very interesting
certain noises make me agitated or nervous while whispering depending on the source can be pleasant or infuriating which might be related to something similar
to those suffering (enjoying?) this. would you say that it might be a form of Synesthesia http://en.wikipedia.org/wiki/Synesthesia wherein your brain confuses certain senses with others and often gives them a duality? being able to taste colours or smell sounds for example. if that was the case i would imagine certain sounds would be exhibited as pleasant while others would be offensive or irritating. is that the case for anyone?
I'm no neuroscientist, but based on my own experience I don't think so, at least not entirely. The particular sound of teeth crushing ice (or anything that closely approximates is) is a trigger for me, but I get more than the simple "buzz" people keep talking about. When I hear it, there's a fuzziness in my scalp and along the back of my neck, but I also feel the sensation of the vibrations of my molars rubbing against the ice, and the distinct pops as the ice cracks. Depending on how loud/crunchy the sound is, my jaw will actually feel cold. As far as I can tell, it's tied to a distinct sensory memory of a particular time that I chewed on ice, and not because of synesthesia.
EDIT: After going through that this [http://www.youtube.com/watch?v=xlDFG2SCgn8] trigger compilation video, I'm definitely more inclined to believe it's tied to sensory memory. The frosted glass in particular immediately brought back memories of a glass chess set I used to have, and how I would rub the frosted pieces together, or run my nails along the frosted parts of the board to feel the vibrations. Squeezing the stuffed soccer ball worked as well; if she'd had a bigger stuffed thing (like a stuffed animal or one of those fake mini-American-footballs) and squeezed it more intently, I would have had a much more pronounced response.
I find it curious that the ASMR videos focus on the very quiet and the subtle--my triggers seem to require more volume or longer sounds, and I highly doubt I'm the only like this. Like running a fingernail along the teeth of a zip-tie (hee hee, just thinking about one gives me fuzzies), or the hum of an iron bar.
