KFC has embraced the trend. In this recent YouTube video, the actor George Hamilton, portraying Colonel Sanders, whispers sweet nothings about pocket squares and enjoys the sounds of KFC's new crispy fried chicken. "This is a community that is absolutely infatuated and enthusiastic about the sensorial experience of sound," KFC CMO Kevin Hochman said in The Washington Post. "There's a lot of comfort that's associated with ASMR, and that's what our food delivers."
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.
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.
