Let siren damage ear, perhaps (8)
I believe the answer is:
'ear perhaps' is the definition.
I can't judge whether this defines the answer.
'let siren damage' is the wordplay.
'damage' indicates an anagram (I've seen 'damaged' mean this).
'letsiren' anagrammed gives 'LISTENER'.
Can you help me to learn more?
(Other definitions for listener that I've seen before include "One enjoying radio broadcast", "One paying attention", "Puzzle", "One trying to hear", "Difficult Times Saturday crossword".)
