For the presence-ratings from 1 to 100, the factor “Soundscape” was highly significant, F (1, 35) = 48.95, p < 0.001, with a large effect size (η 2 = 0.583), while the factor “Steps” had no significant effect, F (1, 35) = 0.003, p = 0.96, nor did their interaction, F (1, 35) = 0.531, p = 0.471.
As in Experiment 1, a significant correlation between the rated synchronicity of the step sounds and the perceived realism of the VR was found, r = 0.40, t (78) = 3.89, p < 0.001, but in Experiment 2, synchronicity was also related to overall presence: A significant correlation was found with the 1–100 presence scale, r = 0.28, t (78) = 2.61, p < 0.05, and marginal significance when correlating synchrony ratings with the single-item presence scale of the IPQ.
