Riverbank Acoustical Laboratories , ''', is a NVLAP accredited acoustical testing agency founded by George Fabyan in 1913. The testing service remains a highly respected source of independent acoustical materials testing. RAL specializes in STC, NRC, IIC, and Sound Power testing. The current address for the company is 1512 Batavia Ave. Geneva, IL. This location also houses the Riverbank Acoustical Museum and Acoustical Library.
History
The acoustical laboratory building was funded and built by Colonel George Fabyan on his vast Riverbank Estate in Geneva, Illinois. Colonel Fabyan was a patron of obscure sciences, and references to his "Riverbank laboratories" exist as early as 1916. In 1913, Fabyan hired Wallace Clement Sabine to help tune an acoustical levitation machine built according to specifications decoded from a Sir Francis Bacon work. Sabine ultimately convinced the colonel that the machine would never work, and the two became close friends. After hearing Sabine's complaints of the poor conditions of his acoustical test lab at Harvard, Colonel Fabyan agreed to build a state of the artreverberation chamber and test facility for Sabine to use on the property. Sabine died in 1919, shortly after the lab was constructed. The task of managing the Laboratory Operations was granted to his cousin, Paul Sabine, who refined the test methods and developed the lab 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 was renamed IITRI in 1963. IITRI funded a large expansion to the laboratory in the 1960s, which included a new transmission loss facility. In 2002, the technology and engineering divisions of IITRI were spun off into a new company named Alion Science and Technology. Today, Alion conducts advanced acoustical testing operations in the facility for many prominent acoustical material manufacturers and government agencies. In the facility's early days, it also housed a cryptology team that worked to decipher codes from the works of Sir Francis Bacon, Shakespeare, and enemy military communications. Fabyan allowed the U.S. Government to use Riverbank Laboratories to their disposal during World War I and the estate played an instrumental role in history for deciphering the German and Mexican code. Quite a bit more occurred in the area of cryptanalysis done by William and Elizebeth Friedman. In 1993, the National Security Agency recognized the work with a plaque reading "To the Memory of George Fabyan From a Grateful Government: In recognition of the voluntary and confidential service rendered by Colonel Fabyan and his Riverbank Laboratories in the sensitive areas of cryptanalysis and cryptologic training during a critical time of national need on the eve of America's entry into World War I." The building is recognized in the National Register of Historic Places.
