Acoustic recordings were carried out during these tests. With the aim of characterizing injection states,the study wants to verify the following hypotheses: − the frequential characteristics of signals recorded outside periods of injections and during the injections of water and argon are different; and − the presence of an injection causes a modification of filtering characteristics between sources and the sensors. These modifications of characteristics differ from sensor to sensor.Show less >
