Abstract (in Japanese) (See Japanese page) 
(in English) In the non-contact acoustic inspection method, we have developed the non-contact method to measure defects such as a crack near the surface of the concrete structure from a distance using air-borne sound and have devised a defect detection algorithm. This time, using a reinforced concrete specimen in which the degree of the reinforcing rod corrosion was different, we have tried to visualize a defect to be spread in the surface from inside. We have investigated whether strength estimation of concrete was possible using a concrete specimen in which some cylinder concrete of the different strength was embedded.
