This document covers the release of the open-source HMDiR dataset (Head-Mounted-Display acoustic impulse responses) of HRTFs, useful to study the occlusion effect of wearing XR devices on the auditory perception. The data was collected for a previous publication in which the effect of wearing HMD gear on the HRTFs of a mannequin was described. This document covers in detail the measurement procedure, equipment, and specifications, including instructions on how to download the data files. The measurement library includes a free-head case (no HMD), two mixed reality headset cases, and three virtual reality headsets, chosen among those commercially available.
