I remember Rhett and Link talking about this once, and they suggested everyone watch this one video that went through a variety of sounds and ranges of hertz and whatnot so that anyone watching could figure out what triggers the goosebumps. ASMR I believe covers more than just whispering, but its not quite white noise either. And white noise has become quite popular along side it. I listen to Star Trek TNG engine noise as white noise to sleep to when my girlfriend isn't around (even though she falls asleep to netflix, youtube, and a variety of fans and machines in the room, she has some weird issue with me listening to music and specific white noise while we try to sleep). I've yet to figure out if any type of whispering or hair brushing noises do anything for me

The videos you watch, are they just calming, or have you found the particular frequency that sets your body off? Indeed it isn't really a sexual thing, though it can be arousing. But that's just because it's a physical response. Goosebumps is the most frequent response. I need to go give myself goosebumps
