Abstract
A method and apparatus for inspecting a composite structure. A response sound signal to a sound signal sent into the composite structure at a location on the composite structure is detected. An attenuation is identified in the response sound signal detected in response to the sound signal sent into the composite structure at the location on the composite structure. An indication of whether additional evaluation of the location is needed based on a comparison of the attenuation in the response sound signal to a baseline attenuation value for porosity for the location on the composite structure is generated.
