“…The participant was instructed to sit comfortably facing speaker no. 1, marking 0° azimuth, not to move their head during stimulus presentation and had to respond by naming the speaker number of the presented stimuli [22]. The responses were recorded and stored using a custom MAT-LAB code.…”

Background and Objectives: Traditional sound field localization setups in a free-field environment closely represent real-world situations. However, they are costly and sophisticated, and it is difficult to replicate similar setups in every clinic. Hence, a cost-effective, portable, and less sophisticated virtual setup will be more feasible for assessing spatial acuity in the clinical setting. The virtual auditory space identification (VASI) test was developed to assess spatial acuity using virtual sources in a closed field. The present study compares the legitimacy of these two methods.Subjects and Methods: Fifty-five individuals with normal hearing (mean age±SD: 21± 3.26 years) underwent spatial acuity assessment using two paradigms: 1) the sound field paradigm (localization test) and 2) the virtual paradigm (VASI test). Location-specific and overall accuracy scores and error rates were calculated using confusion matrices for each participant in both paradigms.Results: The results of Wilcoxon signed-rank tests showed that the locationspecific and overall accuracy scores for both paradigms were not significantly different. Further, both paradigms did not yield significantly different localization error rates like right and left intra-hemifield errors, inter-hemifield errors, and front-back errors. Spearman’s correlation analysis showed that all the measures of the two paradigms had mild to moderate correlation.Conclusions: These results demonstrate that both VASI and the sound field paradigm localization test performed equally well in assessing spatial acuity.

Purpose: The virtual acoustic space identification (VASI) test was designed to assess spatial-hearing acuity by simulating sound location perception in a closed field (under headphones). The utility of this tool in children can be asserted only if the test results are consistent across measurement sessions, which is evaluated in this study using test–retest reliability assessments. Method: The VASI test assessed the spatial abilities of 40 typically developing school-aged children aged 7–13 years ( M age = 10.47 ± 1.83 years, 22 boys, 18 girls). The test consisted of eight virtual location percepts (with 45° separation) produced under headphones (Sennheiser HD 569). Each spatial percept was presented randomly 7 times at 65 dB SPL. Each participant completed the assessment in three measurement sessions (baseline, intrasession, and intersession). The accuracy scores at each location and overall accuracy scores were compared across the sessions. Results: The Shapiro–Wilk test indicated that the VASI data were not normally distributed. Intraclass correlation coefficient analysis revealed excellent test–retest reliability of the overall accuracy scores and moderate-to-high reliability of location-specific scores. This was complimented by the low response variability of the overall and location-specific accuracy scores. The Bland–Altman analysis also indicated minimal bias in VASI accuracy scores across the three sessions. Conclusions: It can be concluded from the results that VASI is a reliable tool for assessing spatial-hearing acuity in school-aged children. The high test–retest reliability and ease of portability make the test highly relevant for classroom setups where early diagnosis and intervention of spatial deficits can play a critical role in determining the academic success of school-going children.
