Sound source localization in virtual reality with ambisonics sound reproduction - Dataset.csv

This dataset was collected for a study on the effect of virtual reality glasses on auditory localization with ambisonics sound production.<br>Participants localized the perceived origin of a ambisonics reproduced sound source, both with and without a virtual reality headset and both blindfolded and with visual information. They used a virtual reality controller to point at the perceived location. <br><br>The localization performance of 21 subjects was measured. All participants provided written informed consent. Note that subject 7, did not have normal hearing thresholds. In the analysis, data from subject 7 were not used in the analysis. The subjectnr is indicated as subject in the dataset.<br>4 ambisonics orders were used to produce the sound sources (1st, 3rd, 5th, 11th). The ambisonics order is indicated in the dataset as ambi_order. <br><br>Stimuli (short noise burst) were presented from -90 to 90 degrees azimuth in 7.5 degrees steps (indicated as x in the dataset). <br><br>6 Conditions were tested: <br><br>1 - Blindfolded without HMD<br>2 - Blindfolded with HMD<br>3 - Visual information without HMD<br>4 - Visual information with HMD------------------------------------------------------5 - Visual localization without HMD (to measure a pointing bias, localization error corrections are based on these data)<br>6 - Visual localization with HMD (to measure a pointing bias, localization error corrections are based on these data)<br>The perceived azimuth and elevation are stored as azi and elev in the dataset.<br>The corrected_err is the perceived azimuth after correcting for the position of the stimulus and pointing biases (calculated using the visual localization data). <br><br>No special software is required to open and analyze the data. <br>
