Instrument making familiar sound (4)
I believe the answer is:
bell
This could be a double definition.
'instrument making familiar' is the first definition.
'bell' can be an answer for 'instrument' (I have seen 'Musical instrument ' mean 'bell' so perhaps 'instrument' could also mean 'bell'). I'm unsure of the 'making familiar' bit.
'sound' is the second definition.
(I know that bell is a type of sound)
Can you help me to learn more?
(Other definitions for bell that I've seen before include "Wide end of a trumpet" , "Boxing match signal" , "Something to jingle?" , "The frigate Lutine's hangs in Lloyd's of London" , "Metal ringer" .)
