Geophone and method for the study of elastic wave phenomena
No full textA method for the study of elastic wave phenomena in the ground, where the detection of said phenomena is carried out with the use of at least a geophone comprising at least a couple of transducers (20, 21; 37, 38), each transducer (20, 21; 37, 38) being apt to detect horizontally polarized shear waves, represented by SH signals, and compression waves, represented by P signals. The method comprises: i) a first detection, by means of one of said transducers (20, 21; 37, 38) of the sum of said P and SH signals (P+SH); ii) a second detection, by means of the other one of said transducer (20, 21; 37, 38) of the difference between said P and SH signals ([P-SH] or [-P+SH]); iii) the compensation ([P+SH]-[P-SH]) or ([P+SH]+[P-SH]) between said first and said second detection, in order to acquire signals being representative of horizontal polarized shear waves with an increased sensitivity and being less affected by the presence of compression waves
