Abstract
The main theoretical predictions on vibrational excitations of fractal networks are first summarized. The application of the fracton theory to glasses and other amorphous materials is then critically discussed. The early experimental evidence for fractons obtained on demonstrated fractal systems is also surveyed. Finally, the extensive observations performed recently on silica aerogels are reviewed.

As discussed above, such a hump is not an intrinsic feature of the fracton model. It is also not a specific feature of glasses, since good single crystals often show such a hump, e.g. W.N. Lawless, Phys. Rev. B 14, 134 (1976). In fact, humps of comparable size are found in fused silica and in crystalline quartz.26
