Whats that dreadful noise?? - JAMin, XDA Neo, S200 General

I noticed that when I am calling someone that means having the display really close to my ear and the display is on, I hear a ultra high frequency noise similar to the one that old televisions produce. It is quite disturbing. I would like to ask if anyone has a similar sensation with his prophet. Try to hold the display against your ear while the device is on. Do you hear anything like that? thanks!!!!
Very Interesting fact:
If i overclock the device to 216 and above, the sound vanishes. if i underclock it the sound gets deeper and louder.
What the deal with overclocking?
Did it damage the device?

Nope

thanks for the quick feedback but listen closely, i Believe that this noise exists in every unit.. maybe ??

Nope just tried, don't think it matters but I do have a Qtek S200 with the latest Dopod WWE ROM loaded.

thanks for the try, I am very suspicious that the overclocking of the device to 216 MHZ caused this damage. If i clock it down to 180 it starts making this noise. WHAT HAVE I DONE!!!!

It's highly unlikely that overclocking has caused this problem. You have surreal hearing abilities maybe?

yes, there is always a high pitched noise whenever the display is on from the very begining... device is a dopod pro 818 HK version. A rom change (x-vendor) did not make a difference. still there today
regards, Alex :?

I can hear it too... NOT happy with this! :evil:

Ehi guys,
You're dealing with devices working at high clock frequencies ! That noise is quite normal... I can hear it even getting my wireless mouse close to my ear... Nonetheless I can understand it could be annoying if occurring on a phone device...
My 2 cents.

I think that it's the screen that makes the noise. I have a screen off key assigned to the memo key and the noise stops when the screen turns off... I use it all the time if I am making a long call...

I have this sound on the backside of my display, when i open my Wizard! Seems that it is the display or digitizer or whatever

Overclocking mine to 228 gets rid of the high pitched sound :?:

Hi,
it seems that the noise is produced by a defective electric part of the display. It is not the effect of overclocking. On the contrary overclocking is the solution. If you overlock the unit (or underclock it, if you're in doubt) the broken part will not get in resonance and thus will not produce any noise.
I had the same problem with my Palm Tungsten and overclocking was the solution. On the Tungsten it was definitely a problem of cheap displays.
Keep quiet, just overclock.

It's not faulty, it's what this type of screen does. Google it and you'll see. If you can only hear it when the phone is close then it is fine, if not, then maybe try to return the unit.
The reason why some people cannot hear it might be down to the fact that as you get older the highest frequency you can hear drops off. Try it with some older people... it's a bit odd that you end up hearing something that others cannot.
If it's annoying, over clock it or use the screen off setup like I mentioned.

No, making noise is definitely not a normal behaviour of lc-displays. My Neo does not (yet?) have that problem. That special part is faulty and there are chances that the sound will get louder and louder. That is how my palm tungsten behaved. It seems that history is repeating.

You are right, hearing gets weaker while people get older. But this has nothing to do with that special problem. My hearing is excellent and I could clearly hear the noise produced by the display of my tungsten, that started after three months. No noise yet with my Neo.

Anyway, Google the problem and you'll see that lots and lots of people are asking why their screen whistles... Mine whistles, but only slightly. I think it is down to the screen and not a problem at all.
It's not just Windows phones...

And also this thread suggests it's the touch screen side of things.

You missed my point with regards to the drop off of hearing. I was pointing out that people lose their ability to hear such high pitched sounds as they get older. This could explain why one person on the forum says he can hear something and the next person cannot.
What is this 'special' thing you keep talking about.
M

Here is the deal. I called the o2 XDA support hotline and I was told that this sound is produced by a faulty part in the display (some kind of transistor) and that if the sounds is hearable even if the device is not held close to the ear I should return it under warranty. In my case, i can hear the noise when I work at night and everything is quiet which is VERY annoying. I decided to return it and get an exchange unit.
Indeed, if I overclocked the device to 216 the noise would vanish eventually but I am not willing to have a constantly overclocked device or any kind of obligatory change. I can promise you that this noise is not standard for the neo because I testet it with more than 3 devices of friends.
I really hope that overclocking did not cause this harm else I will not overclock it anymore even though i really want it.

I guess that all devices* cannot be faulty though....?
*all brands/phone etc that have a whine

There may be many people that have this sound, but you can not draw a conclusion about the percentage. If you search for a problem, the results suggest that the problem is bigger than it is in fact. That is because people without that problem usually won't tell others in a forum.

Once again: you are right, but it's irrelevant. As I already mentionend, my hearing is excellent and I could hear the sound with my palm and some (not all) other PocketPCs. But as for my XDA Neo there is no sound.

According to my research it is likely to be a coil that is not well mounted. Have a look at this german posting concerning the palm:

Where in that quote did I draw a percentage about how many people have that sound? I merely pointed out that there are many people who are questioning why their screen makes a noise.
You mention about people report problems far more than if there is none, I agree. But you need to take into account that people are asking the question across phone and phone platforms and about laptops. Therefore it is okay to assume that there some reason why these screen make a whine.
Granted your whine (your phone that is) may be greater than the one that I can hear when my ear is very close. The whine I hear is very high pitched and stops when I turn the screen off. It's not got louder, it's not changed due to over clocking and returning the speed to its original speed. Therefore are we infact hearing two different things? Who knows, just stop miss-quoting me and making out that you are correct. I am merely putting forward more evidence as to what the whine is and that it's not limited to these phones.
Still missing the point about the hearing bit and it is relevant as I was talking about everyone, not just you with super hearing (notice in my previous quote I said 'people' not you), marka2k said that they could not hear anything... so it may or may not be faluty or they might not be able to hear a high pitched sound anymore (sorry marka2k if you can )
As for the research (dont you mean you googled?), they would be in German... cannot be arsed to translate the page as I feel I must tell you again. I was only stating a fact that people are questioning why there screen on their product (phones, laptops, tv) make a whining noise!
If your phone is faulty, fix it or return it to the manufacturer or sell it, or throw it in the bin and buy another phone that does not whine.

TMO Wing Buzzing?

I have noticed that whenever the screen is turned on with my TMO Wing, there is a rather anoying bussing sound. Have any Wing users experienced this? Any Herald users notice?
Actually now that you mentioned this I put my ear really really close to the screen while it was on in a quite room and I could hear a faint high pitched buzzing. But for me I have never even noticed it before it is soo faint it's almost never heard.
no buzz for me - xda terra - htc 4350 100
Try to change the Clock speed of the CPU e.g. with BatteryStatus, this will change the "buzz-frequency", I also thought it was the screen, but it was the CPU -lol

I have been playing around with the clock speed. It is certainly the processor making the noise, not the screen. The noise has gotten louder while I have been using, even while keeping the processor at 201 mhz. I might take it into tmobile this weekend and see that they have to say. Also, would like to compare with a unit they have on hand to see if mine is in fact any louder than the others.

My wizard only lost the noisy beeping when it was running higher than 246Mhz. Running on 195Mhz the normal speed I had a loud beep all time. So i ahd to overclock.

Don't expect them to do anything though, it is very normal..
Tmo Buzz
I bought my Wing used, and as soon as I turned it on I heard the buzz. Lucky for me though, I used to be a supervisor at mobile and was able to get it exchanged. The replacement didn't start buzzing until about a week after I got it. Now that I think about it, I agree that it's the processor. I probably started to notice it after I got other apps installed.
So what I recommend is this... do an exchange for now just to get tmobile documenting the processor issue. Once tmobile gets the next Wing version in, start doing exchanges on the screen buzz. After so many exchanges there's a chance they'll offer you a multiple exchange and will hopefully offer u the updated version. Lots of wishing in this because we'll have no idea if they're offering the multiple exchange.
I'm sure that none of you spent the money on the phone to have that annoying buzz mind fuc'n you all day. It drives me completely crazy. So I guess we'll just have to keep watching the forums until september and see if the exchange is an option.
***Oh ya, they'll do an exchange with for this issue because it's not the norm at this point. The problem is that most the techs are convinced it's due to water damage... so they'll probably give you crap and run you around a bit before exchanging it.
Just an update...
Using battery status, the sound did change and was actually better the faster the processor was moving. As I did not want to keep it at 288 mhz (for battery life and device longevity) to keep it as a dull noise, I returned it to t-mobile store.
They certainly felt this was not a common occurrence and have only had one other issue like this at that local. Swapped it out with no issues.
Phone is now completely silent with no buzz whatsoever.
Their tech guy at the store wanted me to do a hard reset which I did not do. He felt that this might fix it. Who knows...
Well I am soon to by onto my third wing now. After about a week of having the second wing, buzzing started again. I was on the phone with TMO and they are sending me a new one. They still have no record of this being an issue in their system and did give me the runaround about returning it. Also, they did charge me $10 to send a replacement the first time. This time I made sure they sent it for free.
Hopefully 3rd times a charm...

No, it's not. Mine doesn't buzz
Ya, my Wing just started to make this noise. I used to get it all the time with my Razr. I thought the noise was coming from the Lcd, cuz when I'm making a call, and I turn off the screen, the noise actually stops.
I run my Wing at 234 and scale up to 273 with a boost up to 286. I never heard the BUZZ, but then again, I have my own problems with SD card corruption.
Id gladly take the buzz in exchange for a non-SDCard-corrupting device.
My wing buzzed since the 1st day I got it.
2 weeks later, it comes to the point of TOO LOUD.
Just called T-mobile to get exchange. And have to pay $10 for the shipping! This sucks
I noticed my previous wing buzzed.... but my new one doesnt and I'm running BatteryStatus @ 273
This makes me unhappy! I just ditched my Palm because the screen whine / buzz was so bad. I will keep my fingers crossed that my Wing will stay buzzless. There are some actual hardware hacks to stop screen buzz but it require you to open your phone and manipulate the LCD.
I think the buzzing occurs after your overclock your device, but it should also disappear if you overclock....hmmmmmm
Mine buzzes when the CPU drops below 201MHz. I was getting a really annoying buzzing sound whenever I was using the phone because it would clock below 201MHz, so I just decided to use application based overclocking and keep it at the stock 201MHz. No more buzzing and it seems to be helping the battery life, as well.
Just received my 5th replacement Wing
Well Im not really to sure where to start out. But im definitely glad to have found other T-mobile Wing users who are having the same horrible issue. I received my 5th replacement phone about 5 days ago. Every phone I have sent back was for the high pitched noise coming from the screen/speaker. The new/current phone i got was perfectly clear and had no noise whatsoever for the first 2days. Then, all of a sudden it started and has progressively gotten worse. I called T-mobile yesterday and told them about the problem and actually gave them this URL to document that other customers are having the same issue. Everytime I call them they say, "wow, I have never heard that before." And they always have a test Wing there that they power on and they always say that they don't hear any screen noise. Im starting to wonder if its something else that maybe I doing or downloading that is causing the noise. Do any you have 3rd party apps installed like SPB Mobile Shell or Pocket Plus? Or do you any of you use a car charger or charger that was maybe not specifically deisgned for the Wing? because I have and I am starting to maybe think it has something to do with the noise. It probably has nothing to do with it but Im just curious. I am going to call them again tomorrow and try to get my 6th replacement. And I will continue to call until they fix this issue. I renewed a 2 year contract and with them and also payed something like $350 for the Tmobile Wing. Since that time, I have had to pay $20 for shipping and handling of the replacement phones, and up until my current replacement, they have all been refurbished phones, I think. You can usually tell by how solid the phone feels and it will usually feel a little looser or like someone has used it before if its refurbished. Sorry for the long post, but just trying to get a lot of questions and info out of the way. Please post back with answers to my questions and or any other updates you may be having with T-mobile and this screen noise issue. I at first thought it was coming from the speaker up until now, it is definitely coming from the screen and is louder than any of my previous phones. Its completely ridiculous to have paid this much money for something that does not work/sound/perform properly like all other Pocket PC phones. My friend has the HTC Sprint Mogul and he has no issue with screen noise. He has had the phone for over a month now and the phone sounds amazing to the ear compared to my wing. Anyways keep up the posting in this forum so we have proof of our issue to Tmobile...

Annoying whining noise from screen - where do I stand?

Hi folks,
I thought I'd get some opinions from folks here regarding the screen whine issue that some LCD screens get.
I recently bought a replacement Tytn off ebay after breaking my screen on mine. When it arrived it looked fine. I put it on charge and started cleaning it. That night I find out it's got a high pitched whine making it almost unusable.
I've sent it back to the seller and asked for a refund but he says he's contacted HTC to find out if it's a recognised fault or not. If it's not something that HTC acknowledge then he's going to make me make arrangements to pick it up from him.
Does anyone know if this is a recognised fault with the phone?
AFAIK, I have got some experience with some other handheld, it appear the pitch noise come from LCD inverter. seen some picth noise in early production of O2 Atom, old handera handheld. even nokia e61 generates pitch noise if you listen it closely. what I can not confirm is where the LCD inverter located, in mainboard or in LCD modul it self. So I can ot tell you which one is broken.
Well, it's just my opinion.
Thanks for the input tianz.
I've found loads of info on Google about it. It appears to be quite common with some of the older mobile phones.
Is it reasonable to expect me to have to accept a phone which has an audible whining noise to it?
Well... actually it's up to you, If you find the whining noise is too loud for your ear maybe you should return it while you can. As my experience when I had Handera with whining noise, I had return it. but when the replacement came back, the whining noise get worse and the company said that there's no problem at all with my Handera.
Later on I found out what cause the whining noise, and actually very simple to fix it, just find the inverter ?? (sorry I don't know what they call it in english, It's ferit core and copper wire wrapped around it) and put some wax from the candle or you can use glue.
And again, I don't know where exactly the inverter located in Hermes device, or maybe they use different model of inverter in Hermes.
So, It's up to you. I hope my answer will satisfied you. Thank you
Unfortunately I bought the phone off ebay and the guy isn't keen to refund me - although he currently has both phone and my money.
He says it's not that loud/irritating so I'm not sure what to do.
I've just dealt with it. The whine is only there when the LCD screen is on. My 8525 phone is exactly 1 year old. It can be irritating though, so I use the earbuds whenever I can.

Unfortunately for me the guy that's selling me the phone doesn't appear to agree that it's annoying:
=========================================================
"I have tried the phone and whilst it is just possible to hear a noise if I put my ear to the screen (why ayone would need to do that I have no idea) there is no audible noise when the phone is held to the ear as used in a normal phone call"
=========================================================
I can hear it loud and clear even at arms length - the phone doesn't even need to be near my head!

if you do have the phone in your hand, please confirm the pitch noise come from the front speaker or LCD it self. I'll try to help you finding the inverter located. I'll look around if I had a chance to open my 8525 again. Thank you
i am on my second tytn. I bought both used and in PRISTINE condition on Craigslist. The first one I bought had it, and so I asked for my refund from the seller. The second one (that I have now) just started the whining noise yesterday. I've had it since January 2008. It SUCKS!!!

PS: the noise is heard when I put my ear to the front speaker up close. It's weird. I heard it as soon as I move my ear to it. However, after about 5 seconds I don't hear it anymore. Then as soon as I move my ear away, I hear it again... It's like my ears become desensitized to it? lol

[/QUOTE]
It is quite possible. It's like being in a room with an analog clock. You may have sat in that room 100 times, with the same noise around you, but for some reason this time you can hear the tick tick tick of the hand movement. Then just as quickly as you noticed it you can suddenly not hear it no matter how hard you try.
It can be a state of mind that results in your heightened sense of hearing or it can be as simple as your tympanic membrane being a little tighter.
Like the above poster said, I hear mine sometimes too, and other times I dont hear it at all.
To the OP, if the seller has your phone and your money, then either keep asking for your money back and if that doesnt work, email ebay or give him bad marks stating what he has done. If that doesnt work, you can threaten to take him to small claims court ( Judge Judy ). What is loud and irritating to you maybe not to him. Get you rmoney back. Hope this helps..
I think the reason the sound goes in and out is due to the fact that the screen istelf goes to sleep after a few seconds, or what ever you have set in the system...
My screen starting making this noise a few weeks ago. I love the functionality of this phone, but I am pretty much done with it. I can't stand all the tweeks that come with it.
I jumping to the iPhone as soon as they make the slinbox player for it... and they roll out the 3g functionality.
Don't mean to rant, but I am just frustrated.
I think the phone was dropped of damaged and that is why it gives off a high pitch sound.. Mine dropped onto a hard concrete floor. It looks and works perfectly fine but immediately after it emits a high pitched sound when ever the screen is on.
This is not normal for the TyTn which means it was damaged in some way prior to you getting it. Demand a refund.
Hi guys - the person I bought the phone from is still waiting for HTC to get back to him so he still has both the money and the phone.
Even if HTC say it's not a recognised fault, it's still unusable to me because it's really loud to me.
I'm not sure there's much I can do as I'm not exactly in a strong position to make demands.
Personally I think it would be unreasonable for him not to refund me but then he might not be a reasonable person.

The sound is definitely from the LCD - the speaker is fine once the screen is switched off (i.e. you can turn the screen off while on the phone and it's still fine).
I've had 3 8525's, one of them had this problem from day one. There have been a few threads about it as well.
I have just learned to turn my screen off during a call. It's real easy and quick, besides, you aren't looking at the phone when you are talking on it, and if you are, you probably can't hear the whine.
However, if you don't want to deal with the whine, then don't. Hopefully you paid through paypal and can just file a claim if the guy doesn't want to be fair. It is a defect and they should back you up.
If not, look to ebay and see if there is anything further you can do with them.
Call HTC yourself. Don't wait for him.
good luck
yes mine also does it i have just learnt to put up with it, but yes like drakkahn said you should ring HTC yourself and see what they have to say

some information:
1. I have closed the camera app normally. I didn't suddenly took out the battery while the app is running.
2. The noise is actually pretty loud even with the battery cover on.
3. I used normal strength to do the experiment in the video. I didn't intentionally increase the strength to make it a problem.. Just like you casually put the phone on the table ...
Thanks!
yes shaking the **** out of it will probaby jack it up! just kidding mine don't do it
so bad luck i am ... gonna shake HTC in order to get my money back from their mouth..
The noise itself is normal, afaik everyone's phone make that sound.. However, and this could simply be the way it was recorded, your's sounds louder than both N1's have held (the two I had were identical). Again, this could simply be the way it was recorded.

Thanks bofslime, I would say the actual noise is louder that the one in that video. My original phone only makes noise while taking pictures. If you shake it, it won't do so. But this replacement does. That's why I become so nervous and want to check how's everyone's doing.
Thanks for your reply.
The consensus is that it's the auto focus mechanism on the camera rattling. Mine does it too and I suspect most (every?) other nexus one does too.
It's kinda annoying, but nothing 'wrong' as such.

I hadn't read the query just clicked on the video. Figured it was some nexus porn. *excuse comment this is of no value*
My camera rattles a little bit too when I shake it and/or give it a light tap on the battery cover near the camera. Hoping it's normal....

Screen whine ?

I recently purchased an a501 and I noticed for the first time today that it has a faint high pitched whine coming from the back of the unit, most noticeably from the speaker cutouts. It gets louder when plugged into the charger, but is still extremely faint. The noise is not present when using headphones, and adjusting the brightness or turning off the auto brightness makes no difference. I originally thought maybe the speakers were picking up something, maybe from a bad ground, but the noise is extremely consistent. it never changes pitch and only gets slightly louder when plugged in.
http://www.youtube.com/watch?v=qbBNIfeDp_4&feature=player_embedded
I have tried a factory reset hoping it was a bad driver install or something , but it is still there.
Don't notice it on my 501. Could be an issue with a somewhat faulty speaker connection internally.
Could be RF interference also. Have you taken it to a different location other than your home?
This is a judgment call on whether to keep it or return it for replacement. So if you can live with it, keep it. If it disturbs you, then replace it.

Internal RF noise or audio gain set to high in software. What rom and kernel are you running. I would exchange.
I noticed the whine when charging, its very strange that when i scroll a web page the whine gets louder and quiets when i stop.
Never noticed the whine while not charging, in am not sure it comes from the speakers, if i place my ear on the device i can hear it basically everywhere.
I have a stock a500 on 3.2
My first post on XDA nice to be here
Change it. It shouldn't be doing that. Your new post confirms this.
Probably, something internally, is not shielded correctly. As I stated somewhat earlier as with improper connections and RF interference. But it seems the RF, is coming from your tab. I'll bet, somebody forgot to shield something.
Probably, your tab will not be effected mechanically. Probably last for several years.
But that noise, if it bothers you, is abnormal.
I have a stock a501 with 3.2, from Orange Romania.
may be a software error?

I really, really doubt it's a software error. High-pitched interference that goes away when headphones are plugged in, ie. when the speaker assembly is turned off? That actually reminds me of these age-old audio cards built into PC motherboards 6-10 years ago, they almost always produced this high-pitched interference sound that went immediately away if you switched to a proper discrete audio card, without changing any other component or software package in the system.
Nope, I do have to agree with posters above: there's likely shielding missing somewhere or perhaps it's gotten loose and that's why you hear that interference. Such an issue cannot be fixed with software, but it also won't damage anything, ie. it's not dangerous and it won't cause any other damage to your tablet. Backup everything and take it to warranty repair, explain the issue in clear terms and ask for a replacement.
What is strange, it reaches 80% load noise disappears.
The noise does not disappear if i plug in the earphones, perhaps if i stuck them in my ears and play something i wont hear the noise, but its stil there.
My girlfriend has already started complaining about the noise when i charge at night by the bed
Can anybody absolutly confirm they dont have the noise on their a500/501
On my tablet A501 there is this noise. In Romania it is hard to find service stations, to be performant and serious.
There are two service stations approved by the importer.

Well, I can. I have absolutely NO noise whatsoever, when charging or when not charging.
Are you charging it when you hear the noise. The charger's transformer whines when in use. This is common on almost every transformer. The a500 charger is lowd! I can hear it across the room.

I have no noise at all out of mine.. If it did it would have been exchanged .
I think this is caused by what electronic people call dirty dc voltage..can be anything from a grounding issue. bad capacitor on the electronics to a trace on the silicon boards to close together. and on and on..
I WOULD SAY send it back or take it in and exchange it .
Noise bothers me very badly i even trained my spouse you YELL AT ME Silently when she is upset about something .

Frankly, aside from this problem with buzzing, tablet works very well. I think they send back to Orange and to come worse than now.
I sent a message to the service dealing with Acer, but they said that if the tablet is functioning normally, there is no problem.

Well, if it functions normally, and you don't wish to argue the point, what can you do? Like you said, get something worse in return? It happens.
If you can live with it, well, then do so. I suppose one could pop off the back cover, and check for shielding, as I believe that is the issue. Probably some idiot forgot to put a little shielding around a certain part during assembly, and you get the RF noise.
Unfortunately, people in the States do not quite understand how things are in some parts of Europe. You just can't return it, when it functions correctly. Not sure about Orange's policy.
Well, it works fine, but, if you have any questions, please let us know. We can help you on the other stuff.
Happy New Year to you!!
I have no strange noises coming out of my Iconia and my charger doesn't make a noise either.
As far as I'm concerned an Iconia making strange noises is NOT functioning normally. It could be a symptom of a larger problem and your tablet might suddenly die, you can never be too sure if it will or not.

My A500, had it for two weeks, whines when it charges. The sound doesn't last long. I'm not sure where it's coming from, but I think the tablet, not the power transformer but will check tonight.
The A500 has a one year warranty (US), so based on what I've read here I won't be sending it in for rma unless it breaks. I love really like the A500 but a year from now will be ready for something new.

Noise occurs when using the tablet( when in charging) ? or, when it is in stand by( when in charging)?

[Q] For those with their Nexus 4, is the earpiece making a screeching noise?

If I place my Nexus 4 against my ear, I can hear high pitched screeching and some popping coming from the earpiece, even when a call is not taking place. At first I thought it was a heat issue, maybe some capacitors or something getting a bit hot and whistling, so I turned the phone off and the noises stopped instantly.
This is pretty annoying and surely shouldn't be happening
Yes, mine too

I'm glad you posted that, mine does it too - and I thought I had a faulty phone.
According to support I'm the first to report such a problem, have you called support about it? - 0800 328 6081.
The more of us that call, the better the chance it's sorted (if it's possible).
I can't live with that noise, it's too loud for me as I have sensitive hearing on interference like that.
So it looks like I'm sending mine back for a refund and go buy a S3
It does sound like poor build quality in suppressing electrical interference to the ear speaker, as you say capacitors or even a processor is leaking noise to that speaker in the same way cell/mobile radio causes to external speakers when brought close to them.
WOW so many problems already with this thing!!! I don't know about this phone right now

I returned it to the store for a refund - they refused to swap it for another as they couldn't hear it . I've ordered another which I should get tomorrow, and if that has the same issue I'm not sure what to do - it doesn't really sound like something that can be fixed through software, does it?
I asked on another forum and one person replied saying that there's was ok, but maybe they're ears just aren't as sensitive as ours.
I remember as a kid, I could hear CRT TVs from a long way off (no sound was coming through the speakers) and nobody else could.

I think you're right, I too always heard a CRT working (I still can when I see one working!)
Maybe we're hearing interference the average user is not going to hear.
If anyone else is reading this and owns a Nexus 4, try calling your voicemail (which I assume would be free for you) - during the call wait for a few seconds and listen carefully, it's more obvious when you're not talking and in a call.
The noise is almost like having a small fly trapped between the phone and your ear at times, it also reminds me of the noise a hard drive makes at times and most of us know what that sounds like.

I got it even when I wasn't on a call - a few seconds after powering up the phone and it was there
You guys are nerds
No, I can feel your pain! Hopefully you guys can sort this out and this is in general not a common problem with the N4.
i don't have this issue
It seems to be an issue with the electromagnetic shielding. I get this problem when I am next to my sound system and amplifier. Those things arent shielded. Now in school where theres basically nothing else here my earpiece is completely clean. Not even a hiss.
does it also emit a sound when it is swithced on, but the screen is off? i remember i had sth. like this (high-pitched sound) on my first google nexus s, but it was clearly coming from the screen rather than the earpiece.
Received a replacement today - it's A LOT better. There's still a very feint buzz, but it's barely noticeable.

Yes, even did it without a simcard inside. Definitely coming from the earpiece, if I moved my ear down the phone it was quieter/silent.
What about in airplane mode?

Didn't test the previous one in airplane mode, but just tried this one and it's the same.
Definitely getting the same issue with my N4; screen on or off. Can't imagine this being fixed by firmware, sounds like a bad hardware design.
I'm also once of these people who gets irritated by the sound of DVD Players/VCR/TV etc. But two other people I have shown seem to think its an issue too.
It's good to read a replacement was better, that's made my day.
The problem is certainly a electromagnetic shielding issue with the earpiece, I can stand in a middle of a field and it has that sound you often get from PC or Hi-Fi speakers when you stand close to them.
But with the earpiece you can't move it of course - so clearly a design flaw, and hopefully only on a batch?
That said, it does seem to be an intermittent fault, I've also noticed it doesn't happen within the first 10-30 seconds of a call. I wonder if the phone stops all background processes during the start of a call, but then later kicks in which causes those noises.

I can hear the high pitched noise from a CRT from, like, 100'. Can a lot of other people really not hear them? Also, deer/dog/insect deterrents that people use in their homes and yard give me an instant headache from the sound. Great. This does not bode well. Oh well, I'll cross that bridge if/when I get to it.
Same here

Exactly that, those who can't hear those audible repellents for pets, or not hear the Apps available which also emit very annoying high pitch sounds - then would not be bothered by the noise we mention here.
I'm certain if I took my N4 into a shop, the typical response from staff would be "we can't hear it"
I have this issue with my phone as well. Screen on or off. Charging or not. Noise is still present.
