Hi Douglas, There were a few studies that looked at using training to improve localization using non-individualized hrtfs some years back. From memory, the results were a bit mixed and most used dynamic training methods so that would include head tracking. The counter-argument for using non-individualized hrtfs is that the sound gets “colored”. That is, the spectrum gets changed in a way that is different to one’s own hrtf.
Kind regards Alan From: Sursound <sursound-boun...@music.vt.edu> On Behalf Of Douglas Murray Sent: Friday, 21 April 2023 6:14 PM To: Surround Sound discussion group <sursound@music.vt.edu> Subject: Re: [Sursound] ASA Academy short course on “Fundamentals of Binaural Hearing” Survey Hi Alan, Thanks for asking. I’ll have to be a bit clearer about my question about binaural. For me binaural listening has never been more than a vague spatial quality in the sound. Sometimes it sounds more “natural” than stereo. Specific locations are not clearly localized. Add head tracking and things become much clearer. But without head tracking the sound field remains vague. In early experiences with binaural without head tracking I found the effects lacking in the very thing it was supposed to be delivering: more accurate localization than with volume based panning. More recently, after many hours of attentive listening, I have found the effect more convincing. So my question is, is the effective localization of binaural sound a learned skill? And if so, can the skill be taught?
