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.
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.
