Abstract
Background
Recent developments in virtual acoustic technology has levered promising applications in the field of auditory sciences, especially in spatial perception. While conventional auditory spatial assessment using loudspeakers, interaural differences and/or questionnaires are limited by the availability and cost of instruments, the use of virtual acoustic space identification (VASI) test has widespread applications in spatial test battery as it overcomes these constraints.
Purpose
The lack of test-retest reliability data of VASI test narrows its direct application in auditory spatial assessment, which is explored in the present study.
Methods
Data from 75 normal-hearing young adults (mean age: 25.11 y ± 4.65 SD) was collected in three sessions: baseline, within 15 min of baseline (intra-session), and one week after baseline session (inter-session). Test-retest reliability was assessed using the intra-class correlation coefficient (ICC), coefficient of variation (CV), and cluster plots.
Results
The results showed excellent reliability for both accuracy and reaction time measures of VASI, with ICC values of 0.93 and 0.87, respectively. The CV values for overall VASI accuracy and reaction time 9.66% and 11.88%, respectively. This was also complemented by the cluster plot analyses, which showed 93.33% and 96.00% of temporal stability in the accuracy and reaction time measures, indicative of high test-retest reliability of VASI test in auditory spatial assessment.
Conclusions
The high temporal stability (test-retest reliability) of VASI test validates its application in spatial hearing test battery.
期刊介绍：
Journal of Otology is an open access, peer-reviewed journal that publishes research findings from disciplines related to both clinical and basic science aspects of auditory and vestibular system and diseases of the ear. This journal welcomes submissions describing original experimental research that may improve our understanding of the mechanisms underlying problems of basic or clinical significance and treatment of patients with disorders of the auditory and vestibular systems. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines. Journal of Otology welcomes contributions from scholars in all countries and regions across the world.
