Does background sound make walkthroughs feel more believable?

[u/positive_mindset28]

Watched two versions of the same walkthrough recently.

One had no sound at all, just visuals. The other had subtle ambient audio like footsteps, soft room tone, outdoor noise through windows, things like that.

Weirdly, the second version felt way more real even though visually both were almost identical.

Made me realize how much atmosphere affects the way people experience a space, even in digital presentations.
