Porous Absorber Calculator

An acoustic absorption calculator to help in the design of rooms in which acoustic accuracy is important, such as a home cinema or a recording studio.

The Porous Absorber Calculator uses WebAssembly (compiled from Rust), to create an absoprtion curve of a particular thickness of porous absorber layer (such as glass fibre or Rockwool) mounted either directly against a wall, or with an air gap between the wall and the porous layer.

• The equations used to calculate these absorption curves are taken from the first edition of the book "Acoustic Absorbers and Diffusers" by Trevor Cox and Peter D'Antonio (now in its third edition)
