Efficacy of virtual reality pure-tone audiometry in training of hearing test for audiologist

Abstract

Background and objectives: The immersive virtual reality (VR) simulator is advantageous because it is cost-effective, realistic, can be controlled directly by the user, and can be integrated into education and training in otorhinolaryngology. The present study explored the feasibility of incorporating VR pure-tone audiometry (PTA) into an audiologist training curriculum, and assessed audiology experts’ willingness to use a VR PTA. Materials and methods: A total of 31 audiologists (16 skilled audiologists and 15 undergraduate students) participated in the study, using a developed VR PTA application with a Meta Quest 2 device. A digital twin technique was applied for a realistic environment. The study measured key components of the VR system and behavioral intention to use VR PTA and traditional PTA using a modified version of the Technology Acceptance Model survey. The survey outcomes for VR PTA and the traditional PTA were compared, using a paired t-test and W test. Results: The general characteristics of the participants were homogeneous. In the homogeneity test, no statistically significant differences were found between the ratings of VR PTA and traditional PTA. The comparison between VR PTA and traditional PTA revealed no significant differences between skilled audiologists and undergraduate students for all variables. Conclusions: The VR PTA and traditional PTA had no differences in of VR system characteristics and behavioral intention to use. The efficacy of the VR PTA was validated, and previous experience with traditional PTA was not affected by adopting VR PTA. Further studies are needed to assess performance enhancements in audiological testing through VR simulation.
