A Collection of BRIRs for a Listener Wearing Different Types of Open Headphones

<p><strong>Introduction:</strong></p> <p>The following data set was collected to study the influence of several open headphone models on a real sound source.<br> This investigation was motivated by studies on augmented acoustic reality (AAR) scenarios. In AAR applications virtual sound sources are usually played back using binaural synthesis over headphones with the goal to blend in with the real acoustic environment. Due to the presence of headphones, additional scattering, resonance and shadowing effects are introduced to the real sound field.&nbsp;<br> The data set consists of binaural room impulse responses (BRIRs) measured with a KEMAR 45BA wearing different open headphone models. The measurements were carried out in the listening laboratory at the TU Ilmenau. Two distances (75cm and 200cm) and 92 angles (4&deg; azimuthal resolution incl. 90&deg; and 270&deg;)&nbsp;were measured. Each configuration was measured three times with a repositioning of the headphones.</p> <p><strong>Important notes:</strong><br> - The mat-files contain the BRIR matrix with the dimensions samples-channels-angles<br> - The mat-files contain an angle vector for the corresponding azimuthal steps<br> - The head rotation angle runs clockwise</p> <p>&nbsp;</p> <p>The data set was presented at DAGA 21 [1].<br> A perceptual analysis using this data set can be found in [2].</p> <p>&nbsp;</p> <p><strong>References:</strong><br> [1] Schneiderwind, C., Neidhardt, A., &quot;Data Set: A Collection of BRIRs for a Listener Wearing Different Types of Open Headphones&quot;, DAGA 2021, Wien, Austria, August 2021.<br> [2]&nbsp;Schneiderwind, C., Neidhardt, A., and Meyer, D., &ldquo;Comparing the effect of different open headphone models on the<br> perception of a real sound source,&rdquo; 150th AES Convention, Online, June 2021.&nbsp;</p>
