Noise from family gathering at the outset (5)
I believe the answer is:
clang
'noise' is the definition.
(clang is a kind of noise)
'family gathering at the outset' is the wordplay.
'family' becomes 'clan' (I've seen this before).
'at the outset' suggests taking the first letters.
The first letter of 'gathering' is 'g'.
'clan'+'g'='CLANG'
'from' acts as a link.
(Other definitions for clang that I've seen before include "Noise from crane" , "Noise as of cymbals" , "Harsh cry" , "Resounding effect" , "Ring like a bell" .)
