<p>This repository contains the supporting data for the paper entitled "Acoustic Validation of a BEM-Suitable 3D Mesh Model of KEMAR'', K. Young, G. Kearney, and A. I. Tew, at the 2018 AES International Conference on Spatial Reproduction - Aesthetics and Science, Tokyo. Available at: http://www.aes.org/e-lib/browse.cfm?elib=19662. Please cite both the paper and dataset if used.</p>
<p>Note: the azimuth angle system used in this work increments positively in the left direction, such that 90° is on the left and 270° is on the right. In elevation, -90° is below, +90° is above. </p>
