β¦ Synopsis
A BSTRA CT
A number of different designs for sound transmission suites are examined and their performance computed for standard walls. It is found that the performance of the system depends on both the test wall and the design of the chambers. Even when panels are placed over the walls to eliminate radiation the chambers will still influence the overall performance.

A total of 390 measurements of ventilation rates has been made in seven closed rooms of six houses, using nitrous oxide as the tracer gas. The houses are located in outer suburbs of Melbourne. Half of the observations were taken when the wall ventilators were sealed, in order to explore the influenc
This study assessed the fire risk of attaching a qualified surface wall lining to an unqualified combustible substrate. Experimental materials were gypsum, magnesium oxide, calcium silicate board and fire-retardant plywood, which were attached to a non-fire-retardant plywood panel. The CNS 6532 Surf
