Smith speculates that ASMR may be similar to synesthesia, the fascinating neurological condition in which people see numbers in color and “taste” shapes. “In synesthesia,” he says, “there have been some studies that show there’s slightly atypical wiring in the brain that leads to slightly different sensory associations, and I think that may be the same thing we have here.”
It’s not really a physical feeling if that makes sense, but there is a powerful reaction to the sounds nonetheless, to the point where I’m instinctively arching my neck, and a feeling does wash over you that is truly unique, almost addictive. What I don’t fully understand is why my mind chose just now to react when I haven’t had anything close to an ASMR experience before. I’d say that I’ve just found the right trigger, but I’m even reacting to videos that did nothing for me in the past. Like something clicked in my head recently.
Binaural recordings are made specifically to be heard through headphones rather than loudspeakers. When listening to sound through loudspeakers, the left and right ear can both hear the sound coming from both speakers. By distinction, when listening to sound through headphones, the sound from the left earpiece is audible only to the left ear, and the sound from the right ear piece is audible only to the right ear. When producing binaural media, the sound source is recorded by two separate microphones, placed at a distance comparable to that between two ears, and they are not mixed, but remain separate on the final medium, whether video or audio.
My sensations occur randomly and normally while I am sitting at the computer browsing the net, reading email, or playing my favorite games. I have not noticed a specific trigger and therefore have become concerned that it might be symptomatic of an underlying medical disorder… pending heart attack, diabetic neuropathy or a sinus irritation. I finally chose the correct key words to get Google to lead me here. I just downloaded the book so haven’t read it yet.
“When a newborn is born, the sensation that is the most developed and they receive the most information through is touch, and the one that’s least developed is sight,” he says. Parents show infants love most of all through touch, he argues—coddling, stroking—and all of this helps explain why ASMR is, at its best, an in-person experience with echoes of childhood experiences.
ASMR is usually precipitated by stimuli referred to as 'triggers'. ASMR triggers, which are most commonly auditory and visual, may be encountered through the interpersonal interactions of daily life. Additionally, ASMR is often triggered by exposure to specific audio and video. Such media may be specially made with the specific purpose of triggering ASMR or originally created for other purposes and later discovered to be effective as a trigger of the experience.
