What is “undamped vibration absorption” ?

What is “undamped vibration absorption” and how would you use this
concept to absorb the vibration of a un-damped, simple mass spring
system of mass m and stiffness k oscillating at its resonance frequency?

Hi.
A can't decide what the expression means. Absorption really implies some form of damping or energy loss. What is the context?
