The invention relates to a method and a device for locating an event transmitting a signal, including a set of sensors (Ai-Am) to measure the response times of the said signal, and processing means (3) to solve a system of equations defining distances between the said sensors and the said event as a function of a speed of propagation of the said signal and of an offset of the said response times relative to a reference time, where the device also includes: processing means (3) to recommence multiple times the solution of the system of equations, each time modifying the response time of at least one of the said sensors according to a local variation, and processing means (3) to determine the location of the event as a function of the positions obtained when the different solutions of the system of equations are found.
