Abstract
The architectural product industry demonstrates sound transmission loss performance by commissioning third party tests from accredited laboratories performed according to the ASTM E90 standard. This presentation will provide insight into the materials testing process, laboratory quality management, and explanation of the report documents. The presenter will share experience and advice for the use of test results to evaluate acoustical product performance. Acousticians, architects, and engineers must play a role in improving quality of published data by demanding more complete information from manufacturer's marketing departments regarding product acoustical performance.
