I've been aware of the ASMR feeling since about always, but I really thought it was something everyone got. As common as breathing, so it never occurred to me to speak about it until recently when I gave my sister a few links that made me feel these triggers and she felt nothing or was even greatly annoyed... then I came across reading about it and realized, not all people get it. (They're totally missing it, I like it a lot!)
Finally something to explain my “photocopier man” feeling which has been a standard joke in our family. I first discovered this feeling when I was a teenager working in an office where a repair man would come regularly to maintain the photocopier and I would experience this sensation of well-being while he was working. It was in a fairly small office and usually he would clean the screen with an acetone base cleaner so I always thought that the fumes from that created a mini “high”. I have had it at various times usually when there is someone repairing something in the office eg putting data cables, fixing sockets etc. I now work in a research lab and have had it when participants are in another room being tested with senors on their heads and I have no visual or auditory input from them just the sense of them being there. I have had it to a lesser extent from acupuncture and find massage of any kind extremely unpleasant. It’s nice to find out that it’s not just me that has this strange feeling for no apparent reason.
I’m not really sure if I have ASMR or not – I literally discovered it was an actual thing a few minutes ago – but I am very sensitive to sounds. Certain chord progressions or note progressions in songs, and other sounds like people eating watermelon give me the tingling feeling described. But I also get the opposite. For some reason, certain sounds make me feel queasy and sick (like the sound of someone pulling a string through their fingers). Is this ASMR, or related? Or if it’s not, does anyone know what that is?
Some ASMR video creators use binaural recording techniques to simulate the acoustics of a three-dimensional environment, reported to elicit in viewers and listeners the experience of being in close proximity to actor and vocalist.[33] Binaural recordings are usually made using two microphones, just like stereo recordings. However, in binaural recordings the two microphones tend to be more specially designed to mimic ears on humans. In many cases, microphones are separated the same distance as ears are on humans, and microphones are surrounded by ear-shaped cups to get similar reverb as human ears.

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]
