About the noise - it will echo (7)
I believe the answer is:
resound
'echo' is the definition.
(I know that echo can be written as resound)
'about the noise' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'the noise' becomes 'sound' (I've seen this before).
're'+'sound'='RESOUND'
'it will' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for resound that I've seen before include "Reverberate" , "Echo" , "ring" .)
