    I have a problem with the owner above my unit replacing the heavy, sound insulating carpet originally installed, with timber flooring. The timber floor was glued directly to the concrete floor slab, with no underlay or insulating layer.
    I have derived a lot of useful information from your page “Timber and Tiled Floors”, dated 09/01/2010. One useful piece was a document “Acoustic-Ratings-Floors” giving comparisons between the acoustic properties of different floor treatments.
    Can you tell me the derivation of this document please? There’s a note at the bottom of Table 1 about the Association of Australian Acoustical Consultants (AAAC). Did it come from them?
