Translation(s) of '지지직' meaning a sound?

Question

I saw '지지직' in a movie subtitle, and inferred its meaning as something like a 'crackle'.

However, another example I found online was

지지직거리나요? Do you hear that?

And other examples suggest it could mean 'noise' in general, whilst a youtube hit of a sound effect I found seemed to be more a 'hiss' than a crackle.

What is the range of translations of '지지직'?

Answer 1

지지직거리다 means 액체가 졸아붙으면서 끓는 소리가 자꾸 나다. link in official Korean. but Koreans use it when electronic devices's sound or screen goes wrong.

Answer 2

"지지직" means white noise like this (It's too noisy, so you should turn down the volume).

You can use "지지직" for this kind of noise.
