Element’s acoustic noise testing experts compile and analyze the data generated in our high-intensity testing chamber, and provide critical information and analyses to clients in aerospace, military, and defense industries.

Computer-controlled acoustic noise is generated through a digital closed loop control system using three high power microphones as feedback. Depending on the testing standard, 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.

Our high-level acoustic noise testing capabilities

Element’s acoustic testing experts have years of experience designing and supporting a wide array of test plans. Our acoustic noise lab can help you meet your military acoustic testing specifications, such as MIL-STD-810, Method 515 and MIL-STD-1373D (previously MIL-STD-740).

We test to a wide range of industry standards, including: 

    • ISO 9296
    • ISO 7779
    • ISO 3744
    • GR-63-CORE
    • ETSI EN 300 753
    • IEC 60601

If your project requires custom or complex set ups, we can assist in creating unique test plans that will ensure product safety and durability while meeting your program requirements. 

Highly Reverberant Chamber 640 x 480

Reverberant chambers for high level acoustic noise testing

Reverberant chambers are used to test the acoustic noise of large aerospace and other industrial components at intense levels of sound pressure.

In our high level acoustic noise testing 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
    • Meeting military specs, including MIL-STD-810 and MIL-STD-1474D (previously MIL-STD-740)
    • Other acoustic test specifications required for military and defense equipment
