Zusammenfassung:	An acoustic diagnostic method for detecting structural degradation includes steps as follows: first, a deep neural networks is used to construct a training model. At least two training acoustic signals are inputted into the training model to carry a training. A diagnostic model is built based on a result of the training and a convolutional neural networks. An under test sound wave signal is extracted from an under test structure section by direct contact, non-contact, or indirect contact. The structural deterioration state of the under test structure section is determined according to the under test sound wave signal using the diagnosis model.
