Frequency X

Frequency X was a controversial audio that was originally invented by J.F. Sweets, and was implemented in their fast food kiosk machines.
The core concept behind Frequency X was that by generating precise frequencies and patterns similar to binaural brainwave entrainment audio, it could essentially manipulate a customers emotions and trigger dopamine release, which resulted in a significant increase of returning customers.
However, numerous studies later revealed that prolonged exposure to Frequency X actually caused severe abnormalities and disruptions to neural network formation and in some extreme cases caused chronic brain ligma.
