Second, perhaps, to have spoken about loud noise (7)
I believe the answer is:
ordinal
'second perhaps' is the definition.
(second is an example)
'spoken about loud noise' is the wordplay.
'spoken' becomes 'oral' ('oral' can be similar in meaning to 'spoken').
'about' indicates putting letters inside.
'loud noise' becomes 'din' (I've seen this before).
'oral' going around 'din' is 'ORDINAL'.
'to have' acts as a link.
(Other definitions for ordinal that I've seen before include "Relating to series order" , "Eg second" , "Numeral indicating rank order" , "Number defining a thing's position in series" , "Ninth, maybe" .)
