Another way to reduce fan noise is to use rubber feet either side of the fixing plate and screw through them, using a suitable washer on the screw head side.

Also car acoustic deadening rubber will help with general vibration. Not sure if I'd put it in a tank, but underneath on the floor it should help. Example: eBay Store - Sounds Great: Dynamat Cascade: 10115 DYNAMAT Original 2-Sheet Speaker Kit Brand New

Also beware of corners in a room, these act like a trumpet and increase noise. If you can mount fans / ballasts away from wall and ceiling corners, or 1/3 way between small walls this should help.

John - ballasts will make more noise over time, if your's is a few years old, it may be worth replacing. Try mounting it on rubber feet, or a foam/ rubber base and aim your circulating fan towards it. A high density foam block, like a yoga block should help.

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?

im sure if you build a good box that has vents and fan(s) you could handle this heat issue. i will make up some plans for a box and throw them on here tomorrow..

Ok cool. I was thinking I'd line the inside with foam and put a pc fan on each end. Then rubber feet on the outside.

Medi user- I would be willing to bet that is the problem. Ill build the box for now and when funds allow i will invest in a new light set up. I have been meaning to jump to a 1000 watt anyways.

Go for it if you want john, but putting fans to cool off a fan really isn't necessary. The air flows through inline fans and cools itself.

People used to use these boxes around inline fans on the old overgrow site. I never tried it personally though. Heard good comments about it back then, and continue to hear good things now.

Aw man. You totally beat me to it Medi. I was going to suggest the car sound deadening equipment, but looks like you beat me to it. My only suggestion would be to switch from Dynamat to Fatmat. It's cheaper and still works.

I personally don't have experience silencing a 'room' per say. I really have much more experience quieting a grow box. With boxes, it's an issue of reducing the sound, while at the same time saving on space. But I'm willing to offer whatever info I currently have.

Other than people mentioning the rubber feet, sound dampening material, bungees, and boxes, I do have a few ideas.

The carbon filter itself helps reduce noise from the fan, so if at all possible put it at the end of the fan's path. If that doesn't work, or isn't an option, try using a duct muffler. But I use insulated ducting. You'd be suprised how much noise that reduces just by itself. Also, as far as the fan goes, you can always use a Speedster to reduce the amount of air that is flowing, reducing the noise.

I look forward to seeing where this thread goes. Anyone have any experience silencing a cab? I got most of it done, can't get rid of that 'wooshing' sound and it's currently pissing me off. :fire:

This might be waay out of line, but I wanted to know if anyone that has used a "turn-key" system could give some feedback on their sound levels. i.e. "bloombox", "producer", "Caddy".

First of all, thank you for the heads up, but it probably has little or nothing to do with sound control, which is the topic of this thread.

Second, while infared cameras might be of prime importance to you, it isn't for everyone. Infared cameras need a warrant before they can be used on residential houses in the US. In addition, FLIR cameras usually don't pick up small time, personal grows. Only commercial ones.

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.

I have built a couple similar dampening boxes out of card board boxes with good success. Just packed some foam or blankets around the fan, did worry a little about static discharge.

On one box the fan runs into the box and out through a carbon filter, still inside the box with the lid partially cut away. The other the vent enters on side of a box and goes through the fan and into another vent tube before exiting a carbon filter outside of the box.

My system is not silent but you'd have a hell of a time figuring out what it is and finding it. Oh the fans are the Home depot duct boosters, the 8" fan is actually a good bit quieter than the 6" and less than $5 more, just as a heads up.
