Hello Dingding, There are various elements which improve static binaural rendering. Rather than repeat the various elements here, I invite you to check some more of the literature, such as the chapter that Rozenn and I wrote for this book : B. F. G. Katz and R. Nicol, “Binaural spatial reproduction,” in Sensory Evaluation of Sound (N. Zacharov, ed.), pp. 349–388, Boca Raton: CRC Press, 2019, (url). ISBN 978-1-4987-5136-0. I can also say (as another element of small self-promotion) we have incorporated many if the techniques in our free binaural VST plug-in (http://anaglyph.dalembert.upmc.fr/) with this goal in mind. I invite you to try it out. From your text, I have the impression that you distinguish between “clearly and reliable” responses (repeatability of subjects) as being distinct from the actual desired rendering location. This is not really compatible with your following goal of distinguish between front and back, as well as between above and below, unless you mean in their personal remapping of the perceived HRTF space. So, are you looking for “reliable” or “correct”? This is not exactly clear in your statements. Best of luck, -Brian -- Brian FG Katz, Research Director, CNRS Groupe Lutheries - Acoustique – Musique Sorbonne Université, CNRS, UMR 7190, Institut Jean Le Rond ∂'Alembert http://www.dalembert.upmc.fr/home/katz De : AUDITORY - Research in Auditory Perception <AUDITORY@xxxxxxxxxxxxxxx> De la part de Dingding Yao Dear list, I hope this message finds you well. I am reaching out to seek your advice on a question related to binaural reproduction. As we all know, localization ambiguities—especially front-back and up-down confusions—are a common challenge when using HRTF-based binaural playback. Previous literature has pointed out several influencing factors, such as dynamic cues (e.g., head rotation), individualized HRTFs, and headphone equalization. However, I am particularly interested in whether it is still possible to achieve a clear sense of directional perception under static listening conditions with non-individualized HRTFs. Specifically, even if precise localization is not attained, might there be techniques or strategies that allow listeners to clearly and reliably distinguish between front and back, as well as between above and below? |
