Abstract: The low frequency vibration spectrum of a surface fractal with a rigid fractal boundary presents a smaller density of states than an ordinary resonator. Such vibrations, called fractinos, should be present in partially phase separated glasses if one component is soft. In addition the interfaces between the phase separated regions are fractal diffusion fronts which are mass fractals close to percolation cluster hulls. It is proposed that the fractons which have claimed to exist in these non-fractal materials are the vibrations of these internal interfaces.
