall to reduce noise but don't know what to use as insulation? What has great sound deadning properties?? Any and all help is appriciated!

The noise now you can probably hear is coming from the actual fan, If I were you I'd make a box for it and fill it with expandable foam.. he foam sets hard so if your not happy with it you can take it the box apart and peel off the foam..

 

[skunkyhead]

cheers! i'll give it a shot. Don't know if will work caus room is a bit tight.can't suspend either. Does anyone know if another silencer will work? Thought it won't caus not connected directly to fan so therefor won't silence. Any one know if true or not?

 

[skunkyhead]

Playing around with cheapest option first.Insulation bats. Let ya know if work or not...

I'm open to all any any idea's

 

[skunkyhead]

ok. insulation bats worked a little but not as much as hyped to be. I can say the same for insulated ducting. I am running r6 ducting throughout. Yes it helps but not a great deal. Well in my circmstancs anyways. But as always it all comes down to individual set ups.

With the box idea...Is it better to go thick walled i.e 19mm part board and have less foam OR go thin like 3mm and more foam? And i'm guessing to bigger the box the better. BUT having said that,do you comprimise noise when the box touches the walls? (refer to my pic above)

All info is greatly appriciatedkiss-ass

I to am about to face the challenge of nice quiet no sounding fans in my room.
I thought of this.Get some thin chicken mesh.squash it all up and make a seperate piece of ducting about 3 or 2 foot long 2 or 3 of these things would be the go.put as much chicken mesh as you can in there without putting holes in the ducting. i was going to reinforce ducting with strong tape.Then i was going to make 2 seperate boxes out of ply use that dynamat car sound deadening stuff to line it heavliey and then cut the holes out to feed the duct threw then put it all togther.Couple of hooks and suspend it from my roof in my room.

the hole chicken mesh idea is to take up room in the ducting.While still letting airflow fly stright threw thier.In other words walk into a empty house it echo's its ars of walk into a house that has furntiture it dosnt really echo.Thats kinda were i got my idea from lol

the thicker the better i would say with the wood and a shit load of foam.And yes if your fans are touching the walls i could only imagine that ther would be vibration from that when running. foam it up

 

[skunkyhead]

ARRRRGH!!! This is driving me nuts!!! The only way the system can be installed is upright with touching walls. The vibration don't matter. It's the noise! I tried the foam box with no luck Can't susspend anything either so therefore can't lie system down. So far the best thing on there to reduce noise are the Silencers! Highly recommended if room allows it. I think I'm going to have to go outright and take the biggest $ sucking option Industrial Sound Proofing Insulation. Down to one other option. Comply back fill the wall with bats. It's 1/3 done with foam box and noise is only muffled slightly.

Is anyone out there who runs a Completly Dead (or close) silent carbon filter set up? PLEASE post how you did it!! Noiseis not an option for me! Pretty Pretty please with extra skunky thc on top of your fruity skunky bong hits!kiss-ass

I am contemplating a generator but fear the noise factor. I'm thinking 10k - 12k watts. Can mufflers be attached to drop the db level? Any help would be greatly appreciated.

I am contemplating a generator but fear the noise factor. I'm thinking 10k - 12k watts. Can mufflers be attached to drop the db level? Any help would be greatly appreciated.

I've been running an 8,000 watt portable generator to supplement my electricity for the last few months. I built a small shed 8 foot by 6 foot, and went to the nearest thrift store and picked up a bunch of old mattresses to line the walls of my room.

I cut a hole in the roof and installed a 1500 CFM power vent to get the exhaust out of the room, and cut three 4 inch holes in the bottom of the wall closest to where the intake was going to be on the generator.

When the door is closed, it's pretty quiet. When you're standing 10 feet from it, it sounds about as loud as a pressure washer that someone is running a block or two away, fairly quiet. If you have a decent sized backyard, this is effective enough to not hear on the other side of a fence in the neighbor's yard. I don't have a DB meter, but I would say it's maybe 10db with the mattresses and door shut. It's about 90-100db without insulation.

I just purchased a 15KW Onan residential standby generator last week, and am in the process of installing it. It's HUGE, weighs over 1000 lbs, is powered by either natural gas or propane on an inline 4-cylinder engine, and is about 60db with just the exhaust system. I'm hoping that when it's installed and running where the old generator was, that it will be completely inaudiable with the insulation in place.

At the very least, it will be EXTREMELY quiet. I should have it in place this week... gotta take the door out to fit it in the shed first. (I should have planned better when I built it... but I didn't anticipate ever putting in a massive generator!)

Hope this helps

Thanks BigT. With 1500cfm it sounds like you have any heat issues worked out as well. Bigger may indeed be better.

 

[bigt8r]

I wanted to make sure that there was plenty of fresh air for the generator to consume... I figured it would run pretty horrible if it was running off of exhaust air, especially on days I run it all day. The power vent sucks the exhaust gas out, and with the holes at the bottom, sucks fresh air in. I still wouldn't want to hang out in the room with the generator running, but it's considerably better than nothing...

Oh yeah, the exhaust system on the new generator is threaded steel pipe to a muffler, so I was going to see what happens when I attach more pipe and more mufflers in-line. If I can get it quiet enough, I'll just pipe the exhaust straight out.

Here Here to Johnny. Havnt set up my room yet still in planning stages but I use to be in a band back in NSW and our jam room was basically two shipping containers dwelded together under friends house. Im sure you can imagine the soung in there The neighbours sure as hell didnt have to imagine ; > any way after a few foam matress tops (bout inch thick) and a hell of alot of egg cartons you couls bearly hear a thing.

 

[purpleplantsmoker]

There is always that egg-crate foam mattress padding too. You can easily line the adjoining wall with it for cheap. Disperses the sound waves, preventing penetration through the walls.

in need to know how to grow, n e pointers on space or equipment

 

[Jay_normous]

Here is a few pics of my grow..
This is my first scrog grow.

Im using Lumatek 250w ballast, 2 4" muffin fans for in / outlet and a osi fan..

Note the foam behind osi fan.. this kills any sound echoed from behind and the corners...(will paint white when I get round to it)

Also a pic or two of my clone & veg room..

My exuast fan is linked up to a carbon air filter however has a sheet of thin cloth between them both..
The same happens with the inlet too.. by doing this lower the noise of air pulled by the fans.
My muffin fans are mounted to foam thats been cut out inside the same size as the fan turbine, them mounted it on to a small sheet of 1/2 inch mdf also cut out the sime size as the fan and use a hot glue gun, best thing ever it was..

The result: silence.... well cuffed with it...

 

[possumjeep]

Would vibration isolater mounts for automotive use would work well to cutt down vibration niose.

I got some spares from when I bought an MSD box that Im gonna try and mount my exhast fan on

 

[jigaman]

hi all i need a lil help if thats ok
i just got a 100x100x200 grow tent and i have got a tt125 inline fan and five meters of duct and 9inch fan for inside and a cooltube with a 600w hps
with six 11L pots and im using coco for my cheese cuttings but im not really sure how to set this up without it being loud will the fan be quiet in this tent as i have neva used a tent before

 

[Bluemax]

i have the same size tent buddy,my fan is on the outside,and its well,loud,only had enough ducting to cover from carbon filter to cooltube inside tent,and then from cooltube outside tent to the fan(fan is mounted sideways on wall bracket) but the end its spilling air out of has no ducting after it,its pretty loud,hopefully if i add more ducting that side,it should be all good.

i dont think your meant to put your extraction fans INSIDE the tent

the 9 inch air circ fan should be fine in there,its the other fans that make teh noise

 

[DLC420]

Due to my location, I'm lucky enough not to have to worry about sound issues... But, I had to see this post!

Bad-Ass suggestion!

I would have never thought to suspend it like you did!

yeah rly good suggestion not bad at all

 

[tbudmaker]

had t same tought but 2 c u put it it2 use like tha makes sense cheers bud
