Quiet road? The reverse - it's noisy (4)

I believe the answer is:

yawp

'it's noisy' is the definition.
(type of cry or shout)

'quiet road? the reverse' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano').
'road?' becomes 'way' (I've seen this in other clues).
'the reverse' is a reversal indicator.
'p'+'way'='pway'
'pway' in reverse letter order is 'YAWP'.

(Another definition for yawp that I've seen is " harsh cry".)

I've seen this clue in The Telegraph.
