4/18/2023 0 Comments Fuzzmeasure![]() ![]() The problem is, the flutter doesn't seem to be associated with ANY of your dimensions! Apparently, it's associated with a distance of about 2.5m, (or maybe 5m, or maybe 1.25 m), but that doesn't fit the room dimensions that you mentioned. sort of.)įor your flutter echo, a few inches of porous absorption on the offending surfaces should do the trick. you could play it safe and do all three at once! (Just kidding. There's pros and cons regarding all three approaches. If you prefer perf panel, then Andre is probably the best expert around on that. If you prefer slats/slot walls, then take a look at the John Sayers forum (he loves slot walls). small home studio rooms, but if you ignore that and stick to just the technical details of "how" and "why", you'll be fine. It's long, and there's a bit of "mine is bigger than yours" opinions and back-and-forth arguing regarding treatment of large pro rooms vs. It's not as easy as some people would like you to think. In both cases, tuning that low accurately is a challenge. You basically have two choices here: 1) Very deep Helmholtz resonators, such as slots or perforated panel. What soffit traps do you have in there? How are they tuned? The Soffit traps are supposed to be effective down to 40Hz, but that a lot of energy to absorb when I look at the waterfall! I don't think any of my panels have any effect in that range. The second harmonic of that axial width (0.2.0) is showing up quite well at around 96 Hz.Ĭonclusion: You need a stack of deep bass trapping! Which I think you already knew. Perhaps there was some object in the room, close to the left speaker, that has a natural resonance at 41.9 Hz? Maybe you could post pictures of the room exactly as it was when you took those measurements. It's also much larger on the left speaker and hardly there at all on the right, so I'd guess it is something physical in the room that is resonating, not a room mode. However, the second big peak is 41.9 Hz in REW, but your second axial mode (0.1.0, width) is predicted to be at 48.4 Hz., so that doesn't match at all. which is length) at 36.2 Hz, Looks like a very close match to the actual results! I'm seeing the first huge peak at 35.8 Hz in REW, which is basically a direct match. In your first post, you said: "My room is 3,56m wide, 4,76m long, 2,76m high.". (I'll also use Sonarworks once I'm happy with the treatment results).Īny idea on how to treat the big decay from 30Hz to 50Hz?Those are resonances, not decays. Maybe everything is normal and I just need to go ahead and hang all my acoustic panels, play with speaker placement and call it a day. I did all my measures with my duet (2008), maybe it's faulty (I calibrated it in REW, but not in Fuzzmeasure). But not all of them appear in REW (100hz for example). I get weird ringings around 35Hz, 100 and at 15k that seem to go on forever. ![]() Second problem is the waterfall in Fuzzmeasure. The fuzzmeasure one seems more coherent in my experience. The REW one seems all twisted, with a big bump in the midrange, and a big large dip in the highs. The first problem is the in the Frequency Response differences between the two softwares. ![]() I get a nasty metallic ringing when I clap my hands at the listening spot, so that confirms it. This means the clouds and wall/ceilings panels are not doing their job yet, hence the big mess in the highs in my measurements (as expected). But they are not hanging on the walls yet, just resting on the floor. I put my acoustic panel at the first reflections spots and big corners (6 GIK panels, 3 Soffit panels, 6 diy panels). I put the mic at 38% of the length from the front wall (figured I'd start here and move the speakers first) My speakers are almost touching the front wall (see beautiful sketch I did) Maybe you guys can help me make sense of it? I just moved to a new room and I get different measurements when I use Fuzzmeasure and REW. ![]()
