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.
"ASMR videos tend to have low production costs, but have a massive replay-ability factor," Burns explained. "'Baba the Cosmic Barber's original head massage video has almost 10,000,000 views. Many of those views come from people who probably watch it several times a week to fall asleep. Ten million views is incredible for a video that costs less than fifty dollars to make."
Listening to a binaural recording through headphones simulates the binaural hearing by which people listen to live sounds. For the listener, this experience is characterised by two perceptions. Firstly, the listener perceives being in close proximity to the performers and location of the sound source. Secondly, the listener perceives what is often reported as a three-dimensional sound. This means the listener can perceive both the position and distance of the source of sound relative to them.
As Drenge put it to us, “the online slime craze popularized through Instagram and YouTube has touched on something deep within us.” According to the hypothesis that they tested with the video itself, “short, attention-sapping clips of Technicolor liquids reacting to a variety of stress tests tickle the base nerves of the brain. MRI scans show activity in the same parts of the brain that react to hypnotism and childhood comforts, brought on by warm blankets and lullabies. Scientists are reluctant to reveal any secrets but rumours are swirling with regards to an obscure cortex known as Deep Baby Brain. We are beginning to unlock deep secrets about the human psyche.”
The study asked a range of questions about where, when and why people watch ASMR videos, whether there was any consistency in ASMR-triggering content, as well as whether individuals felt it had any effect on their mood. There was a remarkable consistency across participants in terms of triggering content – whispering worked for the majority of people, followed by videos involving some sort of personal attention, crisp sounds, and slow movements. For the most part, participants reported that they watched ASMR videos for relaxation purposes, or to help them sleep or deal with stress. Only 5% of participants reported that they used ASMR media for sexual stimulation, which is counter to a common perception of the videos found online. “There are a lot of people who latch onto some ASMR videos involving attractive women and dismiss what we found to be a very nuanced activity as exclusively sexual. Our findings will hopefully dispel that idea,” explains Barratt. “The fact that a huge number of people are triggered by whispering voices suggests that the sensation is related to being intimate with someone in a non-sexual way. Very few people reported a sexual motivation for ASMR, it really is about feeling relaxed or vulnerable with another person,” adds Davis.
While most girls her age earned their pocket money babysitting the neighbours’ kids, Kelly spent that summer in her bedroom filming 50 custom-made ASMR videos. She would receive daily email requests for bespoke videos, shoot the footage, receive the money over PayPal (ten minutes cost $50, whereas for $30 (about £23) you’d get a five-minute clip) and upload the video to her YouTube channel, Life with Mak.
Kelly knows that she inspires other kids to take up ASMR – children at school ask for advice on how to make popular YouTube videos. At one football game recently, kids swamped Kelly for photos. “It was like… crazy,” Kelly whispers dramatically. “I went with friends and we walked past this group of cheerleaders and they all got quiet. They came up one after another and were like, ‘Let’s take a picture.’”
In addition to the effectiveness of specific auditory stimuli, many subjects report that ASMR is triggered by the receipt of tender personal attention, often comprising combined physical touch and vocal expression, such as when having their hair cut, nails painted, ears cleaned, or back massaged, whilst the service provider speaks quietly to the recipient. Furthermore, many of those who have experienced ASMR during these and other comparable encounters with a service provider report that watching an "ASMRtist" simulate the provision of such personal attention, acting directly to the camera as if the viewer were the recipient of a simulated service, is sufficient to trigger it.
