Harsh and loud (7)
I believe the answer is:
raucous
'harsh and loud' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for raucous that I've seen before include "Rowdy - strident" , "Harsh in sound" , "Noisy and harsh-sounding" , "Unpleasantly noisy" , "Harsh, strident" .)
