Testing hearing (6)

Ross

I believe the answer is:

trying

I believe this is a double definition.

'testing' is the first definition.
('try' can be a synonym of 'test')

'hearing' is the second definition.
('try' can be a synonym of 'hear')

(Other definitions for trying that I've seen before include "Stressful" , "Making attempts" , "Tiresome" , "responsibility of the first Baron Jeffreys of Wem" , "Exasperating" .)

I've seen this clue in The Telegraph and The Guardian.
