Abstract

Dataset for A Compact Two-Loudspeaker Virtual Sound Reproduction System for Clinical Testing of Spatial Hearing With Hearing-Assistive Devices Dataset DOI: https://doi.org/10.5258/SOTON/D2081 Authors: Eric Hamdan & Mark Fletcher, Auditory Implant Service, University of Southampton This dataset supports the publication: AUTHORS: Eric Hamdan and Mark Fletcher TITLE: A Compact Two-Loudspeaker Virtual Sound Reproduction System for Clinical Testing of Spatial Hearing With Hearing-Assistive Devices JOURNAL: Frontiers in Neuroscience This dataset contains CSV files for each figure in the manuscript that has graphed data, i.e., Figures 4 - 15. The CSV files contain the x,y data for each graph (some graphs have multiple dependent variables, e.g., y1, y2, etc.). There is a folder for each figure which contains the corresponding CVS file, e.g., Figure5/Figure_5.csv For figures with subfigures, i.e., (A), (B), etc., there is a CSV file for each subfigure, e.g., Figure7/Figure_7A.csv Figure7/Figure_7B.csv Figures 14A,B and 15A,B feature 2D graphs, i.e., color maps. The two independent variables are head rotation angle (degrees) and frequency (Hz). For these subfigures, there is a CSV file for each head rotation angle, e.g., Figure15/Figure_15A_Angle-10.csv -> corresponds to a head rotation angle of -10 degrees . . . Figure15/Figure_15A_Angle00.csv -> corresponds to a head rotation angle of 0 degrees . . . Figure15/Figure_15A_Angle10.csv -> corresponds to a head rotation angle of 10 degrees Additionally, the folders LAC_AE/ and Booth_AE/ contain the CSV files for the smoothed absolute error (AE) associated with Figures 14 and 15 (corresponding to the large anechoic chamber (LAC) and the audiological booth). There is a CSV file for the AE calculated for each head rotation angle (as done with Figures 14A,B and 15A,B), and with and without filter compensation for the head rotation. CSV files for data with head rotation compensation are denoted with "LACC" or "BC". CSV files for data with no head rotation compensation are denoted with "LACNC" and "BNC", e.g. LAC_AE/LACC_AEhat_Angle00.csv -> corresponds to a head rotation angle of 0 degrees, in the LAC, with head rotation compensation LAC_AE/LACNC_AEhat_Angle00.csv -> corresponds to a head rotation angle of 0 degrees, in the LAC, no head rotation compensation Booth_AE/BC_AEhat_Angle00.csv -> corresponds to a head rotation angle of 0 degrees, in the booth, with head rotation compensation Booth_AE/BNC_AEhat_Angle00.csv -> corresponds to a head rotation angle of 0 degrees, in the booth, no head rotation compensation Finally, there are stereo HAD recordings of a target speech recording played from each of the six loudspeakers used in the experiment (L3, L2, L1, R1, R2, R3) and recordings of the VA system (L1 and R1) attempting to reproduce the target signal, as detailed in section Results->Stationary Measurements of the manuscript. Recordings were made in the LAC and audiological booth. The LAC and booth recordings are in the folders HAD_Recordings/LAC and HAD_Recordings/Booth, respectively. The target recordings are denoted with the letter 'd' and the reproduced recordings are denoted with the letter 'p', e.g., HAD_Recordings/LAC/LAC_d_L1.wav -> recording of the target speech played from loudspeaker L1 in the LAC HAD_Recordings/LAC/LAC_p_L1.wav -> recording of the VA system reproduced speech played from loudspeaker L1 in the LAC HAD_Recordings/Booth/Booth_d_L1.wav -> recording of the target speech played from loudspeaker L1 in the audiological booth HAD_Recordings/Booth/Booth_p_L1.wav -> recording of the VA system reproduced speech played from loudspeaker L1 in the audiological booth Date of data collection: 09/09/2020 - 29/01/2021 All data was collected at the University of Southampton, U.K.
