"Our society has become a lot louder, and we tolerate a lot more noise," says Verna Gibbs, MD, director of NoThing Left Behind and professor of clinical surgery, University of California, San Francisco. That includes the OR, where phones, overhead pages, alarms, suction, ventilation equipment, medical devices such as drills, electronic music devices, conversation (both essential and extraneous), and much more push noise levels higher.
