Abstract
Riverbank Acoustical Laboratories (RAL) is located in Geneva, Illinois. Constructed in 1918, RAL became the world’s first independent laboratory dedicated to the science of architectural acoustics. Riverbank owner, philanthropist Colonel George Fabyan, built the laboratory for its designer, professor Wallace Clement Sabine. The scientific efforts of this renowned Harvard physicist earned him two distinguished titles, acknowledged today as the father of the science of architectural acoustics and the first ‘‘modern day’’ acoustical consultant. The unit of absorption is a Sabin. When the professor died in 1919, his distant cousin, Dr. Paul Earls Sabine, became RAL’s director. Retired in 1947, Dr. Sabine turned the operations over to the IIT Research Institute. RAL provides a wide range of acoustical testing services for over 600 clients. The majority of RAL tests are industrial related. RAL provides clients with an accredited, independent testing facility, not associated with any manufacturer or product. Part of RAL’s outstanding credibility reflects upon their policies of maintaining strict confidence and proprietary rights for all clients. RAL is accredited by NVLAP, The City of Los Angeles, and others. Also of interest to many clients is RAL’s museum dedicated to the Science of Architectural Acoustics. The ASA officially sanctioned the museum in 1989.
