Range for picking up others? (7)

I believe the answer is:

earshot

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

'range' is the definition.
(I know that earshot is a type of range)

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for earshot that I've seen before include "Hot ears (anag.)" , "Range for hearing" , "Hearing distance" , "in audible range" , "Distance within which a sound can be heard" .)

I've seen this clue in The Guardian.
