Sports bats suppress noises (6,7)
I believe the answer is:
squash rackets
'sports bats' is the definition.
'squash rackets' can be an answer for 'bats' ('squash racket' can be a synonym of 'bat'). I'm unsure of the 'sports' bit.
'suppress noises' is the wordplay.
'suppress' becomes 'squash' (I've seen this in another clue).
'noises' becomes 'rackets' (racketing is a kind of noising).
'squash'+'rackets'='SQUASH RACKETS'
Can you help me to learn more?
(Other definitions for squash rackets that I've seen before include "Court action" , "sport" , "they'll be needed in court" , "Game" , "put an end to fraudulent schemes" .)
