1. A system comprising:
an acoustic exciter configured for triggering acoustic excitation of at least part of a substrate, the acoustic exciter including a circumferential band around a rotating element;
a sensor configured to receive an acoustic response of the acoustic excitation;
circuitry configured to determine at least one characteristic of the substrate using the acoustic response,
the system being configured to be attached to a vehicle for traversing the substrate with the acoustic exciter,
the acoustic exciter being included in a plurality of acoustic exciters; and
cross ties to which the circumferential band is coupled.
