Validation of binaural recordings with head tracking for use in soundscape evaluation

Given that sounds in real-life environments and soundscapes possess direction and distance cues, it is essential to replicate these cues in virtual reality (VR) simulations used for soundscape evaluation, to ensure that the results obtained have high ecological validity. One way to replicate the des...
