Get your ears out for the lads. Let's see 'em.
Chances are they're very different from the "average". Cerny wants Tempest 3D AudioTech to be for everyone, and they're researching ways of being able to create your own HRTF profile, either by sending a picture of your ears and letting machine learning do the rest, sending a video of your ears to kind of 3D scan them and infer how they interact with sound, or by something like a VR game where you point and pull a trigger at where you think something is coming from so that your HRTF is gradually learned and refined over time.
At launch PS5 will just ship with 5 profiles where 1 may give you a better effect than the default.
