Acoustic / Insulated Ducting for Noise Control

Hi guys, I have a 3x3x6 DR90 II Secret Jardin Tent. I plan on ordering a 6'' TD150-S silent fan and carbon filter from amazon. I heard the unit itself was very quiet but the shuffling of all the air is the big noise maker.

My question to you guys is, have any of you used Acoustic Ducting / Insulated Ducting for this purpose?

The filter and fan will reside in the tent.

Is the fiberglass contained in the ducting dangerous to either me or the plants??

Sound is a big issue for me, as I sleep in the room in an apartment and another bedroom is right downstairs below me.

Duct liner will indeed work , but these are some things to consider when using duct liner for acoustical purposes, first you will have to increase your duct size to accomadate the thickness you use , I would use 1 inch thick liner for this pupose so if you were running 6'' round you will have to increase to 8inch round , second would be dust control ,and humidity control ,then also remember duct liner will absorb smell to a certain point.in the long run you might want to look in to a ventalation Sound Trap device .

Check out this page of a previous thread: https://www.rollitup.org/indoor-growing/122532-quiet-neighbors-can-hear-you-42.html scroll down for pics of my filter+fan+ducting. And the "softbox" tip.

I use (a brand or type called) "sonodeck" which makes a major difference by itself.

I wrap my shit in cheap heavy sleeping bags (fan and ducting) and its quieter in my bed room than when I turn on our oscillating fan. Food for thought.-S0uP

Thanks much guys, this information helps immensely

maybe use rubberized spray paint and get the insides of the pipes w/ it? and use rubber mounting clips!
and of course a muffler for the inline fan

i use the acoustic ducting, the green stuff, pretty cheap, it works really well, i think its worth the money

Using insulated ducting too (a regular alu 125mm wrapped in some 1" thick rockwool, all wrapped in a very thing layer of alu/plastic to hold it all) between carbonfilter/fan/exhaust and it does pretty well.
To counter the airflow noise issue, you can also add a silencer like a muffler at the end of your ducting lince, it really does help!
