One day a jazz man starts to introduce very explosive sound (9)

I believe the answer is:

fricative

'sound' is the definition.
(fricative is a kind of sound)

'one day a jazz man starts to introduce very explosive' is the wordplay.
'one day' becomes 'fri' (abbreviation for Friday).
'a jazz man' becomes 'cat' (I've seen this in another clue).
'starts to' indicates taking the first letters.
The initial letters of 'introduce very explosive' is 'ive'.
'fri'+'cat'+'ive'='FRICATIVE'

(Another definition for fricative that I've seen is " Stinging arachnid".)

I've seen this clue in the Sydney Morning Herald.
