Daem0hn Posted January 2, 2006 Share Posted January 2, 2006 tried googling, which yielded no results. i have wondered for a long time why when you hold a microphone to your eye, it 'screeches', i have noticed this with childrens toys, cordless phone intercoms, fm micrphones. thanks, --mike Link to comment Share on other sites More sharing options...
david Posted January 2, 2006 Share Posted January 2, 2006 Maybe its a metal plate in your head you didnt know about..... Link to comment Share on other sites More sharing options...
Daem0hn Posted January 2, 2006 Author Share Posted January 2, 2006 ^ hmm, interesting idea..... .....i was thinking more along the lines of your eyes 'pulsating' or oscliating with a frequency close to that of the microphones resonant frequency, but this doesnt explain why it works on lots of different microphones with assumingly different sensor units Link to comment Share on other sites More sharing options...
mattrobs Posted January 2, 2006 Share Posted January 2, 2006 I've never tried it (and am too scared to try it now); does anyone have a sound clip? Link to comment Share on other sites More sharing options...
Daem0hn Posted January 2, 2006 Author Share Posted January 2, 2006 it just squeels high pitched :p nothing scary Link to comment Share on other sites More sharing options...
cold14 Posted January 2, 2006 Share Posted January 2, 2006 i just tried it, nothing happens what have you been smoking :blink: Link to comment Share on other sites More sharing options...
ultimate99 Posted January 2, 2006 Share Posted January 2, 2006 Tried it too. nothing. Link to comment Share on other sites More sharing options...
kernatch Posted January 2, 2006 Share Posted January 2, 2006 you mean feedback? that sometimes happens if you put it near any part of your body.. Link to comment Share on other sites More sharing options...
Toxicfume Veteran Posted January 2, 2006 Veteran Share Posted January 2, 2006 Huh? I don't think anything happens, unless your eyes make some kind of noise or you have speakers hidden behind ur eye. Link to comment Share on other sites More sharing options...
turblety Posted January 2, 2006 Share Posted January 2, 2006 Yeh, it didn't happen to me either :no: Maybe it something to do with the room you're in or sumthin. Mark Link to comment Share on other sites More sharing options...
Daem0hn Posted January 3, 2006 Author Share Posted January 3, 2006 haha, okay, dont i look like the dumb arse, ill have to try and find my bros loud speaker toy and show you that im not an absolute tool :p Link to comment Share on other sites More sharing options...
Rob2687 Posted January 3, 2006 Share Posted January 3, 2006 Yeah...isn't that just feedback? Your eye is just some cells which make up the eye and fluids in the vitreous humor and other crazy names like that. Link to comment Share on other sites More sharing options...
SaLiVa Posted January 3, 2006 Share Posted January 3, 2006 Woah... Somebody is either jobless or has way too much time in his hands... :| LoL High-pitch sound is caused by resonance, so it could be the curvature of your eye socket. Link to comment Share on other sites More sharing options...
quigley0 Posted January 3, 2006 Share Posted January 3, 2006 I would guess that it has to do with the ambient nose in the room, amplified by the natural curve of your eye socket. kinda like standing in the middle of a dome and talking??? Link to comment Share on other sites More sharing options...
_sphinx_ Posted January 3, 2006 Share Posted January 3, 2006 There's a distinct possiblity that a screetch may happen since the frequency of the oscillations of the electromagnetic waves coming out of your head (which are weak and dessipate quickly leaving very ittle energy for the wave to cause the assumed "resonance") can cause resonance in the electronic components and transistors inside the microphone causing a increase in the amplitude of the oscillations. This, in turn, MAY transmit a slight screetch. That, of course, is something that i'm not sure of since I never studied resonance in detail, but this is the only explanation for it. And its really something that;s very hard to explain since I really know vry little about the wave propagation coming out of the brain, and its range. Hope that helps a little Another explanation that comes to mind is this one and its much more plausable: A slight air current may cause a screetch as it passesthrough your head. The variation in the elocity and the period of these currents causes a screetch that may appear out of phase. Seriously m8, can you have a stupider question?!!?!!
