congrats! and looking back at the photos - damn! those are some straight wires! although i do recommend leaving some slack when crossing isolation boundaries to ensure minimal coupling from tight wire tension.

it probably doesn't matter M or P -- although keep in mind they're running 100% of time your rooms are occupied... so check for continuous operation specs. why 4 per room? why not 2? supply and return. you only need the attenuator at the interior junction. then route via soffit ducting in the room. ...

i would also factor into the equation using the space above the bathroom / kitchen for the hvac equipment unless you can put it into the new garage. fresh air will be needed :-) and i'd try to go with a full 4.2m on the outside wall with a truss roof frame. and 3.8m ceiling on the inside of the stud...

i did ask the engineer the air question - and the response was - air is not desirable. :-) but somehow in their testing, the random smearing of the GG produced better results in their lab testing. counterintuitive at best as air pockets could cause resonances between the mass layers (very high frequ...

on the duct size - if you use 16" duct, then expand into a 24"x24" soffit plenum and 24" flex if routing, then you'll have a 3:1 on the plenum or 2.25:1 on the duct so basically a 2x-3x speed reduction in the room. so even if you went with a 12" duct in the ceiling w. 20x20 ...

if you need more than 300cfm for both, then go with two ERV units. otherwise, and presuming you'll have the two systems linked anyways due to equalising the pressure across rooms etc, then a single unit should be ok. make sure that you have easy access to the filters etc on the units because you'll ...

agree on the multiple layers of GG vs single layer. also - one of the weird things about GG - you need to use the caulk gun approach to putting it onto the surface vs using a trowel. in talking with the GG engineers, the even trowel spread (like when tiling for example) is LESS effective than using ...

i think Stuart uses the server for other projects (rendering etc) which can increase the load, but also this forum software has some limitations and thats why you see the db issues and/or corrupt files. certainly bot scales can impact the site but you can also restrict the common ones fairly easily ...

basically you need a pathway through the attenuator which approximates the area of the duct in. so let's say you have a 1ft2 duct, then your pathway should be 1ft2. then if you have 3 dividers, your minimal length of an attenuator is likely to be 60" L x 30" W x 18" D or so when you f...

i usually spec the M series: https://www.mitsubishicomfort.com/commercial/products/m-series-indoor?modelID=SVZ for in-room, i been spec'ing the cassette unit mounted into the soffit - works nicely. for computer closets - the floor mount unit is useful for cooling the server racks. and the ductless u...

i haven't used LG for studios. typically i use Mitsubishi most times, or whatever the local contractor can get. i just (myself) got a full blown Trane system installed for the house - it's fully variable speed compressor and air handler (whereas most times i spec a two stage compressor and variable ...

since the ceiling is solid overhead - i'd route the ducts in the trusses and drop through on the edges into in-room silencers and in-soffit ducts and plenums on the vents. you have plenty of ceiling height and the soffits up on the wall-ceiling junction will help with absorption as well as the ducti...

his drawings are done using Sketchup. there is a free web based version as well as (pricey) paid versions. the main differences are: the pro (or studio) version can run on the desktop (PC or Mac) and support "extensions" (Ruby based scripts which do many things) and "dynamic component...

cloud versus simply mounting absorption on the ceiling will be more a function of ceiling height and any significant modal issues for your listening spot. regardless you will to use ICW light boxes or equiv when you have lights in contact with insulation - even LED lights can run hot.

essentially, the overlap can be minimal - say 1" depth of the duct board/liner. commercial units are usually straight through with absorption liner and/or mesh - but designed for mechanical system noise reduction more than inter-room noise attenuation. still, the staggered approach is generally...
