Neeck Validation: Acoustic Measurements And Bem Simulations

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. 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. --- The data is organised as follows: - NEECK_HRIR_measured.sofa<br> (SOFA file (SimpleFreeFieldHRIR) containing the 185 acoustically measured HRIRs for the Neck-Extended Easily Computable KEMAR (NEECK))<br> - NEECK_HRTF_simulated.sofa<br> (SOFA file (SimpleFreeFieldTF) containing the 10,205 simulated HRTFs for the Neck-Extended Easily Computable KEMAR (NEECK))<br> - AdditionalData<br> (Zip folder containing data processed during the analysis stages)<br> - averageResponse_measured.mat<br> (mat file containing the average IR responses, corresponding inverse filters and inverse filter generation parameters)<br> - averageResponse_simulated.mat<br> (mat file containing the average TF responses in linear scale)<br> - measuredData.mat<br> (mat file containing the following data:)<br> - IRs<br> (Measured impulse responses as in SOFA file.
