Soundbite dismisses Ben in the drawing room (6)
I believe the answer is:
studio
'drawing room' is the definition.
(room in which an artist might draw)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for studio that I've seen before include "Workplace for artist, photographer etc" , "Place for the practice of an art" , "Unpleasant vapour" , "Film-making company" , "Here one may record" .)
