Hello friends,


Full disclosure. It feels good to be back on GDIY! My family and I I hope you are well in these surreal times. This build is a hybrid QRD and Ramped QRD design with low frequency treatments.  Acoustic Engineering is more complicated then I can convey and we  have been working on the look-book for several years as a starting point for Martin and the team at Pilchner Schoustal, Hopefully this thread can help us decide on some options.


Since this is our first post in some months we should fill GDIY in on our progress. For starters we are still building out cards for our console and still ordering parts. More on that soon.

On a side not, we have had 2 garbage bins dropped/filled with a last bin coming in a few days all in preparation for re-modelling our farmhouse. With lumber long stored in the Barn we are eager to start building and hope to gather insight from GDIY in regards to carpentry, materials, build techniques etc. 


We've attached the basic layout of the room we are developing first. A 16.5 x 14.5 x 9-9.5  room. The Schroeder Diffusor or Quadratic Residue Diffuser that we are building is an instillation rather then what we know as a typical QRD Panel. We say installation as the "Walls" will include LF absorption and... well.. it is a 14.5 x 9 foot wall. Its a lot of real estate to cover in timber.


I am going to do my best to be thorough in this thread.

 

Couple notes on the room.

  • The floor is maple hardwood and slopes from 9 feet to 9 1/2 feet giving us a "natural" offset with the ceiling.
  • There is a 8.25 foot "open concept" nook that leads into the fireplace lounge and kitchen.
  • There is a 9 inch trim around the base walls of room.
  • ?Slat & Plaster? walls (building over)


CARPENTRY


While we are fortunate to have the tools, materials and space to build this installation, there are so many techniques that experienced carpenters can impart we simply will not consider. We hope to implement some clever carpentry into our QRD walls. Storage space being important as well as Sunlight. That said building sliding QRD doors or hidden cupboard styled doors that cover that windows is of importance.


MATERIALS


We are interested to learn more about materials used in Sound Absorption. My partner asked if we can make a couch and is interested in learning about the acoustic properties of furniture foam.


BUILD TECHNIQUES


We have been taking in the many unique QRD builds on youtube. We are hoping to figure out how to create a seamless look for the Ramped QRD on the ceiling and QRD Wall.


Thank you for reading this and please ask any questions you might have,


Be well,


Wall
