A review of unconventional sustainable building insulation ...

Since acoustic properties depend on frequency, direct comparisons, as those made for thermal properties, cannot be easily performed. Moreover sound insulation of a double wall depends on all its elements and not only on the insulation material. Nevertheless some interesting results can be presented.
