### Results of the Survey and Statistical Analysis
Comprising QNs 6, 19, 15, and 14, 'Component 3', which explains 8.590% of the total factor, can be described as 'consideration of acoustic control and accessibility' in terms of the granularity of sound volume and sound effect control in the metaverse environment and \begin{table}

Table 11: Results of principal component analysis. the ability to turn different kinds of sounds on and off. In particular, since 'Component 3' is the component with the most AUX evaluation factors, including'sufficiency of volume control' (QN 19), 'ease of access to sound control' (QN 14), and the auditory presence evaluation factor 'distraction from sound' (QN 6), it is judged that the AUX evaluation factor itself does not improve the sense of presence, but the sense of presence can be improved by controlling 'distraction from sound' (QN 6) through acoustic control and accessibility considerations. Comprising QNs 11, 12, and 9, 'Component 4', explained as 7.848% of the total factor, is characterized by 'auditory utility and minimalist design' in the sense that AUI such as notifications and signals that help navigate in the metaverse environment should be designed in such a way that users do not notice the sound looping. In particular, 'Component 4' states that'signals that help with navigation' (QNs 11, 12) are not just AUI, but auditory signals that are experienced in the real world (such as car horns), and if the auditory signals are mechanically repeated, the sense of presence is diminished.
