Working with sound, throwing a lot of noise about (5)
I believe the answer is:
sonic
'working with sound' is the definition.
I can't tell whether this definition defines the answer.
'throwing a lot of noise about' is the wordplay.
'throwing' indicates an anagram (letters get thrown around).
'a lot of' means to remove the last letter (most of the word but not all of it).
'about' becomes 'c' (abbreviation for 'circa').
'noise' with its last letter taken away is 'nois'.
'nois' anagrammed gives 'soni'.
'soni'+'c'='SONIC'
Can you help me to learn more?
(Other definitions for sonic that I've seen before include "seven hundred and forty three mph!" , "Hedgehog" , "Boom of jet aircraft" , "Sort of boom" , "Using waves" .)
