Auditory exclusion

Auditory exclusion is a form of temporary loss of hearing occurring under high stress. As such it is related to tunnel vision and "the slowing of time in the mind". The phenomenon is discussed in the literature on law enforcement officers and soldiers.

In 2016, the attorney for Tulsa police officer Betty Shelby wanted to the jury to hear about how auditory exclusion could have played a role when the officer fatally shot Terence Crutcher, an unarmed 40-year-old black male.[1]
