Sound effect in an empty hallway (4)

I believe the answer is:

echo

(Other definitions for echo that I've seen before include "Rebounding sound" , "Reiterate" , "Let's hear it again for the Greek nymph who loved Narcissus in vain" , "Reflection of sound waves" , "Nymph (only able to repeat the last words of others)" .)

I've seen this clue in the USA Today.
