As there's a bit of noise about, you need somewhere nice and deserted (5)
I believe the answer is:
oasis
'somewhere nice and deserted' is the definition.
I can't tell whether this defines the answer.
'as there's a bit of noise about' is the wordplay.
'there's a bit of noise' becomes 'ois' (I can't justify this - if you can you should give a lot more credence to this answer).
'about' means one lot of letters goes inside another.
'as' put within 'ois' is 'OASIS'.
'you need' acts as a link.
Can you help me to learn more?
(Other definitions for oasis that I've seen before include "Desert sanctuary" , "Britpop group" , "Band with Liam and Noel Gallagher" , "Peaceful area away from trouble" , "source of water" .)
