White noise can be fixed (6)
I believe the answer is:
static
This clue could be a double definition.
'white noise' is the first definition.
'static' can be an answer for 'noise' (static is a kind of noise). I am not certain of the 'white' bit.
'be fixed' is the second definition.
(I've seen this in another clue)
'can' acts as a link.
Can you help me to learn more?
(Other definitions for static that I've seen before include "Noise caused by electrical interferance" , "Not moving or changing" , "showing no signs of going anywhere" , "Motionless like some kind of electricity" , "Unmoving, still" .)
