Wyatt to draw noise abatement device (7)
I believe the answer is:
earplug
'noise abatement device' is the definition.
The definition suggests a singular noun which matches the answer.
'wyatt to draw' is the wordplay.
'wyatt' becomes 'earp' (I've seen this before).
'to draw' becomes 'lug' (I can't justify this - if you can you should give a lot more credence to this answer).
'earp'+'lug'='EARPLUG'
Can you help me to learn more?
(Other definitions for earplug that I've seen before include "Protection against noise" , "Lug stopper?" , "Noise excluder" , "Noise defender" , "It blocks out sound" .)
