โฆ Synopsis
This paper describes the design, construction and perJormance of a test Jacility Jor transmission loss measurement. The receiving portion of the jacility consists oJ a 118 m 3 reverberation room, while the source room is a 1.0 m 3 pit with high sound insulation. The partition being measured makes up the top of the pit. A series oJ measurements concerning the perlormance of the test Jaeilio, are presented and discussed.
