Magnetic disturbance and the brain
Jul 20, 2001 at 8:23 PM Post #3 of 9
actually, that article has nothing to do with magnetic interference with the brain.

Its about magnetic headphones interfering with MRI (Magnetic Resonance Imaging) scanners.

I don't the article would be very interesting to anyone not doing research on audiatory perception.

True, although it's interesting to note that the headphones used were modified Baby Orpheii (HEV60/70), combined with something called Bilsom ear defenders. Also, it's rather ingenious how they managed to make everything as non-electromagnetic as possible (running fiber for the audio signal [necessary since MRI machines use RF in high power], planning to use carbon fiber cabling...). The article isn't *that* dense, mbriant, although if you want a quick synopsis, then the article talks about headphones that are:
a) comfortable on the test subject
b) are nonmagnetic, and don't interfere with the MRI
c) can handle loud volumes (100+db)

and how everything was set up to do experiments to find out how the brain reacts to loud sounds.

Thanks Eric343....I guess I'm the "dense" one.

LOL, don't worry. My father is a radiologist so I've been exposed to this stuff all my life. Also, I seem to have a knack for reading this type of stuff

I guess, if you are really worried about magnetic disturbance you should rather avoid electric shavers than headphones...
