Acoustic Vibration Test Systems

Mark VI.2 Acoustic Generator

Team Corporation has been involved with the design, manufacture, application and installation of acoustic generators for more than 40 years. Team’s acoustic generator is the result of many years of design experience and the evolutionary development of an original acoustic generator patented by the Aircraft Division of Northrop Corporation. Team worked with Northrop as a supplier and subcontractor from the inception until it acquired the patent in 1973.
Acoustic chamber testing is used

to duplicate the noise environment witnessed by components and subassemblies in aeronautical and space vehicle applications. For instance, the noise from a jet engine can acoustically couple high frequency energy into underwing munitions assemblies or the high acoustic energy rocket engines generate can induce stress in shuttle bay mounted components. Addition of a single or multi-axis vibration test system can realistically duplicate the acoustic and acceleration environments of these high-energy locations in the laboratory.


The Mark VI.2 Acoustic Generator consists of a servo-hydraulic actuator driving a specialized reciprocating poppet valve that provides modulation of a high-pressure airstream. This design has proven to be the most effective sound source for large reverberant and progressive wave tube test chambers, providing extreme power handling capabilities with high efficiency. Peak acoustic pressures of approximately 60% of the supply pressure are produced downstream of the poppet valve.
