Buzz-o-sonic is a Nondestructive tester for measuring elastic and damping properties and the structural integrity of materials used in R&D, QA and QC. Buzz-o-sonic uses the Impulse Excitation Technique (IET) or Ping Test as described in ASTM E1876 and C1259 to determine the elastic properties of materials. In this test, an object is tapped lightly with a special hammer (impulse tool) and the resulting vibrations-natural or resonant frequencies - are measured.
