Consider an infinite linear mass-spring system and a modification of itobtained by changing the first mass and spring of the system. We give resultson the interplay of the spectra of such systems and on thereconstruction of the system from its spectrum and the one of themodified system. Furthermore, we provide necessary and sufficientconditions for two sequences to be the spectra of the mass-springsystem and the perturbed one.
