cyberkank Posted August 23, 2018 Share Posted August 23, 2018 Hi, Looking at putting some diffusion/absorbtion panel on my ceiling (white) to minimize first order reflection. I was thinking of the one that slightly hang down creating a gap between the actual ceiling and the acoustic panel and then I can potentially put some LED inside to have some ambient light. I see some example photos on google, but not sure where they are available in Australia (SA in particular) Does anyone know where I can get my hand on some, size is about 2.4m to 1.2m. Also open to other ideas and seeing if there are any other suggestions on ceiling acoustic treatments (must be wife friendly). Link to comment Share on other sites More sharing options...

almikel Posted August 23, 2018 Share Posted August 23, 2018 DIY or purchased?If you want diffusion & absorption then Binary Amplitude Diffusion (BAD) panels do both.In studio terminology having a panel hang from the ceiling with a gap is called a “Cloud”BAD panels come in 1D and 2D.1D is easy to DIY - basically slats with random gaps over absorption 2D is harder and requires a mask with holes over the absorption.I think they look great but SWMBO may not Mike Link to comment Share on other sites More sharing options...

Depending on complexity, cost and overall look. yeah, my intention was to have the "cloud" ceiling so I can install some ambient lights using LED on the ceiling.

Guest Peter the Greek Posted August 23, 2018 Share Posted August 23, 2018 Acoustic Vision will sell you a BAD that size. Either the RPG product or the QuestAI product. Easy to hang like you suggest. Or perhaps a cluster of RPG BAD Arc's How high is the ceiling? I am a particular fan of RPG's waveform which uses their flutter free diffuser as slats and absorption behind. We had drawings done up for our last room but changed our minds (reasons I wont bore you with) Link to comment Share on other sites More sharing options...

Darren69 Posted August 24, 2018 Share Posted August 24, 2018 Whatever way you go, first reflection absorption on the ceiling is an excellent bang-for-buck mod, it worked really well in my room. Link to comment Share on other sites More sharing options...

cyberkank Posted August 24, 2018 Author Share Posted August 24, 2018 Crap, looks like the retailer is not recommending a single panel to be mounted due to weight (40kg). Might have to consider multiple panels option. Link to comment Share on other sites More sharing options...
Guest Peter the Greek Posted August 24, 2018 Share Posted August 24, 2018 This is a RPG BAD: The sections with the holes below is Qperf. The panel below is what I used for first wall reflections 5 minutes ago, cyberkank said: 1 hour ago, Darren69 said: Whatever way you go, first reflection absorption on the ceiling is an excellent bang-for-buck mod, it worked really well in my room. Yes. Likely to pull the trigger on a large BAD panel. Just need to confirm sizing and installation accessories Ask for a comparison with the QPerf. Its the same concept, but the hole pattern is punched into the fiberglass as opposed to a membrane, so you get better mid range absorption, plus all the benefits of the diffusion Link to comment Share on other sites More sharing options...

Just put cleats into the rafters, drop some chain down, cleats into the panel. Presto. Unless of course they build a flimsy panel Edited August 24, 2018 by Peter the Greek Link to comment Share on other sites More sharing options...
davewantsmoore Posted August 24, 2018 Share Posted August 24, 2018 40KG not a huge static weight if used solid mountings. I don't know how heavy my ceiling baffle was (heaps! more than that - at least 100kg) ... but it's hanging from just 4x eye-screws (decent sized ones, screwed into beams though).

Darren69 Posted August 24, 2018 Share Posted August 24, 2018 My absorbers would have to be 30-40kg each, I screwed through to the ceiling batons. Six screws in each I think, no probs. Link to comment Share on other sites More sharing options...

Most of the effort would be in making it look good. Achieving diffusion on the ceiling is a worthwhile goal, which is where BAD panels come in - absorption and diffusion...but any treatment on the ceiling is better than none...

Hipper Posted August 24, 2018 Share Posted August 24, 2018 I would not buy anything yet until you can establish for sure that the ceiling treatment will make a difference. I don't know what your speakers are but different types have different ways the sound fans out. For instance the ribbon tweeters on my speakers spread about thirty degrees vertically which means in my case there are no ceiling reflections. I tested this and it is true. You could get this information from your speaker makers. If you can you should try and put something up on the ceiling for one (or both) speakers so that any reflections are absorbed and then listen for any difference. You could use say a folded duvet jammed up there with a 'T' shaped piece of wood. Another way would be to put something absorbent above the front of the speaker so it would prevent the sound going up to the ceiling. If your tests do show ceiling reflections these will be from around 250Hz upwards (the approximate Schroeder frequency for your room). Therefore you would want some product that works in that range. When looking at panels etc. you should check what frequencies they absorb or diffuse. Sound proofing products like the one you linked probably won't be suitable. Here in the UK we have GIK: http://gikacoustics.co.uk/product/gik-acoustics-242-acoustic-panel/ The 242 panel linked would be suitable and can be 'cloud mounted' as they call it. You can click the 'Test Results' link to see what it absorbs. You can also see they weigh two or four kilograms each. I would think an absorbent panel more likely is better then diffusion as you may sit too close to the panel (diffusors, depending on the type, need a certain distance to work properly). You wouldn't need to cover a large area, just the point the reflections occur - a two foot square panel would surely suffice. 2 Link to comment Share on other sites More sharing options...

lowpoke Posted August 30, 2018 Share Posted August 30, 2018 (edited) I'm a little late to the party on this one, but if you're interested I can put you in touch with a local craftsman who has just made some clouds and diffusers for a local sound engineer's home studio. Here's a pic. Clouds can be seen above the diffuser. Snd me a PM if you want his contact info. Edited August 30, 2018 by lowpoke 2 Link to comment Share on other sites More sharing options...
