Lowering sound, crooner admits hint of laryngitis (8)

I believe the answer is:

humbling

'lowering' is the definition.
(humble can mean to lower someone)

'sound crooner admits hint of laryngitis' is the wordplay.
'sound' becomes 'hum' (humming is a kind of sounding).
'crooner' becomes 'Bing' (Bing Crosby).
'admits' means one lot of letters goes inside another.
'hint of' says to take the initial letters.
The first letter of 'laryngitis' is 'l'.
'bing' going around 'l' is 'bling'.
'hum'+'bling'='HUMBLING'

I've seen this clue in The Telegraph.
