Still keen for any feedback from those who've made absorption panels.
Also, in terms of sound isolation, I've been reading about resilient channels or green glue to de-couple the drywall. I can only find these as imports which are expensive and long delivery times. Anyone found something like this?
It's really helpful to have it - when I get current prices I'll write them up in this thread.
I'm setting up a music studio in 1 or 2 rooms. So early reflections, flutter echo, reverb & might use moveable panels to act as a gobo or portable vocal booth. Both rooms are small - ~ 3mx4m. Monitors...
I'm looking for the best bang for buck in setting up acoustic treatment for a charity project.
From previous threads and other users, the main options seem to be uthermo, energylite or insulboard. Densities are ~ 40,60,80 & 100 kg/m3.
This spreadsheet (thanks to @Abu)...
A better test would be the sine wave at different frequencies test (shown at 15:50 in this video: http://realtraps.com/video_demo.htm) - they showed their room to have a massive dip at 75 Hz which they were able to push up by 15dB.
I need a bunch of these for a studio I'm setting up in Manenberg, CT for a project to record local talent that I'm running next year. Will probably make them myself, but I might be interested in buying if I get busy, you've done them really nicely. Need to get hold of the budget first anyway...
