Not sure if you’re aware of the history of that film, but it was a William Castle film. Back in the day, he had chairs in the theater wired up to vibrate at that scene in the film…
It was called “percepto” and he did it with several other films. We got to see this in the theater once, and the group that put the viewing on had a chair out in the lobby wired up (and my kid refused to test it out).
