Riverbank Acoustical Laboratories (RAL) is a NVLAP accredited ISO 17025 laboratory that specializes in acoustical testing for prominent architectural product manufacturers and government agencies. RAL provides sound absorption, sound transmission loss, and sound power ratings trusted by acoustical engineers around the world.
NVLAP Accredited Acoustical Testing Services Include:
Riverbank Acoustical Laboratories (RAL) was built by Colonel George Fabyan for Wallace Clement Sabine in 1918. The test chamber dimensions, construction materials, and isolation specifications were carefully engineered by Dr. Sabine.
After Wallace Clement Sabine passed away in 1919, the task of managing laboratory operations was granted to Paul Sabine, who refined the test methods and developed RAL into a successful business. After Paul retired, the lab operations were handed to Hale Sabine and the Armour Research Foundation of the Illinois Institute of Technology. The Armour Research Foundation (ARF) was renamed IITRI in 1963. IITRI funded a large enhancement to the RAL operation in the 1960's, which included a new Transmission Loss facility.
In 2002, the technology and engineering divisions of IITRI (including RAL) were formed into a new company named Alion Science and Technology. Today, Alion maintains a NVLAP accredited testing operation in the Riverbank facility for prominent acoustical material manufacturers and government agencies.
