    Abstract

    This paper describes measurements made on a system of two rooms separated by a wall but connected by a ventilation duct. Using statistical energy analysis the noise reduction of each path through the system was determined from the measured data. It was found that the most important path through the system is from the source room, into the duct cavity, along the duct and then out into the receiving room. Experiments on air flow showed that for practical purposes air flow has no effect on the system considered here. © 1979.
