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

[orangesabc123]

Anyone familiar with voltage reducers for fans?

Specifically how reducing volts correlates to noise or air flow reduction? Also which type would be best suited for said purpose.

You can easily get acoustic foam, the type they use for studios. Some is very decorative, so having it covering walls might not seem so obvious. One could always just have some musical instruments or sound equipment sitting nearby as well. Should anyone be in the room and ask, its easy to just say its so you don't disturb the neighbors with your music.

Old thread but the acoustic foam does not soundproof, only reduces echo so is a waste of money... fibreglass, chalk but don't buy foam

Agree 100%. In fact foam can conduct vibration from one side of a wall to the other. Exactly what we're trying to avoid

I almost completely quieted my fan by putting it into the attic, using 6 insulated ducting, hanging it all suspended with (rubber snubber) bungee cords, using a 8" duct muffler and 8" fan controlled by a small variac to control the speed. Those speed controlers at the grow shops all suck! Undetectable unless you knew it existed and were trying to find it. Super stealth.


Hope this will help someone else. Works kick ass for me.

A general truth regarding isolating heavy things like this fan, or a pump, or a rooftop AC unit - You Want Oscillation.
You want an attachment that you could theoretically bungee jump from.

BB's rubber cables allow the system to oscillate. That's why they work. Substitute rigid cable (or rubber that's too stretched) and you have no oscillation. You wouldn't bungee jump with a solid cable, either.

Hey guys,

I'll power a 250m3/h Torin, throught a multi output transformer (80, 110, 160, 200, 230V), with its outputs linked to a selectror, one of the position would be the off one ...
My question is, should the off position, be next to the 80V or the 230V one ?
Nothing seems wrong with starting a three-phase motor with lower voltage ...
What's about the Torin ? I'm wondering about the "launching capa" ...

any ideas on that ?

Guys, i checked this in a growshop: http://sativagrow.es/tienda/cyclone-/9212-extractor-vortex-iso-150mm-500m3h-cyclone.html and i was amazed to say the least by how silent it was without any ducts at all! I imagine with soundproof ducting this would rock. At least the 500m3/h model i checked. Of course it is pricey, i could get 2x500m3/h extractors with that money (rvk models or something similar).

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.

Remember if the fan is screwed to a floor beam or ceiling joist that nose will go far. Just wanted to mention it.

Just a reminder that the quote from Johnny is not correct. Soft, low-density absorption has insufficient mass to prevent sound from penetrating walls. The soft material simply reduces the reverberation (echo). It does not soundproof.

To soundproof you need mass, which is why cheap 5/8" drywall works so well. Damned heavy

nice thread 123 this issue is often overlooked,and can lead to big issues.again don't forget we are enemies of the state!

I installed this and it sounds the same. Does anyone here use this? The exhaust fan noise sounds about the same.

I think I posted in this thread years ago. I still use the Panasonic whisperline fans and they still work 5 years running 24/7. These things are great. I drop mine right on top of a 6 x 16 carbon filter while cooling a 600 watt bulb and pulling fresh air into the tent. The 340 cfm 6" is what I use. Damn things work great. You can also use the weaker 240 cfm 6" for a 400 watt and a 6 x 16 filter.

the panasonic fans now come with speed controllers , some have the speed controller build it, with differant levels, others you can purchase for just over 20 bucks a really good speed controller built by panasonic for thier whisper fans

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...

Looks EXTREMELY familiar, lol. The only difference is, that I have got a 2x2x3 (metres) big area (meant for a bed or some such in studio apartments here), but with light-insulated "curtains" so that yeah - I sleep next to the "room" I've made for my garden, but I'd rather post pictures once I've got my tent I'm eager to set up once it's delivered... Nice tip, that box for the 6" inline, btw!

Can you use a speed controller on it?

 

[Final Phase]

Seven years ago I put in this exhaust fan. A very low hum can be heard from 15 feet away. Any distance from there a little sound can be heard. If the neighbors can hear it I'm sure it can't be traced back to my house unless someone comes onto the property.

The exhaust is a 9 inch fan running on ball bearings which makes it super quiet for the amount of air it's pulling through.
To complete the exhaust it's connected to a day/night thermostat.

They are SO quiet you don't need one. Keep that puppy at 100%

 

[BigDoobie]

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?
