From our method of phonon density of states superposition method it is inferred that a possible connection between 1/f noise parameter and the Eliashberg function could exist. According to this hypothesis, the temperature dependence of the 1/f noise parameter would follow the energy dependence of the Eliashberg function. The existing noise data for tin(Sn). polycrystalline aluminum(Al) and a copper(Cu) nanobridge are compared with the corresponding Eliashberg functions. Striking resemblances are found. ©1999 American Institute of Physics.
