it will still do it's job in your case, but generally, for small systems, as long as it's not foil covered, or is perforated foil, it should be ok as a sealed surface on it could reduce its effectiveness at absorption - whereas in large systems you might want large runs to have the foil to reduce fr...

cheers!

yes it will make a difference for the better -- with the caveat that fans make noise - mechanical and air noise. so keep them on the far side of the silencers is key - but also consider maintenance - cleaning, replacement etc. the main reason i recommend ERV/HRV units - powerful air flow, configurab...

yes, you can definitely do the REW measurements and pretty sure you make some analysis

if i was going to shorten it, i would go with 4.75m - 4.875m on the length as that will be a smoother distribution and overall metrics which are beneficial.

yeppers - all of the remaining space is filled. sometimes i layer with 1-2" of semi-rigid (e.g. 703) inside the frame faces, then a layer of MLV, and interior filled with lightweight batts. but sometimes it's too small or costly so i just do the lightweight, cover with cloth, and then add slats...

Yes your air velocity into the silence can be faster speed and then through expansion, slow down, before exiting the low noise vent.

yes, definitely try to set the fan speed with the least amount of possible electronics noise. this way after a session is done and some more air is needed, just crank it. :-) same with lighting - having work lights to see what you're doing during set up / tear down and general maintenance, and then ...

the silencer and plenums can all be in the room :-) when i'm designing, i typically use wall-ceiling soffits to allow me to route air, wires, lighting etc PLUS get a lot more absorption while freeing up the walls and floor spaces. here's an example of a silencer in the soffit feeding a plenum center...

no, i'd keep the longer room 7.2m as-is. the thing you will want to work on is the RT60 (or whatever it really is in a small room) and that can be via scattered absorption placement as well as the usual first reflection points, back wall, heavy drapes as needed etc. to get the room balanced.

typically the listening seating is some form of couch - which is a bass trap :-) and the modal distribution in a room doesn't usually favor that location if the primary listening position is the front of the room. as far as improving the LF response in the back of the room - an addition subwoofer tu...

i would go with the longer room - you can see in the Benollo scale how much more even the mode distribution is per octave. then presuming the windows wall is the lower part of the pitch, i'd face that wall centered between the two windows.

quieter is betterer :-) the thing about quieter though, is when things are quieter, you can hear more noises :-) you might measure ~1m from the vent openings on the plenum just to get the level at the opening. as you build out the soffit, with absorption etc, then you may find it reduces a bit more ...

your silencer does not have to be the plenum. you could create the silencer effectively with the same area of the duct, then expand into a plenum to get the velocity reduction. you could also create the silencer to vent in both sides to plenums there to make the air flow symmetrical around your desk.
