Furthermore, in the framework of the Jordan-Brans-Dicke theory, I compute the signal to noise ratio for a resonant mass detector of spherical shape and for binary sources and collapsing stars. Finally I compare these results with those obtained from laser interferometers and from Einsteinian gravity.23 pages, talk delivered at the 2nd SIGRAV school on gravity, como italy, iopconf.sty neededGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
