The Pulsed Electro-Acoustic method (used to measure the distribution of space charge) is not based on the relative displacement like most of the other techniques. The aim of this communication is to propose a revision of the PEA method with the help of physics equations. An illustration of the method is provided considering two examples. In the first one, charges have been implanted within an epoxy resin by irradiation with an electron beam. In the second case, charges have been generated in a cross-linked polyethylene by applying voltage
