Stage performers arrive: audience primarily enthralled by loud noises (9)

'stage performers' is the definition.
'comedians' can be an answer for 'performers' (comedian is a kind of performer). I'm unsure of the 'stage' bit.

'arrive audience primarily enthralled by loud noises' is the wordplay.
'arrive' becomes 'come' (synonyms).
'primarily' says to take the initial letters.
'enthralled by' is an insertion indicator ('enthral' can mean 'capture').
'loud noises' becomes 'dins' (I've seen this in another clue).
The first letter of 'audience' is 'a'.
'a' put into 'dins' is 'dians'.
'come'+'dians'='COMEDIANS'
