If a metal plate has a resonant frequency of 100hz when struck by an object (creating an impulse) it rings at 100hz.
If the plate was subjected to a 99hz vibration would it ring at 99hz at a lesser amplitude or its resonant 100hz, assuming the Q of the plate was failry wide.
Looking at an old fashoned frequency meter that uses tuning forks I'd say the former.
