Sound made by a worn receiver (5)
I believe the answer is:
bleep
'sound' is the definition.
(I know that bleep is a type of sound)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bleep that I've seen before include "Sharp electronic sound" , "Electronic sound (used over profanities)" , "High-pitched signal from device - you're needed" , "Page" , "Swearing substitute" .)
