'it enhances sounds' is the definition.
The definition suggests a singular noun which matches the answer.

'european skill behind film' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'skill' becomes 'art' (both can mean a talent).
'behind' becomes 'rump' (informal term for the buttocks).
'film' becomes 'ET' (E.T. the Extra-Terrestrial).
'e'+'art'+'rump'+'et'='EAR-TRUMPET'
