I am aware of very good cathedral ceilings as sound rooms, but the speaker are oriented 90 degrees to yours ie they aim down the ridge, not across it.
nzlowie Posted November 10, 2019 Author Posted November 10, 2019 Ceiling decided..... Gyprock but not completely flat, compromise with existing structure. Just need to frame up 2 walls then we can start insulation and lining. Next have to decide on lighting, was thinking of 6 downlights for full lighting if required and maybe 2 low wattage wall lights down each side on a separate circuit for darker times. Photo is of one side wall. 2
Andrews_melb Posted November 10, 2019 Posted November 10, 2019 Nice work, Will look good. Its a conventional roof not a truss roof - as its its been built by hand on site compared to roof trusses.
nzlowie Posted December 23, 2019 Author Posted December 23, 2019 Just about ready for paint and was thinking about making front wall a feature. Vertical timber slats or batterns sort of like this feature wall. Your thoughts?

Vertical timber slats in a 1D BAD pattern would look cool and provide diffusion and fairly simple to DIY...but more important than feature walls, what are you planning to do with the brick walls? You should consider furring channel and gyprock with insulation behind otherwise you'll never get the bass under control. The gyprock walls (and ceiling) provide "compliance" to the room soaking up low bass. mike

The walls ended up with a 6" cavity filled with insulation. That end wall is where I'm thinking of doing the feature, will also help hide the pillar we had to leave just off center. 1
nzlowie Posted January 3, 2020 Author Posted January 3, 2020 Almost there..... Waiting on the sparkie and carpet. Thinking about the placement of the absorbtion panels, or should I wait till everything is set up? Think bass should be under control due to compliance of the wall, so really thinking about slap or flutter echo (or whatever it's called!) I've read that we should have absorbtion at the first reflection point, correct? Have also been told by a professional acustic designer to install detraction type defusers in line with our ears. Your thoughts.... Cheers and happy New year to all! 1
almikel Posted January 4, 2020 Posted January 4, 2020 Happy new year - you have the basis of a fantastic room! 19 hours ago, nzlowie said: Thinking about the placement of the absorbtion panels, or should I wait till everything is set up? yes - and measure before you do anything 19 hours ago, nzlowie said: Think bass should be under control You won't know till you measure, but your reverb times <150Hz will be much better than they would have been with rigid walls. I would still expect that some broadband absorption targeting the lower end (ie placed straddling corners as big and deep as practical) will help cleaning up below 250Hz or so. 20 hours ago, nzlowie said: I've read that we should have absorption at the first reflection point, correct? That's a contentious point - Toole says no, if you have main speakers with a smooth (but falling) off axis frequency response - you want the 1st reflections to have the same frequency content as the direct sound - which won't happen with absorption at 1st reflection points, as the absorption will absorb more treble than bass. I don't know what the FR of your Azura horns are off axis, but being horns (and more directive), I wouldn't be placing absorption at 1st reflection points yet...if at all. I would focus on getting the room's bass response right 1st with broadband absorption straddling corners, which keeps a reasonable amount of wall surfaces bare to bounce treble around so the room doesn't become too dead too fast. IME with a lightly constructed room, specialist bass traps (membrane, helmholtz etc) aren't required with a few bands of EQ cut below 150Hz or so to manage the bass that the absorption is too small to manage. 20 hours ago, nzlowie said: Have also been told by a professional acoustic designer to install detraction type diffusers in line with our ears. Your thoughts.... Agreed that diffusers are often deployed in line with your ears. I regard diffusers as a significant "step up" in room treatment beyond simple absorption - well applied they work brilliantly - but they don't assist with getting the bass under control, which IMHO needs to happen first. Once the room's bass is under control, diffusion can be applied to bring back treble into the room, as possibly on the path to getting the bass under control, the absorption has soaked up too much treble - an example being applying slats over the absorption in a 1D BAD pattern which will reflect/diffuse higher frequencies, but still absorb bass. Keep in mind that diffusers have a "minimum seating distance" - for high end diffusers such as Quadratic Residue Diffusers (QRDs), this is 3 x the lowest frequency diffused...but this distance could be relaxed for BAD panels which don't diffuse as much as QRDs. IMHO, a 1D BAD slat panel over absorption makes for an interesting "feature" in the room - I posted a picture above. cheers Mike 1

Behind the listen chair is a 4.5mtr sliding door (double glazed) so that has a heavy acoustic curtain covering it which means we loose a full wall for art or whatever. Originally it was just going to be my music room, but as its come up so good it might get commandeered! 1
