@Duane: I don't think such a device would make things any more plesent on your drive though. :-)

Oh I don't know -- if your EMI Gun could deliver a sufficient "pulse" into Gina's car stereo system, it would make things much more pleasent for me LOL

When I saw the headline to this article, I was thinking more in terms of generated EMI. From time to time, I've thought of building an EMI "gun" that would inject electronic noise into the amp circuit, which would turn into audio noise, of passing motorists or neighbors with overly loud music.

I don't think such a device would make things any more plesent on your drive though. :-)

I seem to do a decent job of mentally filtering out most music - until it reaches a certain volume. I do use ear muffs when mowing the lawn or using loud tools of any sort, but they seem to annoy me enough that I don't think I could wear them for an eight hour drive.

@rich.pell: ...especially if you do as Siegfried Linkwitz (of Linkwitz-Riley filter fame) did and add a notch filter circuit to customize them to your ears...

Wowzers -- there's a man who "knows his onions" as it were

"Have you tried these yourself?"

Yes, I own a couple of pairs that I've picked up over the years (I managed to find them for closer to $200).  Like all IEMs they require insertion into the ear canal, which not everyone is comfortable with, and which is not quite as convenient as slipping on a pair of standard headphones, but the sound quality (and noise isolation) can be amazing - especially if you do as Siegfried Linkwitz (of Linkwitz-Riley filter fame) did and add a notch filter circuit to customize them to your ears:

@rich.pell: The Etymotic ER-4 for example provides noise isolation of 35 to 42 dB, which is even better than those bulky earmuffs.

They sound amazing -- and I love the size/weight -- but at $299 I would want to test them out before splashing out the cash...

Have you tried these yourself?

Max - can't wait to hear how they work out for you!

@kfield: These look like a great solution to the "shrieking baby" situation on airplanes where I find my Bose earbuds just don't do the trick. Have you tried them on a flight?

Why not kill two birds with one stone and try out some in-ear monitors (IEMs)?  Not only do they provide great noise isolation, you can listen to your own audio content as well.  The Etymotic ER-4 for example provides noise isolation of 35 to 42 dB, which is even better than those bulky earmuffs.

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
