The story follows Tom More, a psychiatrist living in a dystopian future who develops a device called the Ontological Lapsometer that, when traced across the scalp of a patient, detects the neurochemical correlation to a range of disturbances. In the course of the novel, More admits that the 'mere application of his device' to a patient's body 'results in the partial relief of his symptoms'.
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.
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.
