Abstract	In today’s economy, structures must remain in operation for much longer periods of time than originally anticipated. The aging effects on these structures are becoming significant and must be accounted for in the decisions made regarding usage, maintenance, and retirement of these structures. The development of nondestructive testing techniques to monitor the condition of these structures is very active and these developments are focused on extending the remaining lives and/or reducing the costs of maintenance of existing structures. A fast, accurate and cost-effective method of structural monitoring that has shown to be very reliable, and can inspect both ‘locally’ and ‘globally’, is acoustic emission (AE) and acousto-ultrasonics (AU). AE/AU technology can detect structural defects long before possible catastrophic failures. Complementing other NDT testing methods, AE/AU has proven to be a reliable and ‘sound’ technology for structural health monitoring within a predictive maintenance program. This is possible because discontinuities will produce detectable emissions, long before structural integrity is compromised and structural failure occurs. Acoustic emission and acousto-ultrasonics technology can be applied to many of today’s ageing structure problems, ranging from structural health monitoring in the aerospace industry, to locating discontinuities in hybrid composite structures for active flaws. This paper will examine this technology and discuss several applications and monitoring scenarios.
