Hopkins reported on the remit* of eound attenuating test* on 1ead coivlucted by the British Non-ferrous Metals Beeearcfc Association which are only to the neclere of that group. Ke stated how- erar that the teirte confine tho result* achieved by The Broken Kill Associated Saelter* Ply. Ltd. end that they war* Bade in accordance with the requiraBente of British Standard Specifications oryanication. Unfortunately, be pointed out, the teete ware conducted on leaded plywood and plywood la not generally permitted in the United States for fireproof construction. A trend against the ns* of plywood for such construction la underway in Australia. Kr. Kopidns further reported that hie ocnpany la working closely with aa Australian panel Bars; facturer la an atteept to develop a panel that would Incorpo rate a free hanging 2-lb. lead efcee*. scqa-^'s a fM/W Mr. Oaut.echl then repotted on hie company'* adivltiee aa per EdilMt "A" attached. QM8 Kr. Taylor then reported that as a result of Investigations he has con ducted, the ais; of this research should be for a wall that would provide a tranemission lose of 50 db. Also that euch a wall should be of grin'gg^ thickneae, perhaps 2 in. or slightly acre. He pointed out that there is considerable Interest in dry-wall construction and that it le being used in many high-rise apartments. Such nils, be stated, are generally 1-1/9 In. thick with an open air apace In the center end that they hare a transclesioa loss rating of 16 db. Lead could possibly be incorporated in such tells to cut down overall thickness and still provide a competitive transmission lose figure. The chalroan then briefly reviewed the situation and suggested an order of priority on the various aspects of lead for sound attenuation. He suggested the following order of priority with thich the Ooeadttee agreed; 1. Celling Tile Applications 2. Movable Partitions 3. Dry-Kail Construction Cslllnr Tile Applicable-.*: It was pointed out that the results of Goodfrland'a vzm with 1 lb. sheet lead over ceiling tiles indicate that thare Bay be a *1sable Darxet for lead in this crca.
