What Is Acoustic Emission Testing (AE)?

Acoustic Emission Testing is a nondestructive testing method that detects transient elastic waves generated by sudden energy releases within materials or structures.

These waves may be produced by active processes such as crack growth, plastic deformation, fiber breakage, and certain leakage mechanisms.

AE sensors detect the resulting signals, which are processed and analyzed to evaluate structural activity and identify potential areas of concern.

Unlike many conventional NDT methods that inspect specific locations for existing discontinuities, acoustic emission testing is particularly useful for monitoring active damage mechanisms while a component is subjected to operating loads or controlled testing conditions.

Common industrial applications include:

  • Pressure vessels and storage tanks

  • Pipelines and pressurized systems

  • Bridges and civil infrastructure

  • Composite and fiberglass-reinforced structures

  • Aerospace and automotive components

  • Structural health monitoring

  • Industrial machinery and equipment

Acoustic emission testing is especially valuable for large-scale monitoring. However, it may not detect dormant defects that produce no acoustic activity, and other NDT techniques may be required for further characterization.

How to Prepare for the ASNT AE Level III Examination

Passing an advanced NDT examination requires more than memorizing definitions. Candidates should understand both the theoretical principles and their application to real inspection scenarios.

Follow these preparation steps:

  1. Study the official examination outline. Review the published ASNT AE Level III topics and identify areas requiring additional preparation.

  2. Review Acoustic Emission fundamentals. Focus on wave propagation, sensor response, attenuation, instrumentation, and signal analysis.

  3. Practice numerical questions. Work through calculations involving wave velocity, arrival time, source location, decibels, and other applicable AE parameters.

  4. Study testing procedures and standards. Understand calibration requirements, equipment setup, inspection procedures, and reporting.

  5. Attempt practice examinations. Take multiple-choice quizzes to become familiar with examination-style questions and time management.

  6. Review incorrect answers. Identify weak topics and revisit relevant study materials before repeating the practice test.

Candidates preparing for the NDT Basic examination should also review applicable ASNT qualification and certification documents.

For Basic exams taken after January 1, 2026, ASNT’s recommended references incorporate the 2024 editions of SNT-TC-1A and CP-189, replacing the previously referenced 2020 editions.
