“Some of the instruments fall below the human hearing range, only the vibrations can be felt,” feels unreal to me for some reason. I can’t imagine a vibration rattling through me without hearing something at that power.
It's used to rattle more than just humans with processes like DFAT [0]. Here's the NASA handbook on their use [1].
For experiences that are a little more human friendly, subsonic audio is something that's also explored more commonly in the noise art. Stefanie Egedy [2] is one artist that's been working in that space lately.
Apparently this is a thing that was used in old horror movies.
Subsonic music would play just before a scary encounter, creating a feeling of uneasiness to the audience without any consciously perceptible stimulous, and thus priming the audience for the horror to come.
