In context

Ultrasonic means relating to or using very high sound waves.
The wheel shop also has equipment for ultrasonic testing of axles for flaws; and systematic checking of locomotive axles and crank pins is carried out as they pass through the shops.
When an ultrasonic beam is fired at the microcannons, the emulsion evaporates, expanding rapidly into gas. This creates enough force to push the nanobullets out at velocities reaching several metres per second.
