I believe the answer is:

raucous

I'm a little stuck... Click here to teach me more about this clue!

'strident' is the definition.
(I know that strident can be written as raucous)

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for raucous that I've seen before include "Unpleasantly loud and harsh" , "Harsh, strident" , "Rowdy - strident" , "Harsh, noisy" , "Rough and discordant" .)

I've seen this clue in The Telegraph.
