peep

'little noise' is the definition.
The definition and answer can be both related to natural events as well as being singular nouns.
Maybe there's a link between them I don't understand?

'go quiet' is the wordplay.
'go' becomes 'pee' (both can mean to urinate).
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'pee'+'p'='PEEP'

'making' is the link.

Can you help me to learn more?

(Other definitions for peep that I've seen before include "Secret look" , "Look quickly" , "Spy" , "Look furtively or voyeuristically" , "Look furtively (either way)" .)
