Example acoustic emission sensors with integral acoustic generators are disclosed. Example apparatus disclosed herein include an acoustic receiver, an acoustic generator, and a wear plate. The acoustic generator is disposed adjacent to the acoustic receiver. The wear plate is acoustically coupled to the acoustic receiver and to the acoustic generator. The wear plate is to convey acoustic energy from the acoustic generator to the acoustic receiver through a structure under test to which the apparatus is coupled. The wear plate includes first acoustic isolation to impede transmission of acoustic energy from the acoustic generator to the acoustic receiver through the wear plate.
