Anyone ever hear a loud high pitch noise

For the past week, I have heard a high pitched noise from my imac. It usually occurs when viewing videos and will go away once computer is shut off. It does ring when booting back up then goes away until a video or song is being played on the computer. Apple Support told me it wasn't something they could fix because the noise was heard during reboot. Any ideas? Thanks

Please describe "loud"... I hear once in a while a clicking noise that I know is coming from the hard drive while there is a lot of activity. It is noticeable, but I wouldn't say it's loud. My MacBook Pro does the same thing and at some point I was concerned but I found out that these noises are "normal" during a lot of disk activity.
I would still call or bring it to an Apple service store like the above suggestion, just in case! If you don't live near a store, maybe they will be willing to hear the noise over the phone? Just a thought.
Manolo.

Sometimes while talking on my iphone 5 i can hear a loud high pitched tone

sometimes while talking on my iphone 5 i can hear a loud high pitched tone

Hello ssnow71,
Intermittent issues can be some of the toughest to troubleshoot but I have a few recommendations for you.
First if you havent already, then I would restart the iPhone.
iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting
http://support.apple.com/kb/ht1430
Restarting your device
Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
Press and hold the Sleep/Wake button until the Apple logo appears.
If the issue is not resolved, then I might suggest resetting the iPhone next.
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
And if all that does not resolve the issue, you may need to backup and restore the iPhone otutright:

Sounds like you need to take it to a technician for evaluation and repair.

WRT330N High Pitched Noise

Hey everyone,
I just today recieved my WRT330N Gaming Router from Newegg and ever since I hooked it up I am hearing a VERY high pitched noise constantly coming from the router. I've even tested putting my ear up to it and unplugging it to make sure it was the router that was causing the problem. Everything else on the router works great but this noise is really starting to annoy me! Before I purchased this router I had a WRT54GS and never had a problem with it.
I've tried searching to see if anyone else has experienced this but have come up empty handed. Should I exchange this one for a new one, or get my money back? Has anyone ever heard of this happening?
Thank you.

@ Klatch
I tried all of your suggestions previously but they didn't work. I ended up sending it back to Newegg today for replacement. I'm REALLY hoping it was just a problem with that specific unit because if it's not I'll have to return it for my money back. The noise was just so bad...

N95 - High pitch noise (hiss) and GPS struggling t...

Hi Guys.
Since I bought my N95 I can hear a hiss even when I'm not on call (all the time) and I bought Nokia Maps Navigation and it just worked once (a fews minutes after I bought this service). Now it's not working anymore (I've paid for 1 month service and it worked for a few minutes)...
Are those common issues? I read someone complaining about a high pitch noise (and saying that he had to change his phone more than once so it finally was replaced for a non-faulty one).
Any help appreciated...
Regards,
Daniel

I do not know, people just get unlucky, I think. As I said, mine has had no problems whatsoever since I bought it in April. None at all. No noise (yes, no noise at all) no flimsy slider, no problems with GPS, nothing. My experience is that most people who have troubles had a phone 'made in Nokia' (meaning some third world country with slave child labour)whilst every decent working phone is made in Finland, where it should be!
Check where yours is made in.
I must dissagree with you .. Mine is Made in Finland .. it came in grey box .. not the white one .... Mine has High pitch noise .... And about the High Pitch Noise you should know that not all ppl can hear it .. I have some friends that do not hear it at all .. others can hear it only with one of the ears .. others .. like me can hear it loud and clear ....
Perheps I should damage my hearing so I will not be able to hear this annoying high pitch noise
Well, my hearing is fine! I honestly do not have any high pitch noise or anything. I gave the phone to 7 of my friends and they could not hear anything either. I do not know, perhaps you got unlucky. But you are one of the very few with a phone made in Finland that I am aware of having troubles...

Apple EarPods high pitched noise.

Whenever I use my Apple EarPods for phone calls, people on the other line are complaining that they hear a constant high pitched noise. What could be causing this? (Note: I just bought this pair 2 days ago.) Please help.

so bring them back.

To Apple Engineer. I hear a high pitch noise when surf flash-intesive sites

Hi. All.
I have a Aluminum PowerBook G4 1.25Ghz SD. I agree this is a great machine. It has a somewhat out-dated G4 Chip in it, I can do almost everything I need.
I've been using this powerbook for 2 years. Since sometime ago, I've heard very annoying "Hige Pitch Noise" from PowerBook. From further investigatin I found that this was a problem related to G4 CPU Processor throttling- so called "NAP" status. In Flash-intensive Web site, I clearly hear the noise.
According to solution suggested by talented apple user, I did followings.
1. Download or Install Developer Tools.
2. Download and Install CHUD tools from ftp://ftp.apple.com/developer/ToolC...ormancetools/
3. After installing chud tools, there maybe Processor pane in preference app.
4. In that processor pane, you should uncheck "Allow Nap" to reduce the notorius High Pitch Noise.(warning: it may increase the power consumption and temperature of CPU a bit, and of course you would see more frequent activities of CPU fan than before)
5. feel the silence.
To Apple.
I think this solution should be suggested from you not users.
Why we investigate, search the web for thosand of bucks PowerBook. Please fix this annoying(yes, annoying enough to cause headache) problem in next OS update.
To readers.
Sorry to my poor English(I live in Seoul, Korea)

E1200 - Loud Annoying High Pitched Noise.

For some reason the power brick for my Linksys E1200 router makes a loud annoying high pitched noise. Eh.

High pitch noises from AC adapters usually mean a protection component is either vibrating (may or may not be dangerous, depends on how well built the AC adaptor was), or that something is leaking electricity. The power adapter seems not to be functioning properly.

10.4.3 & High Pitched Noise

I just upgraded to 10.4.3 and can hear a high pitched noise coming from the machine itself--not incredibly loud, but somewhat high pitched. I didn't notice this with 10.4.2 or any earlier versions.
- It isn't coming from the speakers (and changes in volume or mute do not affect it).
- Changing brightness on the monitor makes no change to the noise
Anyone else experiencing this or have a solution?

Is that the only thing you upgraded? You did not install any new software? I have a powerbook 1.25 and so far everything seems to be going well it might take a bit longer to start but that's it.

High Pitched Noise When Recording From iSight Camera

I apologize if this has been asked before. I did a search on here as well as with Google.
Whenever I record a video clip using the built in iSight camera I notice that there is a constant high-pitched noise embedded in the clip. You don't hear the noise during recording, and otherwise the audio is crystal clear during playback, but I can't seem to figure out what is causing this noise. Video clips I import into iMovie don't have this problem. Has anyone else experienced this problem? How can I prevent this from happening with future recordings?

Hello obsidianspider
I am sorry to report that you are one of about ten people who have posted here about audio noises during video recordings with MacBooks. I listened to your YouTube clip, and I believe you are hearing something. I can hear the muffled "thumping" of background noises being amplified because there is no voice or other close sound being recorded in your video, but my old ears do not hear anything high pitched in your video (or anywhere else for that matter.)
I am sure Apple is aware of the issue, but with so small a number reporting this issue among thousands of MacBooks sold, I understand why there is not yet a kBase technical article on this subject.
I expect that Apple searches its warranty & repair work for quality issues and trends, but, if you have not (and do not) contact Apple or your retailer for service on this issue, please report your problem via MacBook Feedback so Apple can accurately record the magnitude of this problem. Unlike posting in this user forum, "Feedback" reports go directly to Apple.
We users who post here have found no solution yet, so the problem appears to require professional service for resolution.
However, if you are willing to try a test, please post back and tell us whether video or movie clip recording applications other than Apple's give the same audio noise you hear when using iSight with iMovie. Apple's QuickTime Pro has already been tested and found to exhibit the problem.
If you have access to an external microphone that can be located away from your Mac while you record video, you could also test to see whether you are recording a physical sound coming from your Mac or electronic noise being produced within your Mac's circuitry.
If you want to read the suggestions we have offered for minimizing your audio noise in video recordings, take a look at the suggestions offered in Eemma's thread, which was the first to report this problem. The suggestions for minimizing noise start here:

Portege R700 - high pitched noise

I get a high pitched noise from my Portege R700-11P. The noise is in the upper range of audible sound (maybe around 15'000 Hz) and is periodically increasing and decreasing at a frequency of about 0.5 Hz. It is always there if the laptop is plugged in to the power source and is sleeping, it is sometimes there if the laptop is plugged in and running, and it immediately vanishes if I plug it off. The noise seems to come from the upper left corner of the laptop. It is not very loud, but clearly audible and quite annoying after some time. Anyone knows the reason for this noise and any possibility to get rid of it?
Thanks, Martin

Kojak45, no, I did not solve it, and I am not sure the latest developments will be reassuring for you: after a few months, the laptop sometimes started not waking up from hibernation anymore until it finally completely died. Luckily it was still under warranty, so it was now replaced with a new one. The new one also makes the high pitched noise, but this time only when it is running and plugged in.
Cheers, Martin

Satellite S1800-921: USB - high pitch noise appears

Hi,
I have a Toshiba Satellite S1800-921 Notebook.
Everytime I plug a device in any of the USB ports this high pitch noise appears.
Then when I unplug a USB device the noise disappears.
The noise comes from the back of the laptop where the USB ports are. The noise is very annoying since it's high pitch.
I've disabled the Ali PCI to USB Host Controller device through Device Manager in Windows XP and that seems to stop the noise but then I can't use any USB devices.
Has anyone come across this problem before and does anyone know a solution?
Any information would be most appreciated.
Many Thanks,
Andrew

Hi Jimi,
Thank you for your advice.
I am on Windows XP Service Pack 2 and I'm up-to-date with all my Windows Update Downloads. So the update you recommended is already on my computer. Sorry but the noise is still here!
Thank you for trying though, I appreciate it.
Just to clarify about this "noise". It's high pitch in tone but not particularly loud. Again it only appears when I plug something into a USB Port.
Though when the printer is plugged in it's OK until I put the power switch on the printer and then the noise re-appears.
When the computer is processing something (like opening a MS Word Document or opening a website window) then the noise subsides. But when the computer is idle then the noise reappears again. This drives me nuts because the noise is not only very annoying but it comes on and off continously as I use my computer!
Also, when the noise appears and I'm dial-up onto the internet then there is this interference noise coming through the notebook's loudspeakers.
Anyone got any idea how I could rectify this problem?
Many thanks,
Andrew

Ipod touch 4 creates high pitch noise from cassette adapter

Did not have this issue with my ipod touch 2nd generation.
Have a Monster cassette adapter in my car (looks to be an earlier model than what is currently for sale at Apple website). ipod touch runs off of battery (not plugged into power source).
Creates a high pitch noise through the speakers. Not particularly loud, but annoying and very noticeable during quiet moments of music/podcasts
Volume of noise does not change with changing the volume on the car audio system.
Will start when the ipod touch starts playing. Will persist as long as the ipod is playing. Will not immediately stop when the music is paused. It will stop though after about 10-15 seconds.
Any ideas of what is causing this and why it did not happen with my previous ipod touch (2nd gen)?
Using iOS 4.1

Thanks for the suggestions/questions
If I plug the touch into my wife's car that uses a straight plug-in (no cassette adapter), I don't hear the noise. Unfortunately this is not an option on my car.
Have not tried plugging it into an actual home stereo but can give that a try.
If the engine is shut off, the noise is still present. Unaffected by the engine or RPM of it.
One other clarification - the noise is constant coming from the ipod. It does not vary based on the ipod volume. What this means is that if I turn up the ipod to full volume (and turn down the volume of the car stereo), the noise is less noticeable.
Of course the noise gets amplified with the rest of the music by the car stereo volume.
Will also try other suggestion and see what happens if I turn Airplane mode on.
Thanks
