In this talk, Lentjes discusses her upcoming academic paper, "Ultra/Sound: The Antiabortion Weaponization of Sonic Vitalism," which examines how the United States antiabortion movement wields obstetric technology, such as ultrasound and fetal cardiac activity tests, as a tool for subjugating pregnant people. Through a process Lentjes terms 'sonic vitalism', the antiabortion movement successfully politicizes and weaponizes acoustic technology, lending credibility to the fiction of fetal personhood and then broadcasting it in the medical, legal and sociocultural spheres. Lentjes' paper argues that antiabortion sonic vitalism engenders not only a discursive construction of the fetus-as-person, but also a lived reality in which pregnant people are literally denied healthcare every day.
