    Acoustic emission due to crack growth in a solid material under stress. Leaks, friction, knocks, chemical reactions, changes of size of magnetic domains are other examples of sources generating acoustic emission waves.

    A complete guide to Acoustic emission testing for your consideration.

    Acoustic emission testing (AET) is a non-destructive testing (NDT) technique that detects flaws in objects by monitoring the pattern of ultrasonic stress waves within structures and materials through an attached set of AE sensors. These AE sensors will convert the stress waves into electrical signals and relay those signals to an external equipment/device for processing.

    Acoustic emission testing, or acoustic emission monitoring, uses sound waves to detect and locate defects in structures and materials. It is often used in the manufacturing and construction industries to detect cracks, flaws, corrosion, and other defects.

    Acoustic emission testing is also called Acoustic Emission (AE), Acoustic Testing (AT), Acoustic NDT, or AE Testing.

    Acoustic emission testing is one of the most common and useful methods of non-destructive testing (i.e., testing that allows inspectors to collect data on materials without harming them).

    The primary advantages of acoustic emission testing are that it allows inspectors to test a material’s entire load history without damaging it.

    Historically, AE has been used only for inspecting and maintaining expensive structures due to the high costs associated with it. But new developments have helped lower the cost of AE equipment, and it is becoming more accessible for a host of inspection applications.
