Carpets are being ruined by parties (9)

I believe the answer is:

earbashes

I'm a little stuck... Click here to teach me more about this clue!

'carpets' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'are being ruined by parties' is the wordplay.
'being ruined' indicates an anagram.
'by' is a charade indicator (letters next to each other).
'parties' becomes 'bashes' (bash is a kind of party).
'are' is an anagram of 'ear'.
'ear'+'bashes'='EARBASHES'

Can you help me to learn more?
