The four main application categories are Acoustic Testing, Rotating Machinery Diagnostics, Structural Testing, and Vibration and Shaker Testing.

After a hiatus, the trio reunited and toured continuously.

The exception to this may be if there are other acoustic-sensitive tests going on in adjacent rooms.

Beginning with functional testing, the mechanical test program (vibration and acoustic testing) will take place at NASA's Goddard Space Flight Centre (GSFC).
