'an anti-noise demonstration?' is the definition.
I can't tell whether this defines the answer.

'noise demonstration?' is the wordplay.
'noise' becomes 'silent' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'demonstration?' becomes 'protest' (demonstration is a kind of protest).
'silent'+'protest'='SILENT PROTEST'
