A series of acoustic tests were performed on a proposed roof construction for a new concert hall at The University of North Texas to evaluate its sound transmission loss properties. The test was conducted to determine if the wood and metal deck construction would be sufficient to isolate nearby highway traffic noise (airborne) and heavy rain and hail noise (structure-borne) from being heard in the concert hall. Four variations of the roof system were constructed and tested to determine the range of possible solutions. Simulation of rain and hail noise test methods and results are presented along with standard ASTM E-90 results and the recommended solution.
