Got the baffle boxes on the outer leaf in place too: IMG-20251213-WA0006.jpg IMG-20251213-WA0010.jpg IMG-20251213-WA0005.jpg IMG-20251213-WA0009.jpg Which duct will be better to connect the boxes? The (more rigid) Aerofoam duct: IMG-20251213-WA0008.jpg or the flexduct? IMG-20251213-WA0011.jpg I'm pr...

Thanks Glenn. Making things like that jig still saved me some time (or I'd just like to think that) I had to make 8 pieces of duct liner in that shape for the 4 boxes. I also made some router templates for the door hinges (one for the doors and one for the jambs) and that probably took longer than j...

Seeing this thread has quite a few views (real people or bots?). I thought it might be usefull for others to see how I built my baffle box: Made them from MDF and designed them to be around twice the size of the round 125mm duct. It sticks out 6 cm from the ceiling and I will cover this up with a ce...

That looks awesome and a big thanks for sharing your build.

Excellent build and great you share a lot of photo's

If I use 125 mm round duct for my ventilation and go to 16 x 16 cm square inside the baffle box, which is roughly twice the size, my attenuator/silencer/baffle box :D will be 93 x 40,5 x 25 cm. This is with 3 baffles inside the box. I can't go bigger due to restricted space between the joists. Will ...

Thanks! I don't think I'll have the space for a plenum; the dimmensions of my room are 4,5 x 3 x 2,2 m within the inner leaf. I'll try my luck with the 4 silencer boxes and if it's too noisy, I can add a plenum later on. It'll be most of all a practise room and the recording I'm doing (if any) is in...

Do you have a picture of such a plenum? I think I understand what you mean but want to be sure.

Thanks Gullfo, sounds reasonable to me. It's just that Eric Desart was quite the authority on sound isolation. The sound passing straight through might be reduced by the narrow exhaust, he's talking about. Maybe I'll find time to build 2 micro silencer boxes from scrap wood and measure the differenc...

I'm doing a garage-to-band-practise-room conversion. This, after years of exploring my needs/options and I think I'm all good; Concrete slab, mass-spring-mass, mini split unit aircon. Since my external leaf is almost finished (double sheets of 18 mm osb all walls and ceiling) and nearly ready for th...
