(COLLEGE FIX) — In the latest on the white supremacy front, a professor at New York State’s Binghamton University says that a “sonic color line” exists in the United States, a “learned cultural mechanism” by which racial differences are established via ways of listening and sounds to “communicate one’s position vis-à-vis white citizenship.”

English professor Jennifer Lynn Stoever provides an example of such: Songs by artists such as Jay-Z, Public Enemy, and KRS-One feature representations of a “cop voice,” or a “racialized way of speaking that police use to weaponize their voices around people of color.”

This “cop voice,” Stoever says according to Science Codex, “provoke[s] fear and extreme forms of compliance from people of color.”
