looking good!

for free - the SU free via the web seems pretty decent. all the tools are there. can't use dynamic components as dynamic (i imported one of mine and tried to scale it, but no joy on the dynamic auto-layout functions) but all the regular grouping and component create work. so if someone is interested...

i bought the pro subscription. $200/yr. has SU and LayOut. been using it for years on the old pro license under the education price (since i was getting my masters degree...) the latest version is pretty good in terms of stability and updated functionality. i'm mainly using the dynamic components fu...

i've updated my broadband absorption SU component. you've probably seen it in many designs and possibly used it before. anyways it's updated to function better. https://3dwarehouse.sketchup.com/model/ed05d58a-f296-4fbc-8b74-5b5175c121d8/Broadband-Absorption-Assembly-aka-Hangers and i've updated the ...

looks great! overall very nice workmanship!

mmm i love the web site with all the crazy claims. me luv's some snake oil in the morning :mrgreen: my concerns: fake test results shown without actual references... fire rating - burn thru reduces fire rating on the wall? installers - getting it wrong... imagine rippling walls... or shorting out th...

interesting thoughts - you need attenuation of machine noise (preferably before-or-as it exits the utility closet) and you need to reduce flow velocity, avoid duct induced noises, attenuate noises external to the duct (hence the "put something around it") and then once you penetrate the sp...

the one fan approach really only functions in a small number of cases, e.g. a small booth exchanging air with a larger ventilated space. whereas a forced air system is closed, so only a single (albeit large) blower for air movement, with balanced ducting and dampers, plus an outdoor ventilation (ERV...

you are using two fans now? one on intake and one on exhaust? if not...

so the silencers that i saw were "straight through" which implies the absorption panels in the flow and around the shell to provide absorption. i have no other details on their internals. i do know the ducts where about 1m in diameter in the big room, perhaps larger. the secret to all of t...

the Galaxy studio in BE - had silencers the size of cars on the shell of the big room, and most of the others were the size of refrigerators (the ultimate goal according to Eric was to get the speed down to 1m/sec). you're not getting sufficient room exchange in large rooms without big ducts @ low f...

used in stepped seals (bank vault) style stops.

it might help to reach out to auto supply stores and see if they carry something which is more rubber and less foam.

i remember finding some rubber seal on Amazon for a client in the EU, i'll see if i can find the link again but maybe a search in your local Amazon site will reveal something useful. "rubber automobile trunk seal" Or perhaps "rubber automobile boot seal"

maybe consider inside-out walls for the interior room - this way your walls and ceiling are already absorptive all around. then add diffusers and slat panels as needed to reinforce high frequency response as needed. to prevent people indenting the walls, use a heavy wire mesh under the cloth treatme...

one consideration is building a membrane trap on the center of the back wall to reduce the modal response. maybe start with a MLV type which would be broader band as it's not really tuned, but rather would help to disrupt the pressure. a matching one on the front wall may be needed as well. somethin...
