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. 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.
Richard, who is also the author of Brain Tingles: The Secret to Triggering Autonomous Sensory Meridian Response for Improved Sleep, Stress Relief, and Head-to-Toe Euphoria, estimates around 20 per cent of the population experience strong ASMR. What triggers people may come down to individual preferences. “The key to triggering ASMR is to create gentle sounds,” he says. Richard’s own triggers include eye exams and [the Netflix series] The Joy of Painting with Bob Ross.
I had an abnormal psychology professor in undergrad that would have me drooling by the end of class because her voice was so “soothing”. Lately, I have found that instructional videos via Youtube do the trick. I’m embarrassed to say, but I watched a video of some random guy giving a tutorial on how to properly clean out your ear for roughly a year (lol). I can watch nearly anything instructional to induce the sensation, but I am drawn to videos in which the narrator has an accent.
I would spend all Friday, Saturday drawing outlines with my 3 best friends, discussing art, colour and symmetry for hours, then spend all Saturday night bombing trains, painting together would activate it intensely, in the dark, spooky and exhilarating all at the same time, while four kids spent their weekends silently breaking the law to paint Top-to-Bottom Wholecars just for art’s sake)
One category depends upon external triggers in order to experience the localized sensation and its associated feelings, which typically originates in the head, often reaching down the neck and sometimes the upper back. The other category can intentionally augment the sensation and feelings through attentional control, without dependence upon external stimuli, or 'triggers', in a manner compared by some subjects to their experience of meditation.
Many of those who experience ASMR report that some specific non-vocal ambient noises are also effective triggers of ASMR, including those like the sound of rain, fingers scratching or tapping a surface, the crushing of eggshells, the crinkling and crumpling of a flexible material such as paper, or writing. Many YouTube videos that are intended to trigger ASMR responses capture a single person performing these actions and the sounds that result.
