Very much like the sound a door makes (5)
I believe the answer is:
adore
'very much like' is the definition.
(I've seen this before)
'a door makes' is the wordplay.
'door makes' becomes 'dore' (I can't justify this - if you can you should give a lot more credence to this answer).
'a'+'dore'='ADORE'
'the sound' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for adore that I've seen before include "Treasure" , "Honour" , "Love, worship" , "Worship, venerate" , "Worship, idolise" .)
