eli5 what is this iconic high pitched sound you hear, when a movie or game character activates night vision goggles? Is this a real thing?
In: Technology
The sound is the energizing of high voltage coils. It is reminiscent of the iconic sound of turning on a CRT television. There would have been a time that night vision goggles had tiny CRTs in them like the ones found in old camcorders’ viewfinders and these sort of night vision goggles, worn on the head, may have significantly amplified that sound but in general the sound is used to suggest “screen turning on”.
