People getting electrocuted to death... by their headphones?! This better not be true. Apparently it's happening because they're listening to headphones on their phones while the phone is plugged into the wall?

Snopes says inconclusive... but I don't care about Snopes. My boyfriend told this to me, and I said something like "this is why I don't like the news" but quickly added "I like knowing though - this is how we protect ourselves"

This really seems like fear mongering to me. I don't plan on confronting him about it, I'm just wondering if anyone else has heard of this happening? I imagine it's probably possible to happen if the headphones are crappy and/or there's enough voltage.

I don't know much about headphones except you can use them as a mic, ref: https://djtechtools.com/2015/02/22/how-to-use-headphones-as-a-mic/

Since most (if not all headphones) have rubberized coating on the ear part, I tend to feel as if the engineers have already accounted for this potential deadly issue.

Either way... I think we might want to err on the side of caution on this one and be wary of plugging our ears directly into the wall :/

I'd say highly unlikely. The devices headphones are plugged in to don't generate enough current at all. Even if plugged into the wall, there'd have to be a major malfunction somewhere, and I doubt if a headphone cord could even carry enough current to kill a person.

On the "can be a mic" comment - anything that can generate sound, can in theory also be a microphone. Some nerdy guys were able to turn a computers speaker system into a microphone and listen to converasations in the room. They're not very efficient as a mic, but it is possible.

I'm going to agree with the Duke on this one. Normally no issue.

However, during a lightning storm, a power-line getting struck can route lightning into the house, and it can pop out of any mains outlet, following any cables plugged in, including in that case, jumping across the power charger for the phone, across the phone, across the jacks and into the person. I've actually watched a lightning bolt fry a mains outlet AND a regular hardwired phone jack during a strike right at the pole and transformer at the office. Awful spooky to see that happen..

Moral of the story, don't have any apparatus plugged in during a lightning storm and having the apparatus connected to your body in some way (a charging plugged in phone being held included)..

Agree with Bob. There is a somewhat famous story of a man who had a near death experience and was in the hospital for a very long time, due to being on the phone during a lightning storm and subsequent strike.

His name is Dannion Brinkley and the book is "Saved by the Light".

However, there is some controversy about the story as he tells it.

Electricity behaves in strange fashion, but this seems unlikely. While possible, I would worry about a 1,000 other things first.

no need to worry... unless you listen voodoo music in the headphones, voodoo music can cause terrible lightning storms, it was well documented on an 80's film named Chucky that was based on a real story.

I'm glad y'all think this is ridiculous as I do! My boyfriend came around too, and we agree the "headphones in question" were probably not safe to begin with. Indeed, I've got plenty enough to worry about without needing to be afraid of my headphones.

I use headphones a lot. They're no more dangerous than a telephone is.

I hadn't thought of lightning storms either, excellent points there!

@Petra - I don't think you would get electrocuted from an UN-PLUGGED, not CHARGING phone. If you have a power line to the MAINS, through that line from your phone to the charger to the mains, one is at risk.. Like sleeping with an electric blankey, or heating pad, you are putting something connected to the mains right on your body..

Like taking a shower during a lightning storm, a lightning bolt can indeed go through the grounding, plumbing and thru the pipes in the house, and once again, one could very well be at the end of where the lightning discharges.. During a lightning storm, a lot of charges develop, and even if not immediately struck with a bolt out of the blue, small streamers from cloud and ground can happen, where the charges do indeed build up, into what appears to be like a static electric (rub your feet on the dry rug during winter, and touch a doorknob)... spark.

Being wireless, away from anything metallic, not taking a shower (another conduit path), and one would be relatively safe, unless the lightning bolt struck the structure and blasted it's way through.. That being the case, it won't matter if you are on a phone or not, if one is in the path able to be part of the massive ion storm, that effect will get one shocked.

see post - http://projectavalon.net/forum4/showthread.php?105412-Can-people-really-die-from-getting-electrocuted-through-their-headphones&p=1265077&viewfull=1#post1265077

Lightning in the mains - imagine that to be your body as the juice is conducted through your charger (jumps the gap), through your charger cable, and through your phone into your hand/pocket/head.. Direct connect danger - no connect relatively safe

Danger if plugged into the mains, and charging, connected to the phone:

To summarize ...

Possible, but the risk level is not really any different than the risk of dying from being electrocuted by lightning while indoors..

As Bob says, it's about the low resistance path to your headphones. The low resistance being the copper wires in all our devices. If this path extends back uninterrupted to the plug in the wall there is indeed a chance of electrocution - albeit, a very small, small, small chance (under normal or regular conditions, that is - not electric storms!).

As for the electricity jumping from one ear piece to the other through your head - highly unlikely under any conditions. That is because it is all about the low resistance path. The gap from ear piece to ear piece is very large and the resistance is very high. The most likely path would be along one side of the face and under the skin along the facial lining because it has the most moisture (water being a relatively low resistance medium).

People can die from almost anything, given the exact right circumstances, so I would say, yes you can die being electrocuted by your headphones - but a snowball in hell would have an equal chance of not melting.

Bob
23rd January 2019, 00:56
As Ernie says too, the moment you have wired (low resistance) connections in the circuit and you are part of the circuit, it's gonna go through you.. IF you are WIRELESS, with a good enough air gap, very high resistance, the potential difference between you and the electrical source will have to be high enough for you to feel it, or get harmed.

I actually WAS on a phone, not charging, but a landline phone during a lightning storm.. The lightning blasted the RJ plug right out of the jack, blew the phone off the wall and I could see the surge/burn, and I did get a shock.. Luckily I was on a highly insulated floor with a good rubber mat underneath, and a good rug.

Lightning struck the power lines which had a telephone line running underneath about 1/8 of mile AWAY from my office.. It traveled mainly through the phone line no doubt blowing out everything else on the cable..

Yes depending on your local, if there is lightning storms and you do have feeds from outside to inside your house, and if your power lines do get stuck (on average 10-20 times a year this happens in my part of the world, quite predictably and regularly spring summer. I disconnect all the stuff during lightning - surge protectors are not good for lightning, they explode..

Normally, a surge will burn out the secondary windings in the charger or rupture the resistor in series with the input. But a surge is so fast and can be driven by such high potential that it can still arc across the air gap and spike in your device.

Its actually more about the low resistant path from the actual lightning to a place where it can reach the low resistant path to your headphones. It has to get there first - and this is where the vast majority (like 99.9%) of the lack of risk lies.

Ernie Nemeth
23rd January 2019, 17:19
Yes' the entire path from lightning strike to ear phones must be low resistance. Overhead services are most susceptible. But every service eventually ends up overhead somewhere...
Also, there are other low resistance paths like copper plumbing, steel drains, neutral connections, alluminum siding, and the actual grounding method. Any of those can also host an overload event

Water is a great conductor of electricity and our body is about 90% water if I remember correctly.
We tend to take electricity for granted.

I forgot about arcs too. Even the word "arc" gives me the shudders.

From Wikipedia:
An electric arc, or arc discharge, is an electrical breakdown of a gas that produces an ongoing electrical discharge. The current through a normally nonconductive medium such as air produces a plasma; the plasma may produce visible light.

What is Plasma? From Google:
2. an ionized gas consisting of positive ions and free electrons in proportions resulting in more or less no overall electric charge, typically at low pressures (as in the upper atmosphere and in fluorescent lamps) or at very high temperatures (as in stars and nuclear fusion reactors).

Example of an arc:

In the mines we had to install a service 1 mile underground. We brought 16,000 volts from surface, stepped it down in a secure area to 5400 volts, ran that to the electrical room, then stepped it down again to 600 volts in another secure vault. The method of termination depended on electrical potential. The 16000 volt terminations require a very time consuming method all about arc mitigation. At 5400 volts the terminstions are somewhat less severe. At 600 volts the method of termination becomes almost moot. The arcing at high voltage is so dangerous that the spacing between terminations is over three feet plus contraptions to contain the inevitable arcing. At 600 volts the spacing between terminations is only a few inches..

Even if you were to be electrocuted via headphones you'd be fine (lightning aside). The wire gauge is too thin.

Ernie Nemeth

Ya. Except that the combustion sets up a plasma field of positive copper atoms and its free electrons - another low resistive path even better than the wire. Short-lived but deadly...

An arc, as Petra showed is the plasma - ionized gas molecules.

Well, I am only an electrician so my formal theory is cursory at best. What knowledge I have is from my own initiative.

There is a form of power generation that uses this concept of plasma generattion to strip outer electrons from thier loose orbits around atoms. I believe it is called MHD, magnetohydrodynamics. There are other methods as well.

The creation of electricity is all about manipulating electrons. All atoms in thier neutral state have electrons orbiting the nucleous. Some atoms do not hold on to thier electrons tightly due to various factors, some to do with orbital shells and thier electron capacity.

So, copper has two free electrons in its outer shell that can readily leave the atom under the correct conditions. Other atoms have other combination and charactetistics but the capacity to give up electrons has all to do with the outermost shell of electrons.

If a potential high enough is present, that is if there is enough mmf (magnetomotive force), and an atom is within this field and had free electrons in its outer shell it will give these up to equal the electrical potential.

When these free electrons leave the orbit of an atom, the atom is no longer neutral but positive. We term such atoms, ions.

Since the atoms are 'charged' (no longer neutral) they are subject to the electrical or magnetic field's influence and begin travelling toward the opposite potential - plus charges migrate toward the negative portion of the field, and negative to the positive. The atoms are positively charged and the electrons are negative.

This is what constitutes a plasma, positively charged atoms (ions) and negatively charged electrons. They whirl around the field trying to neutralize it. This plasma, then, acts like a conductor. It is even better than a conductor in that the mmf to make them move is already established and only needs the electrons to continue moving to support the field.

It is a feedback loop. The potential of the lightening strike or other over-current event sets up the field that ionizes the atoms in the vicinity. The ionized gas then moves along the field maintaining the field by that very movement.

Convoluted, perhaps someone else wants a shot at a better description - be my guest.

That was a good illustration, i hear ya. I work on cars so i know basic dc (took a course on it years ago) and how electricity works so to speak (at least in a dc circuit). My point w/ the headphone thing is its a statistical impossibility. One could say anythings possible but thats not a realm I delve into.

Apparently folks that do work on that make good money though. Lightning is fun to watch but haha yeah def deadly. Dunno if its true or not but I read on another forum of (I'm gonna butcher this story) a lightning strike that ran through an underground line and blew a trench open in someones yard.

I need to learn more about ac but i got enough on my plate as it is. Kinda offtopic but just remembered sad story from I think last summer some kid was working for a tree cutting service. He was getting out of the cab of a bucket truck when the bucket extended out, the truck leaned and touched the line. As soon as his foot hit the ground he was out.

Simpler yet.. Soon as even a streamer (a very think not even normally perceivable thread of high voltage) starts to make a conductive path, just like a wire.. Pretty instantly that "streamer" allows the bigger charge with a lot of current (current is like horsepower) to then be conveyed. As Ernie mentioned with the guy with the switch, one is paralyzed, and the rest of the current does the thing it does, seeking the paths of lower resistance, the result being quite dramatic..

I had a strike, and as I pointed out, it does make it into the room because there is a link to the outside.. If one is in an area where lightning can strike, taking a chance to me isn't worth it. Seek shelter and don't use anything that can give lightning a pathway to you.

A little story might illustrate the horrible destructive power of electrical energy.

I ran the job at IBC call center (insurance bureau of canada). There was a punk kid apprentice with a terrible attitude - never serious, always goofing around. I identified his disruptive nature and immediately banned him from the electrical room and gave him low voltage work to do so he wouldn't hurt or kill himself or someone else.

One day he defied me and went in the electrical room to shhoot the **** with one of the senior electricians. While in there he began twirling a piece of uninsulated copper wire around his head. It hit the panel and caused a short circuit.

The short burned through the panel bus bars and created a plasma cascade.

I was outside the room on the phone when sparks and flames and copious amounts of smoke began billowing out of the room.

By the time I managed to turn off the mains four floors down, thete was nothing left in the electrical room. No panels (3), no pipes (big pipes, over twenty feet of them), no switches, no junction boxes - nothing.

Everything melted to a puddle on the floor. Oddly all thst was left was multiple conductors with no insulation left on them. Hundreds of individual bare wires of shiny copper and nothing else.

No one was hurt. We never saw or heard from that punk again...

Volts matter less though than other attributes ... you know this ;)

Bob
26th January 2019, 12:56
Volts though provide the ability to JUMP distances.

Amps provide the ability to convey work.

Work can be melting down switchgear, or being stepped down through transformers to eventually power one's toaster, a "controlled burn".

Unregulated, unguided high voltage can go anywhere it can to complete it's "circuit"..

The damage to meltdown comes from the amps, or the amount of charge density moving within a given space for a measured amount of time.

To get to a person during a lightning event, the volts make the first contact. Then after a path is established, the amps proceed to help induce the "fried" effect.

At 600 volts the spacing between terminations is only a few inches..

If something accidentally happens to the 16k to 5400 step down, then you've got enough voltage in the 5400VAC to jump he gap and sustain...and then the 600 can be overwhelmed, and then you've got some decent high powered welding going on....

and then everything in the entire chain blows, maybe.... maybe before the breakers can open. But that's a lot of maybes.

Considering everything in the mine is slated toward being electrical to cut the pollution, monoxide, oxygen loss, etc..then that's a system designed for a busload of current. Where a dead short with a sustained arc can look a lot like a normal day on the job, to any arc and shorting mitigation aspects of the design.

Could be a messy one, which is why I suspect that it is designed to be a bit aggressive on the trip sensitivity. Seen pole transformers short and practically explode before, but not before they took out an entire electrical room.

The video is probably still in existence, but likely to only be at 'live leak'. Which is not a place to go for the weak of constitution. Most videos there are uncensored non yootoob (forbidden at yootoob) types and can leave mental scars. Humans do rubberneck, though, which is why some will always look...

Strat, you are the master of plasma wielding (welding). Welders use the arc to weld. That bright blue flame is a plasma.

Carmody, the system installed was, if I remember correctly, a 1600amp service at 600volts.

Dedukshun, it takes twenty milliamps across the heart to kill. And the most dangerous voltage is not the high ones - it is the 120 volt circuits. This is because 120 volts puts you into seizure, locking your muscles so you can't release or get away. Higher voltages throw you off the lines.

When I was just a one week old green guy we had to install a 3-phase switch in a mall's service for a new store - live. I questioned whether that was safe but was told it was. Won't go into details but it was the most unsafe work one can imagine and today I would laugh at anyone who would suggest I do something that dangerous. I saved my journeyman's life that day - I grabbed his arm just as he was about to make contact with live parts with an uninsulated pair of channel locks. Unfortunately the fast motion disturbed my other hand with my insulated channel locks and the steel below the insulation touched the bus.

We both woke up on our asses outside the electrical room, me still holding the pliers. They were melted down one side like a waterfall. How we ended up unhurt, or how we got thrown through a closed door, I have no idea...

A few days later we went back and finished the job - on Sunday night and we turned all the power off - duh! I learned to respect electricity that day. That is why I am far above most other electricians. Because of that incident I went way above and beyond the cursory schooling most electricians have, studying in depth all aspects of the electrical field. My knowledge is vastly more comprehensive.

Oh. So how many milliamps can a headphone cable carry, and how many milliamps are needed to kill via said headphones? Is that between brain lobes or just between brain and some ill-defined earthed point?

Top Tip: If you don't really understand anything about electricity; the electronics of SMPS; insulation; X and Y mains capacitors; the different national electrical regulations and their enforcement: voltages and frequencies of mains voltage; human biology and the conditions needed for electric shock; voltage and current relationships WRT human biology, maybe your contributions don't add anything to the OP.
