These are are relevant From my point of view for head above torso impact. If this could be included in head tracked conversion for FOA to binaural, I think it would improve it. One way would be to assume stationary torso with head rotation only for +-30 degrees rotations. https://www2.ak.tu-berlin.de/~akgroup/ak_pub/2014/Brinkmann_2014_HATO_AudibilityForumAcusticum.pdf&ved=0ahUKEwj-se-KwtLKAhUFwHIKHYX6CWAQFggwMAg&usg=AFQjCNFvpDg_B80ord_TZxbCdgz80mHf8w&sig2=XejBVFKZvy1ULG1of-PjBA I have not rad all of it.
