I’m struggling to determine the amount and type of treatments to build for a small rehearsal space.
I’ve bought the All In One DIY Acoustic Treatment Build Plans Package from Acoustic Fields and can construct from that.
Tools such as AMROC give a general idea, and I’ve found tables of the acoustic properties of different building materials.
Dennis’ consultation suggested 16 CPs placed around the room, but (aside from unaffordable) this wouldn’t leave much space for instruments.
Is there software or an online tool that would let me account for the specific room materials?
i.e. one wall is mostly window and door with glass panels ( according to Dennis “Standard windows are the perfect low frequency absorber …” ),
another wall has 2′ solid grout filled CMU at the bottom with solid earth behind, and timber frame above with a CMU wall 12″ behind that.
The other planes (two walls, ceiling, floor) are yet to be built and could incorporate the Carbon or other absorption /diffusion technology etc, but how many square feet and which kind of treatment do I need?
I can’t afford an acoustic engineer on top of all the materials but I’m happy to do the assessment, buy the materials and do the work myself. Minor adjustment of reflective surfaces could be done after the build.

We can assist you with the design process and you can build the design. All of our designs include DIY build plans . There are two parts to our design services. We have noise transmission and treatment which includes the absorption and diffusion requirements with the in room energy.
