The study is still ongoing, and results have not yet been published. But for his part, Richard has been developing a theory of what ASMR is and why it exists. His theory isn't exactly scientific, but it is beautiful: He notes that the quality that underlies almost all ASMR videos is what’s been called a “tranquil, womb-like intimacy.” That is, ASMRtists speak softly into the ears of headphone-wearing viewers, gently coaxing them to sleep by way of assiduous personal attention, comforting words, smiles and simulated stroking. At its most essential level, Richard believes, all the intimacy channeled through towel foldings and whispered affection is about triggering the felt experience of being loved.    
Like those who posted before me, I have experienced ASMR for many years. My earliest memories are around the second grade. In my second grade class, we were required to read with partners; however, I was a more advanced reader and would allow my partner to read the entire time if he/she wanted. I would experience intense tingling around the crown of my head listening to him/her read, but I would also experience very intense tingling in the frontal lobe region watching him/her turn the book pages. Around the same time, I would intentionally watch Bob Ross on PBS (like others have mentioned) to take a nap due to the same tingling sensation and calm/relaxation he induced.
I have just found out about ASMR, and never knew there was an actual name for how I became so mesmerised by certain things. I don’t get tingles or anything physical, just get so entranced by the “thing” that nothing else matters, and I end up staring like a hypnotised fool at whatever the trigger has been! haha! Mostly it is aural, like accidental whispering (I don’t enjoy the deliberate whisper videos on Youtube), crinkling of packages (again, accidental, not deliberate), or sometimes it is visual, like someone quietly playing with their hair, or gently rummaging in their bag for something.
I just discovered I was capable of triggering tingles on purpose this past month, after it popped into my head one day to seek out a video of a cat grooming itself (my trigger) to see if I could purposely trigger that weird relaxing feeling that I had experienced occasionally growing up, but had never really fully thought about. So that was pleasant. Then oddly enough a week ago I attempted to articulate this experience to a friend at a party (not knowing the term ASMR – nor even aware that it was a known thing, I simply described it as this peaceful, totally non-sexual, relaxed feeling I get from watching cats grooming themselves). Against all odds, this friend said, “oh, you’re probably experiencing ASMR – you should look it up.” Needless to say – it’s nice to find that indeed there’s an entire community of people online that have the same capability. Thought I’d share my experience and ask a couple questions.
Jacob Daniel is clearly a savvy child – although excitable and eccentric, he talks soberly about safety on YouTube, clapping his hands as he tells children to “be, be safe”. He tells kids to use fake names, access their email with VPNs, and avoid making custom Skype calls with viewers. For all his intelligence, however, Daniel is still a child. He and Prunkl show off a series of wigs they play with at home – he dons a purple one with red horns; Prunkl shows me her doll. They talk excitedly about the pranks they play on the public, wearing the wigs to order food in take-away shops.

These reports have precipitated comparison between ASMR and synesthesia – a condition characterised by the excitation of one sensory modality by stimuli that normally exclusively stimulates another, as when the hearing of a specific sound induces the visualization of a distinct color, a type of synesthesia called chromesthesia. Thereby, people with other types of synesthesia report for example 'seeing sounds' in the case of auditory-visual synesthesia, or 'tasting words' in the case of lexical-gustatory synesthesia.[42][43][44][45][46]
But creating an ASMR video isn't as simple as filming for an hour. Maria said her more complex videos take about three days to create. She'll write up a script with specific soothing words she should be using and do research into what sounds she should incorporate. She tests out the appropriate lighting and sound levels before filming. She sets up microphones positioned where a viewer's ears would be in real life, and places the lens where a onlooker's eyes would be. Then, after filming the video, she goes into post-production, which includes a special ear toward sound to remove any clap or loud noise.
Allen verified in a 2016 interview that she purposely selected these terms because they were more objective, comfortable, and clinical than alternative terms for the sensation.[10] Allen explained she selected the word meridian to replace the word orgasm due to its meaning of point or period of greatest prosperity.[clarification needed][citation needed]
