ACOUSTIC TESTING SERVICES FOR WINDOWS, DOORS, AND BUILDING PARTITIONS A Fenestration Test Being Performed in an ETS-Lindgren Reverberation Chamber SCAN TO SEE A FENESTRATION TEST.

WHY YOU NEED TO TEST IMPROVE PERFORMANCE, REDUCE COST Testing windows, doors and partitions for their acoustic properties can lead to performance improvements while reducing manufacturing costs. Architects (and the clients they serve) often specify that windows, doors, etc. meet a Sound Transmission Class (STC) rating that originates from data obtained during ASTM E90 testing. The test is best performed in a professional laboratory. Some manufacturers see testing as an expense, and overdesign their products as a result. This can add unnecessary cost – especially when hundreds or thousands of...
