Talks conveying a lot of sound lines (9)

I believe the answer is:

ordinates

'lines' is the definition.
(as in one half of a co-ordinate)

'talks conveying a lot of sound' is the wordplay.
'talks' becomes 'orates' (orating is a kind of talking).
'conveying' is an insertion indicator.
'a lot of sound' becomes 'din' (din can mean a loud disturbance).
'orates' placed around 'din' is 'ORDINATES'.

I've seen this clue in The Times.
