Element, in conjunction with NASA, designed and constructed a high intensity, High-Level Acoustic Noise Reverberant Facility in their Jupiter, Florida laboratory. The pentagonal reverberant chamber, coupled to high-output electrodynamic acoustic drivers, delivers a uniform acoustic noise spectrum over the entire frequency range. High-intensity noise is generated via two high power acoustic transducers. The facility is unique for acoustic noise testing of full-size aerospace and other industrial components at high levels of sound pressure.
Providing acoustic testing data to aerospace and defense industries
The acoustic noise generated is computer controlled through a digital closed loop control system using three high power microphones as the feedback. Data can be analyzed in 1/3 or 1/6 octave frequency bands. Microphones can be analyzed separately or averaged for differently-sized test units or control strategies.
Reverberant chambers for equipment and component acoustic noise testing
In the Florida acoustic noise lab, noise spectra in the reverberant chambers have been shaped to match acoustic emissions from defense and military sources, including:
- Space Shuttle launch noise specifications
- Rocket launch noise specifications
- Aircraft structural excitation noise
- Aerospace engine noise and engine nacelle noise
- Unsteady turbulent airflow noise
- Other acoustic test specifications required for military and defense equipment.
Meeting military specs
Element acoustic testing experts compile and analyze the data generated in its High Level Acoustic Noise Reverberant Facility, and provide critical information and analyses to clients in aerospace, military, and defense industries. Our acoustic noise lab can help you meet your military acoustic testing specifications, such as MIL-STD-810, Method 515, "Environmental Engineering Considerations and Laboratory Tests: Acoustical Noise (Suppression & Performance)." MIL-STD-810 Method 515 is just one of many acoustic noise evaluation standards we can support.
