This is the supplemental material for the paper:

"Bandwidths of vocal tract resonances in physical models compared to transmission-line simulations"

For the three types of physical resonators, there are the 3D-printable resonator models (in terms of STL files) and the measured volume velocity transfer functions (in terms of text files). There are also the Matlab scripts to extract the resonance frequencies and bandwidths from the transfer functions and save them as text files (comma-separated values).

The folder "Simulated-resonators" contains the area functions of the simulated vowels and the Matlab file that performs the frequency-domain simulation (either for the coarse loss model or the detailed loss model), extracts the resonance frequencies and bandwidths, and saves them to text files.

Please note that the scaling of the magnitudes of the transfer functions of the physical models may differ between the models. On a logarithmic magnitude scale (dB-scale), this translates to a individual offset for the curves, which does not affect the bandwidths (measurements).

Finally, the file "microscope-picture-of-3d-printed-tube.tif" contains a microscope image of a section of one of the 3D-printed resonators, showing the roughness of the tube walls. This roughness is a result of the layer-wise printing process, here with a layer thickness of 0.1 mm.
