SCHAUMBURG, Ill. – AAMA 1801-08, a voluntary specification for acoustical testing, has been released by the American Architectural Manufacturers Association (AAMA). According to Ken Brenden, AAMA technical standards manager, the revamped eight-page document, first published in 1995 and titled Voluntary Specification for the Acoustical Rating of Windows, Doors and Glazed Wall Sections, includes several updates.

The test specification describes the sound transmission loss measurement procedure for windows, doors and glazed wall sections.

“In addition to various editorial changes, the most significant changes were the addition of new sections 6.0, Test Specimen Installation and 7.0, Conditioning,” states Brenden. “New sub-sections under Test Reports were also added addressing the verification of the manufacturer’s statement, filler wall transmission loss and items to include in the detailed description of the glazing material.”

In addition, a reference to ASTM E 90 Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements was added, as well as a diagram detailing test specimen installation, according to Brenden.
