Tiny All-In-One room
Posted: Sun, 2021-Jan-24, 11:45
Minor Sunday update: finished the absorptive door with 20cm of Knauf Ultracoustic insulation (≥5000 kPa.s/m²) and now (keeping in mind that the door does not isolate perfectly) the back wall is considered as an acoustic "black hole" .

Screenshots:
As expected there are only minor changes, mostly visible in the reflections diagram (ir).
Here is the comparison between the previous situation (hangers only) and the added door insulation. Some strange behaviour in the mids I believe is from the various stuff that is still in the room and should be ignored:
Not big differences but certainly listenable. Music is more "focused" and clean now, details have appeared even in very low volumes, and high volumes are now tolerable..
And now two questions:
1) Planning the final layout many different configurations have passed though my sketchup and I ended up that the safest one for my limited space is with absorbent reflection points (30cm insulation) and full absorbent ceiling (30cm insulation), see previous post. I keep reading that insulation alone will not suppress the early reflections enough end the proper way is to redirect them, something that I am unsure if I can accomplish in this room. Will I gain anything noticeable if I embed hard reflective surfaces inside the insulation on the reflection points?
2) Seeking a way to tame the 42hz standing wave I am planning on using slot resonators in the above and below soffit sections. An also ideal place for a low tuned resonator seems to be the outer part of the soffit:
will the resonator be effective being so close to the side wall insulation? How big the gap has to be? Are there other options?
Thanks,
Dio
