General Information
This data set contains CAD-Models (.skp) of the eight following Kabuki theaters: Hoo-za,
Kanamaru-za, Murakuni-za, Hakuun-za, Meiji-za, Yachiyo-za, Uchiko-za, Kaho Gekijo. The
Models include source and receiver positions used in the measurements and simulations which
are described in an accompanying article which is currently in peer review for Acta Acustica
united with Acustica. If you use this data set please cite the reference, which will be given in
DepositOnce under related documents, as soon as the article will have appeared.

Data description
The room models were created using the Software SketchUp Make 20171. This version of the
software is needed to view the models. The models are based on existing drawings and distan-
ce measurements obtained during in-situ measurements described in the aforementioned paper.
For the Meiji-za, the Hakuun-za, the Uchiko-za, and the Kanamaru-za, plans and section cuts
exported from laser scans2obtain in the rooms could be used to verify the drawings.

In all rooms, the absorption coefficients displayed in table 1 were applied to the respective
surfaces. In the Yachiyo-za, the Murakuni-za, the Kaho-Gekijo and the Hoo-za, the stagehouse
was not completely included in all models but cut off at the point of the visible stage sets and a
constant absorption coefficient of = 0.8 was assigned to the boundary surfaces.

To all other surfaces, the residual absorption coefficients shown in table 2 were applied, which
are the result of adjusting the simulated reverberation times to match the measured reverberation
times within the JND mentioned in ISO 3382 (rel. 5%).

The simulation were carried out, using the software Odeon 11.23 Combined. In the software,
the specified scattering at 707 Hz are extrapolated to a frequency function of rising scattering
values increasing with frequency. For the occupied audience areas (Tatami, occupied), a scatte-
ring coefficient at 707 Hz of 0.7 has been applied. For all other surfaces, a value of 0.5 has been
used.
