Acoustical Testing Laboratories - Architectural Products

W. C. Sabine established the Riverbank Acoustical Laboratory near Chicago for acoustical research and testing.  The tests of sound transmission and absorption developed there have evolved into a series of ASTM standards.  The most commonly used laboratory standards in North America are ASTM C423 for sound absorption and ASTM E90 for sound transmission loss.  Other laboratories have been built modeled after Riverbank.  Some are independent.  However, many are operated by companies that make products with acoustical properties.  They use the laboratories to test their products and some offer testing services to others.  These laboratories have large rooms with hard walls.  There is a very heavy wall between a pair of rooms with an opening to test the sound transmission of walls, doors, or other panels. Laboratories should be accredited by the National Voluntary Laboratory Accreditation Program of the U. S. Department of Commerce and most of the following are.  Some are accredited by other organizations which do not have such specific acoustic requirements.  The following laboratories offer testing by ASTM C423 and ASTM E90.
