NEECK Validation: Acoustic Measurements and BEM Simulations

<p>This repository contains the supporting data for the paper entitled &quot;Acoustic Validation of a BEM-Suitable 3D Mesh Model of KEMAR&#39;&#39;, 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.&nbsp;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&deg; is on the left and 270&deg; is on the right. In elevation, -90&deg; is below, +90&deg; is above.&nbsp;</p> <p>---</p> <p>The data is organised as follows:</p> <p>- NEECK_HRIR_measured.sofa<br> &nbsp;&nbsp; &nbsp;(SOFA file (SimpleFreeFieldHRIR) containing the 185 acoustically measured HRIRs for the Neck-Extended Easily Computable KEMAR (NEECK))<br> - NEECK_HRTF_simulated.sofa<br> &nbsp;&nbsp; &nbsp;(SOFA file (SimpleFreeFieldTF) containing the 10,205 simulated HRTFs for the Neck-Extended Easily Computable KEMAR (NEECK))<br> - AdditionalData<br> &nbsp;&nbsp; &nbsp;(Zip folder containing data processed during the analysis stages)<br> &nbsp;&nbsp; &nbsp;- averageResponse_measured.mat<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;(mat file containing the average IR responses, corresponding inverse filters and inverse filter generation parameters)<br> &nbsp;&nbsp; &nbsp;- averageResponse_simulated.mat<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;(mat file containing the average TF responses in linear scale)<br> &nbsp;&nbsp; &nbsp;- measuredData.mat<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;(mat file containing the following data:)<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;- IRs<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;(Measured impulse responses as in SOFA file.
