Noise from building (3)
I believe the answer is:
din
'noise' is the definition.
(din can mean a loud noise or disturbance)
'from building' is the wordplay.
'from' indicates a hidden word.
'DIN' is hidden in the letters of 'building'.
(Other definitions for din that I've seen before include "Hubbub" , "Clamour" , "Distracting noise" , "Loud annoying noise" , "commotion" .)
