The house prototype of the Provisional Emergency House System uses wood and its derivatives for the facades, floor structure, roofing and partitions. The extensive use of wooden panels for the construction and the lack of data, in Spain, about their acoustic behavior bring up the necessity to make in situ measurements of the acoustic isolation to airborne sound.
Panels used for facades and partitions are built with a wooden framework and membrane of oriented strand board in both sides, for the facades, and of laminated plaster boards for the inner partitions.
With the objective of verifying the sound insulation of the facades according to Spanish Standard UNE EN ISO 140-5, in situ measurements of airborne sound insulation of facade elements and facades have been made; according to Spanish Standard UNE EN ISO 140-4, in situ measurements of airborne sound insulation between rooms for internal walls have also been made. The procedure of the global insulation has been followed to measure the acoustic insulation of complete facades without making distinction between the elements that form it.
