Kid influenced by sound (5)
I believe the answer is:
suede
'kid' is the definition.
(both are types of leather)
I cannot understand how the remainder of the clue works.
(Other definitions for suede that I've seen before include "Soft leather with one side napped" , "Leather with a soft napped surface" , "Undressed kidskin" , "leather material" , "Soft goatskin" .)
