# Ultrasonic testing ## Overview Nondestructive testing (NDT) method using sound waves to detect flaws. ## Acoustics bridge NDT, chatter control on the spindle ## Hub connections ### Engineering Center of Excellence Secondary acoustic application context (to be developed). ### Advanced Manufacturing Center of Excellence (primary) This article bridges [[PORTAL_Acoustics]] to the [[WT!Advanced_Manufacturing_Center_of_Excellence]]. The acoustic signature of ultrasonic testing is central to advanced manufacturing operations. ### Transportation Center of Excellence Secondary acoustic application context (to be developed). ### Energy Center of Excellence Secondary acoustic application context (to be developed). ### IT Center of Excellence Secondary acoustic application context (to be developed). ### HealthForce Center of Excellence Secondary acoustic application context (to be developed). ### Northern Agricultural Center of Excellence Secondary acoustic application context (to be developed). ### Southern Agricultural Center of Excellence Secondary acoustic application context (to be developed). ### Space Mining In Minnesota — Center Circle Secondary acoustic application context (to be developed). --- *Bridge article, scaffolded from [[PORTAL_Acoustics]].
