The following files form the supplementary material of our JASA 2021 paper [1].
- reflective_materials.mat : absorption profiles of commonly encountered reflective material in buildings in octave bands (.125,.25,.5,1,2,4) kHz
- wall_materials.mat : absorption profiles of commonly encountered wall materials in buildings in octave bands (.125,.25,.5,1,2,4) kHz
- floor_materials.mat : absorption profiles of commonly encountered floor materials in buildings in octave bands (.125,.25,.5,1,2,4) kHz
- ceiling_materials.mat : absorption profiles of commonly encountered ceiling materials in buildings in octave bands (.125,.25,.5,1,2,4) kHz
- materials.pdf : Readable document listing all 92 materials by category.

The .mat files can be opened using the load command in Matlab (https://fr.mathworks.com/help/matlab/ref/load.html) or the loadmat command in Python (scipy library: https://docs.scipy.org/doc/scipy/reference/generated/scipy.io.loadmat.html)

The material lists and corresponding absorption profiles were obtained by a selection of materials from the following sources:
