3- "intro": "Each section varies one property of the simulated sheet or of the excitation while everything else stays at the simulator defaults: a 12 by 18 inch, 22 gauge (0.79 mm) stainless steel sheet with a 3 mm bow across its width, heard 1 m in front of its center, recorded for 4 s. Click a player to hear a clip. Within a section the clips share one playback gain, so the loudness differences you hear are the ones the model predicts; between sections the gain differs. The numbers under each clip are the peak pressure and sound pressure level at the listener, the RMS pressure over the clip, the spectral centroid of the sound between 0.2 and 1.2 s (a measure of brightness), and fitted 60 dB decay times of a low and a high band. 'Open in simulator' runs the same case interactively.",

The clips are computed on a 4 mm grid (the interactive app defaults to 8 mm for speed; the 'Open in simulator' links carry the 4 mm setting, so they reproduce the clip exactly but run slower).
