Aged deterioration of social infrastructures such as concrete tunnels has become a serious problem. For safety and security, reliable inspection of them is highly demanded. Hammering test is one of efficient inspection methods. However, the inspection task needs a lot of expert workers. In this paper, a methodology of constructing a hammering-inspection-based defect detector that can be applicable to concrete structures is proposed. Furthermore, the diagnosis process based on a new boosting algorithm is visualized for the purpose of supporting reliable inspection. The proposed defect detector was applied to signals obtained in a real inspection site of a concrete tunnel.
