Soundman2020 - Studio Design Forum

Figuring out the room modes has been an interesting challenge. For sure the angled non-parallel walls help reduce flutter echos and the like, and have some other beneficial acoustic properties. But they make studying the modal behaviour somewhat challenging. The bottom cuboidal portion of the room s...

I was doing some sound transmission measurements around my studio yesterday, and as a small aside decided to measure the effectiveness of this "amp riser in progress"; amp riser - small.jpg It's 1200 x 600 mm, and is a reduced version of Glenn Stanton's drum riser design. Top layer is 18mm...

And finally for this evening, some real photos and a REW file with the scans posted earlier and the estimated soffit position. There's also a sweep of the empty room done almost four years ago. It was with an uncalibrated ECM8000, and I hadn't even calibrated the volume of the sweep. I recall it bei...

Next is to address the rear wall. First off, make a deeper absorbing trap across the rear vertical portion; this one is 30cm deep; would light fluffy filling be a good choice here? rear wall bass trap.png Next get the diagonal wall and corners; the left one will need to have some kind of ventilation...

First order of business is getting these monitors into soffits. Hopefully this will directly or indirectly solve or contribute to solving many of problems 1-5. The room has a curious combination of really working for this in many ways, but against it a little bit too. The following is the culminatio...

Excellent! I'm just preparing a followup, and it's all about soffits

Cheers,

The main problems I've identified are; 1) Difference in response between left and right speakers in the frequency and time domains. No doubt the lesser treated "radiator corners" are partly responsible for this. 2) RT60 decays too quickly in highs. Room volume is 31 cubic metres (1094 cub...

The Genelec 8030a monitors are up against window as close as practical. I plan to move them out of this position, but include details and measurements for general reference. Nearfields.png The acoustic axis is a bit above ear height, but the correct ear height position didn't give as good an acousti...

Hello folks, I've been visiting several well know acoustics forums for years, and studied them and some written literature intently before designing my studio in 2015. I planned it to the best of my ability at the time and built a significant number of DIY bass traps. Those and some thinner panels f...
