    Glass Phenomenon
Click For Summary
Recent incidents of spontaneous explosions of glass and lightbulbs on a desk have raised concerns, particularly when these items are undamaged and not exposed to stress or heat. The discussion suggests that ultrasonic vibrations from nearby monitors may cause the glass to resonate and break, especially if the monitor is malfunctioning. Participants recommend conducting experiments to identify the cause, such as testing for unusual acoustic emissions or swapping out the monitor. The possibility of manufacturing defects in the glass is also mentioned, as poorly annealed glass can break unexpectedly. Overall, further investigation is needed to determine the underlying reasons for these occurrences.

lol its an LED.

but funny, i actually got it repaired a month ago.. because of power failure..

ist this 'leaking frequency' a health hazard?

Maybe—if you're a bat. :-p

Quick question: You are all assuming that michojek uses a CRT monitor? They are quite rare today.

Delaminated transformers make high pitched noises. Eventually ultra sound? Might there be one in the speakers or even in a non-CRT monitor? But quite frankly I doubt this could cause glass to break.

Ferrite cores as used in high-frequency switching power supplies exhibit magnetostriction, so can be a generator of high-pitched sound.

How often did this happen?
