Cochlea a protein motor called prestin on their outer membranes; it generates additional movement that couples back to the fluid–membrane wave. This "active amplifier" is essential in the ear's ability to amplify weak sounds. The active amplifier also leads to the phenomenon of soundwave vibrations being emitted from the cochlea back into the ear canal through the middle ear (otoacoustic emissions). Otoacoustic emissions are due to a wave exiting the cochlea via the oval window, and propagating back through the middle ear to the eardrum, and out the ear canal, where it can be picked up by a microphone.

Errors of the Human Body Ruzin of Screen Invasion wrote, ""Errors of the Human Body" is elevated by a sublime turn by star Michael Eklund... His agony, particularly in the third act, is brilliantly painful. Despite the screenplay skimming over his character’s supposed scientific prowess, to the film’s moderate detriment, Eklund’s powerful performance is nonetheless tragic and captivating." Michael Treveloni of Film School Rejects noted, "The film is a not just a science-fiction horror story: it is a commentary on the importance of dialog, showcasing the need for communication in its many forms. With Geoff, "Errors" presents the perfect, damaged subject.". At the Fantastic Fest
