Limitations

• The equipment costs are high
• The method requires means of loading the structure and complex electronic equipment
• Environments are generally very noisy, and the AE signals are usually very weak thus, signal discrimination and noise reduction are very difficult, yet extremely important for successful AE applications
• Extensive Knowledge is required to plan the test and to interpret the results
