The century old Riverbank Acoustical Laboratories, an Alion laboratory, continues to be the leader in certified acoustics testing.

In 1912, on Colonel Fabyan’s Riverbank Estate in Geneva, Ill., an acoustic levitation device was constructed from instructions discovered in an old book. After several failed attempts to make the device fly, Fabyan finally asked acoustics expert and Harvard Professor, Wallace Clement Sabine to examine the situation. Professor Sabine quickly debunked the acoustic levitation device as a hoax, but convinced the grateful Colonel to construct on the estate the world’s first scientific acoustics testing laboratory; Riverbank Acoustical Laboratories.
