im quite impressed with the phresh filter brand duct silencers. i pop one on both sides of each fan and id estimate 75% noise reduction easy. its heaven!

Hey guys, I just moved to a new apartment this weekend. Went from a place with no worry about noise issues and now I am getting nervous about this new place.

My main concern is the humming of my ballast. I want to build a box for it and line the inside with foam. My concern is that it will get too hot. Earlier today I placed the ballast inside a cardboard box with towels wrapping the box, took care of the noise, but it quickly got too hot.

Any ideas? will a properly constructed box get rid of the heat issue?
we built a box.. and used a exhaust fan.. to get rid of the heat.. works great.. and the buzzing isnt loud at all anymore.. before u could hear the room was there running.. now.. NOTHING and ontop of that.. the ballast heat. is now not incorporated into the lung room. so the entire grow dropped 3-5 degrees just like that.!

is it the magnetic ballasts that buzz or just something that happens to older units? my digitals dont make any noise at all

Used to live in a tightly-packed apartment block with thin walls. Cheap. Hey, I was a student! Sometimes I thought that worrying about sound from fans and such was just unhealthy paranoia, that the smell was the main thing (since I had been found out once before because of the smell, although thankfully that wasn't law enforcement who found me out). Nevertheless, I did what I could to minimize the noise, and when another guy a few apartment blocks over got busted his fan was old, clunky, and loud and it was bothering his neighbors at night - that's when I thanked my lucky stars that I chose to be smart about that thing. Now I live in a detached house and never want to live in block housing ever again. :D
 
I use a Sunleaves WindTunnel Inline Duct Fan with silencers in both the intake and exhaust. They are very quiet, and you cannot hear anything until you are in the same room.

ez construction on low budget silencer
w cheap mattress top pad foam on inside of wider round cylinder metal duct section, worked well.
likely already mentioned here. maybe ill bake more

there are many threads about odor control but one thing that is often overlooked is sound control. sound from buzzing ballasts, inline fans, wall-mounted fans, hydro pumps and/or many other things could be a contributing factor to someone finding out about your secret garden. worst part is that you wouldnt even know that they know! so if anyone has any ideas for sound control post them on here...
Man this is so true. Even talking about smoking marijuana, could lead to some neighbors listening.

To shut my Vortex 8'' i put the fan on an old couch and covered with bunch of clothes and other shit to kill the vibration and noise, With all those think to kill noise i can't go over 1/2 of the power it's to damn noisy for my place! If i let the vortex ride on full power without protection it's look like F-18 hornet jet engine :).

When i water the plant i try to not using water and walk to other chamber. I wait like 5 or 10 min or simply fill my bucket couple hour before watering, and try to water the plant gently.

I dont understand why inline fan manufacturer took 10 year to realize their inline fan are more noisy then f-18 hornet engine.. Thank Vortex!!!!!!!!!!!!!

Can anyone compare the volume levels from the S-Line to S&P's TD lines? I run an 8" TD-200 now, got it because it was supposed to be pretty quiet. Well, it isn't, really. I mean it's all relative... it's definitely quieter than some jet engine fans I tried before it, but it's not really at the volume level I'm looking for without doing some work.

I've done my best to mute the hell out of it with a lot of wrapping and duct muffler and shit but GOD what I wouldn't give for a genuinely quiet self-insulated fan. I even heard the TD silent series weren't really a huge improvement over the TD's...

So has anyone switched from a S&P TD unit to one of these S-Lines of a similar size/cfm, and can you give us your input on noise levels?

I love my panasonic Whisperline, but I do not need 0 dB, as I have a
window fan in my man-cave window, set to drive air out, that runs 7-24.
(so, there is always some ambient background noise in the cave)

...but the WL is quieter than a fan running in the same room and it
keeps my odor down and tent cool.

A nice video, but something is for sale. We need a real test where nothing is for sale!!

I ran a whisperline before the TD... it was a little quieter than the TD... but I'm looking to take it farther than that even if possible! haha. I rely on the sound of my PC's fans to mask the sound... haha... it's pretty effective as is (thanks to some isolative procedures, a custom built closet door, etc) but I would love to get it to a level where I could be running quiet enough to not think I need anything to mask. My REAL plan is to move into a place where I can get the room in the basement or something, somewhere farther from living space. But right now I gotta work with what I got...

I really like the look of that backdraft damper addition... that looks nice. It's too bad they aren't comparing the sound levels to the S&P TD series or the silent series would be even better... ah well.

Also... what the fuck... the S-series is actually louder or equal to the rebel? Fuck it then.. lol

I think it's better to buy 2x 80$ muffler and keep our old fan, the vortex s-line are well designed and look less vibrating then the other Series. ! It's on my list, i will buy one for sure, my vortex vibrate as hell no matter what i do, I do not have the choice to change sooner or later. but i think it's not enough well designed to kill the problem, the home made muffler is a must for appartement grower!

Insulated ducting, fan on rubber, good speed controller, duct mufflers. I like centrifugal blowers, they are small, and make good flow. They also have got higher static pressure that other fan. Flow don't drop, you could have carbon scrubber, ducts, bends and move nice airflow.

Your ballast relies on air circulation to keep cool, boxing the ballast will likely lead to a fire or over heating the ballast and reducing its life expectancy, I'm as suing you use one of those big box ballasts in which case you should look around for one of the slim ones, they tend to be more quiet and use their shell to transmit the heat.

or just hang the one you have so it doesn't vibrate on things.

I just wanted to say thanks for this post and there really is good info if people take the time to read it all.
I had questions on fans, and noise etc. I read all the posts from start to finish and was able to then go buy
a fan/filter combo that is very quiet, I cannot even hear it in the same room hardly. and certainly not in another room
So thanks you guys! :bigjoint:bongsmilie:clap:

AWESOME THREAD super useful. So I'm in the proccess of upgrading my set up. I'm outfitting a 4x4 gorilla grow tent, which btw I AM A HUGE FAN OF, I HIGHLY RECOMMEND SPEEDING THE EXTRA CASH FOR THE GORILLA! I This tent runs a 600w hps, two 6" max fans (one for lamp cooling one for ventilation) a 4" can fan HO for intake. All set up, the noise was becoming a concern. most of the noise was was coming from my two max fans. so after reading this thread I went to hime depot and bought a 25' long roll of 6" r-6 insulated flexible ducting. it was $30 well spent. I re ducted my fans, repacing my non-insulated 6" semi rigid ducting. I added a one foot section of insulated ducting to my intakes and a 4' length to my exhausts. the difference was insane. I was actually pretty proud of the results. You cannot hear any motor noise at all. you cannot hear any duct noise, and with the bungee suspension you can't hear any vibrations either. The only noise one can hear is the white noise sound of rushing air. barely audible through an interior door. so my suggestions, insulated ducting and bungee cords. I was gonna build boxes for my fans but now I think that would be overkill.

Yeah if its hydro, make the return line goes all the way into the reservoir, that way it wont drip.
-Also wall mount ballasts first on a piece of cardboard, also you can add rubber to the corners so it wont buzz as loud
