✦ 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.
