Reverberation time T15 across octave bands (125 to 4000 Hz) for various configurations. The “Initial” shows the T15 for the original configuration. The minimum and maximum values reflect the modeled acoustic extremes for absorption. The “10% scattering” and “99% scattering” lines show the T15 results for the initial model with the scattering set to these values. “Measurement” refers to the measured values, with +/−0.1 s envelopes indicating uncertainty bounds.
