Demonstrative tool for building acoustics. From volume, total surface and the surface inventory (material + per-band α from the library, editable) it computes the reverberation time T60 over the 6 octave bands 125–4000 Hz with the three classic formulations — Sabine, Eyring, Millington — plus air absorption (ISO 9613-1, optional). Table output, T60-vs-frequency chart and a summary card. A pure calculator: no regulatory comparison.
