Comparison of a Head-Mounted Display and a Curved Screen in a Multi-Talker Audiovisual Listening Task
It addresses audiovisual technology preferences for hearing research, but is incremental as it compares existing displays without introducing new methods.
This study compared a head-mounted display and a curved screen in multi-talker audiovisual listening tasks, finding that older normal-hearing participants preferred the curved screen and video recordings, while young and older hearing-impaired participants showed no preference.
Introduction: Virtual audiovisual technology and its methodology has yet to be established for psychoacoustic research. This study examined the effects of different audiovisual conditions on preference when listening to multi-talker conversations. The study's goal is to explore and assess audiovisual technologies in the context of hearing research. Methods: The participants listened to audiovisual conversations between four talkers. Two displays were tested and compared: a curved screen (CS) and a head-mounted display (HMD). Using three visual conditions (audio-only, virtual characters and video recordings), three groups of participants were tested: seventeen young normal-hearing, ten older normal-hearing, and ten older hearing-impaired listeners. Results: Open interviews showed that the CS was preferred over the HMD for older normal-hearing participants and that video recordings were the preferred visual condition. Young and older hearing-impaired participants did not show a preference between the CS and the HMD. Conclusions: CSs and video recordings should be the preferred audiovisual setup of laboratories and clinics, although HMDs and virtual characters can be used for hearing research when necessary and suitable.
