We used two acoustic measurement systems to assess the state of a quay wall. Collapse and subsidence of quay walls at harbors are often reported, and the development of a diagnostic method to help prevent collapse has become a significant concern. Collapse normally occurs because of an air hole inside the quay wall. Therefore, a robust, accurate diagnostic system to detect air holes is required. Hence,...
