Artifak pendengaran akibat penukaran fungsi pemindahan berkaitan kepala (HRTF) disiasat, menggunakan paparan auditori maya dinamik (DVAD) yang dilaksanakan perisian yang dibangunkan oleh pengarang. DVAD bertindak balas kepada pusingan kepala pendengar menggunakan peranti pengesan kepala dan menukar HRTF untuk mempersembahkan ruang pendengaran maya 3D yang sangat realistik kepada pendengar. DVAD beroperasi pada Windows XP dan tidak memerlukan komputer berprestasi tinggi. Jumlah kependaman sistem (TSL), iaitu kelewatan antara gerakan kepala dan perubahan sepadan isyarat input telinga, merupakan faktor penting DVAD. TSL yang diukur bagi DVAD kami ialah kira-kira 50 ms, yang mencukupi untuk aplikasi praktikal dan eksperimen penyetempatan. Satu lagi perkara yang membimbangkan ialah artifak pendengaran dalam DVAD yang disebabkan oleh menukar HRTF. Penukaran HRTF menimbulkan ketakselanjaran gelombang isyarat binaural yang disintesis, yang boleh dianggap sebagai bunyi klik yang merendahkan kualiti imej bunyi yang dipersembahkan. Analisis ujian subjektif dan corak pengujaan (EPN) menggunakan penapis pendengaran dilakukan dengan pelbagai isyarat sumber dan resolusi spatial HRTF. Keputusan ujian subjektif mendedahkan bahawa persepsi bunyi klik bergantung pada isyarat sumber dan resolusi spatial HRTF. Tambahan pula, analisis EPN mendedahkan bahawa menukar HRTF dengan ketara memesongkan EPN pada frekuensi isyarat mati. herotan tersebut, walau bagaimanapun, disembunyikan secara persepsi oleh isyarat sumber lebar jalur lebar, manakala ia tidak ditutup oleh isyarat sumber lebar jalur sempit, dengan itu menjadikan bunyi klik lebih dapat dikesan. Resolusi spatial HRTF yang lebih tinggi membawa kepada herotan yang lebih kecil. Tetapi, bergantung pada isyarat sumber, bunyi klik yang boleh dilihat masih kekal walaupun dengan resolusi spatial 0.5 darjah, yang kurang daripada sudut boleh didengar minimum (1 darjah di hadapan).

Abstract: Auditory artifacts due to switching head-related transfer functions (HRTFs) are investigated, using a software-implemented dynamic virtual auditory display (DVAD) developed by the authors. The DVAD responds to a listener's head rotation using a head-tracking device and switching HRTFs to present a highly realistic 3D virtual auditory space to the listener. The DVAD operates on Windows XP and does not require high-performance computers. A total system latency (TSL), which is the delay between head motion and the corresponding change of the ear input signal, is a significant factor of DVADs. The measured TSL of our DVAD is about 50 ms, which is sufficient for practical applications and localization experiments. Another matter of concern is the auditory artifact in DVADs caused by switching HRTFs. Switching HRTFs gives rise to wave discontinuity of synthesized binaural signals, which can be perceived as click noises that degrade the quality of presented sound image. A subjective test and excitation patterns (EPNs) analysis using an auditory filter are performed with various source signals and HRTF spatial resolutions. The results of the subjective test reveal that click noise perception depends on the source signal and the HRTF spatial resolution. Furthermore, EPN analysis reveals that switching HRTFs significantly distorts the EPNs at the off signal frequencies. Such distortions, however, are masked perceptually by broad-bandwidth source signals, whereas they are not masked by narrow-bandwidth source signals, thereby making the click noise more detectable. A higher HRTF spatial resolution leads to smaller distortions. But, depending on the source signal, perceivable click noises still remain even with 0.5-degree spatial resolution, which is less than minimum audible angle (1 degree in front).
