Noise problem

I got my MacBookPro end of April. For some time now I have a noise problem which is very annoying. At first I thought it is only in my imagination until it severely intefered with my concentration and even my well-being. It is a high frequency noise which stops when I close the display. The noise seems to go up and down with the screen brightness. After reading through the discussion threads and finding information on the whining-noise - which seems to be a well known issue - I experimented with blowing into the areas where the fans are located and.....surprise, surprise the high frequency noise seems to be gone for the moment. Had anybody similar experiences??? and what would you recommend.

Let's not get overly dramatic... noise affecting your well being? Research will show that if it is truly affecting your well being you fall within the 8% of people that may develop depression, anxiety, or another psychological disorder from everyday stimuli. If you are not being overly dramatic, I would suggest seeing a psychiatrist... seriously, I'm not being a jerk.

This is a known problem, some call it the "Screen Inverter Whine". Faulty screen inverters were present in many of the MBPs released between January 2006 and roughly June 2006.
The solution to the problem is having AppleCare replace your screen inverter.
Call Apple Care and describe your problem. They will handle it by shipping you a box to send to a repair center. Your computer should be out of your hands roughly 3-5 business days depending on shipping times.
Good Luck.

Strange noise problem with music layer after replacing the music file using script in CS6

Hey guys,
I got a strange problem. Sometime when I import a music file, or replace a music footage with another music file using the "replace()" or "importFile()" method, the music layer added one second noise at the beginning. like this,
Does anyone know what's going on here?
I'm using After Effects CS6 windows Server 2008 64bit.
Thanks in advance!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hi Myleniu,
Thanks for your replay. Actually, it doesn't matter what makes up my comp, this problem just randomly happen when I render any comp. For example, I have a comp named "noise", I run a script to replace the music then render it, I use a "for" loop to do this 5 times and the music noise problem just happen one time.
I'm starting to think that win server might be the problem.

Digital Noise Problem on AA 1.5

Adobe Audition 1.5
Lately I have noticed that just by opening a track within Adobe Audition, that process "creates" or embeds digital noise within the song.
I have tested this problem a few times by listening to the song before opening it within Audition. Beforehand, the song plays without digital noise, and after it has been opened within Audition, the noise appears. This digital noise is hard to describe, it's short in length of time, about 1-2 seconds, and will appear at least once within whatever song is being tested.
I uninstalled and reinstalled Audition to see if this would solve the problem, but to my surprise, the exact same digital noise problem remained within the reinstalled version of program. In the past, AA 1.5 has worked okay without this problem.
It's also worth noting that when I reinstalled the program, I successfully entered my program key, and I am "not" running the program in demonstration mode.
I am planning on upgrading to Adobe Audition 3, but the upgrade uses a previous version as a platform on which to upgrade to version 3.
The concern is that this digital noise will "survive" in version 3 of the program.
Thanks for any tips or ways to eliminate the digital noise (besides reinstalling the program), even within Adobe Audition 1.5 for the time being.

The brief digital noise "replaces" or interrupts the song and does not mix together with it.
I have been saving the songs in .wav format.
I operate AA in virtual mode on Windows XP within a Mac computer, and now I have also discovered the same
digital noise on another sound program within a song on the Mac side.
I appreciate that this isn't a Mac forum, but I found a bulletin from Apple about noise issues with my current G5 computer:
http://support.apple.com/kb/TS2033?viewlocale=en_US
Perhaps this is good timing as I am preparing to buy a new Mac Pro, and this one has an Intel processor so I'll be
able to run Windows and Adobe Audition natively.
Thanks to all for the insightful comments and help.

Noise Problems at 100 iso

Hey im a rookie working editing a music video i shot.
From what I was taught about noise. It comes from high iso and underexposed images.
I shot in bright day light at 100 iso and footage has noise problems.
Heres the link to the vid im editing. Its at 17secs(look at the black jacket) and all the way thru.
http://www.youtube.com/watch?v=DJoRdqyE-70
Canon t4i with kit lens. 24fps, 50 shutter speed, Lightform c picture style

That's what I call "codec noise", sadly a known and hard (if possible) to avoid issue with canon VDSLR. Things that might help :
- using an on camera "flat" color profile like flaat10.
- lowering contrast, saturation and sharpening on this profile (the guy behing flaat10 provide good guidelines for his profiles).
- disabling every picture processing options like "highlight priority".
- staying away from the exposure zone were the issue is most visible, ie better plan your lighting and exposure. Being outdoor with a nice sun at 100 iso won't matter if you're shooting people standing in a shadow area with dark clothes. Keep in mind that with this kind of camera you have a very limited dynamic range to work with. Shadow + sunlight will give you nothing but overexposed highlights and muddy shadows.
- not doing the post work in native H264 but rather transcode to something like DNxHD or ProRes (that was usefull with FCP7 and Color, I have no idea how Premiere handle this, never tested and probably never will).
- not letting this drive you crazy. It's quite hard to see in your video and I probably only saw it because I knew what you were talking about before I even watched the video. It is highly improbable that most viewer will notice it.

6120c speaker noise problem

I have puchased Nokia 6120c a month before. It work fine up to my requirement and expectation.
Since last some days, it created noise in the front size speaker and sometimes mutes while listening to some caller. But when I make the volume down, it works fine.
I will be grateful if you please guide me how can be get rid of this inconvenience of speaker noise problem, and suggest me the solution.

Which HD do you have?
1. There is a constant noise from it and by
monitoring the fan sensors it have concluded that
they are not to blame. Altough it sounds like a fan
that is constantly on because it sounds like air
flowing inside the computer. As far as i can tell the
noise seems to be most apparent under the trackpad.
This noise is on from the moment i turn on the
machine until i shut.
It might just be the sound of the hard drive spinning. They don't appear to ever spin down. Especially the 7200 one like I have.
2. I belive or am imagining to my self that the
harddrive is becoming louder when writing/reading
activity.
It not just your imagination runnin away with you. On occasions mine makes some clicks, etc. when reading or writing.
So from these two issues i tought it migh have been
the harddrive that had some fault on it, but i cant
seem to find any, the S.M.A.R.T. status is verified
and there is never any sounds which might suggest bad
sectors on it.
I think it just may be "normal" for these drives.
3. Every 2-3 secconds there is a faint noise from the
PowerBook and i belive that this might have something
to do with the Power as when it is not pluged into
the mains there is no sound. It sounds like a very
quite heartbeat monitor.
No clue what that is.

Is it common for imac 20" isight to have noise problems?

Hi there,
I ordered imac 20" isight and currently waiting for delivery. I am getting woried over these "buzzing noise" and other noise problems reported over and over again here on these boards. Can more experienced users of these boards, apple insiders and anyone else give me your opinion:
Is it common for imac 20" isight to have noise problems?
I am really considering to get 17" if there is any real information it is considerably more quiet.
Thank you in advance.

We have a new 17" and 20"
The 17" is virtually silent, the 20" there is some fan noise.
I find it annoying, although it is 100% quieter than my old PowerMac, which I got used to!

Big fan noise problem: the rear fan won't shut off, the BIOS won't update, systemupdate locks up

I received new ThinkStaion (oh boy, lots of memory and CPU speed, yay!)
I unfortunately left the originally installed Vista OS on there. Very much regretting that as I believe it contributes to the following problems (BIOS).
So the original problem was that after just a month of using my new ThinkStation, the System Board died, and it had to be replaced. Honestly, all I did was choose the sleep or hibernate option in Vista to shut down. Afterwards,poof! didn't even get the proper Power lights on the system. I diagnosed this with the online docs and then sat for a few hours on our tech support line doing all the same things to re-diagnose it.
So after the replacement, the rear fan will not shut off. Jet engine noise all day. I went into the system settings and selected "Quiet" for the Fan settings but that did not help.
Research on this forum resulted in the possibility of a BIOS update fixing the problem. Comparison to my co-workers systems which arrived at the same time shows this BIOS is woefully out of date, so even if it does not fix the fan issue I want to update it. However, everything I've tried to do is failing for one reason or another.
(The fan issue does need resolution since in one week I will end up sharing an office (first time in many years, thanks IBM for nothing!) so since I don't want us both to have to wear noise cancelling headsets, I'd like to fix this without having to just pull the @#$@ power to the fan. Grrrr. )
I downloaded what I felt were the appropriate Lenovo apps to update both the BIOS and the serial number but none seem to work properly from the command line in Vista. One of the two (can't recall which) asks me to reboot and it never actually shuts down. Eternal "Shutting Down" message. Ga! The other throws some gosh awful

Then I decided Vista might be the problem and found sites recommending flashing the BIOS from a bootable USB. So I started down that path and after burning the wrong version, finally geting the AIK Vista tools installed and to the point of trying to make the USB bootable, it won't allow me to put the OS boot on it. Ah, for the days when a simple "sys a:" took care of that.
So, after reformatting the USB and pounding my head in the wall, keyboard, etc. I am at my wit's end. What to do. I just want the fan noise to go away.
This does seem to duplicate other forum messages but I can't get anywhere on this. Help!
Solved!
Go to Solution.

FYI to all the helpful folks here (and any looking to shut their jet engine off as well): Flashing the BIOS did the trick.
First I had to find a website with DOS OS files and put those on the USB instead of Vista. Oldie but a goodie, but at least it booted! No other versions would.
I had been intending to use the WinPhlash utility that Lenovo supplied with the BIOS update but since I was booting from DOS that was useless. However, I found a DOS version of it and used that instead. Boom baby! Flashed and rebooted.
It did take two boots to get it back to normal (first one gave very alarming messages about no operating system being found but I think it was just a remnant of the reboot that was triggered from the DOS session). A second boot returned life to normal and blissful silence from the server. And I was finally able to get the model and serial number back in there to get rid of the bootup message it throws for that too.
Ahhhhhhh.
Thanks to all for the hints - I believe I had gotten the idea of flashing the BIOS to solve this from some other thread I found here. This is a very nice forum to have bookmarked.

Noise problem with HP Photosmart C4480

I purchased this all-in-one in November of last year - now out of warranty and guess what? It has developed a fault in that it makes a noise like a loud machine gun burst before it starts printing. Print quality is still fine. On line technician in a far off place(i think) wasn't much help. Can this be cured?

Hello Wildviolets
If the printer was having noise and now won't work at all then it sounds like the printer may have had a hardware problem. As for the ink if they are Genuine HP ink and you just purchased them they should still be in warranty. If you purchase a new HP printer that doesn't use those cartridges, you should be able to call HP they should be able to replace any unopened ink cartridges that are in warranty for other HP ink cartridges that will work with your new printer.
Hello Larrycza
It does sound good for the printer. Have you tried running the HP Hardware Diagnostic Utility? It may be able to determine which component or problem is occurring.

Don't forgot to say thanks by giving "Kudos" to those that help solve your problems.

Ground Noise Problem Possibly Attributed to Samsung Monitor

I have a Samsung SyncMaster 730b and a 15” Apple Powerbook G4 (1.67 GHz), powered by the standard Apple 65 watt power adapter. I typically connect my Samsung 730b monitor to my Powerbook to use it as a second display connected through a DVI cable. For some reason my power adapter plugged into the Powerbook is turning itself off, which fails to charge my battery and eventually drains the computer to nothing. I am able to get the power adapter to start charging again if I unplug it from the wall and then plug it back in.
I have been troubleshooting the problem for months and have spent a lot of time researching online, including all of the pertinent Apple and Samsung support forums I can find. Apple says that the power adapter shutoff occurs because the AC adapter's over voltage protection feature senses ground noise and turns off the adapter. The company also says that it may not happen if the power adapter is plugged into an uninterruptible power supply (UPS).
I have not tried a UPS yet because it will require a significant purchase and only some users on the support forums have found the UPS to be successful at stopping the power adapter shutoffs. I have reset the PRAM, NVRAM, and PMU that Apple and individual users have suggested and I continue to have the problem. The problem persists no matter what outlets, surge protector, or combination of the two is used for the Powerbook and/or monitor. I normally have additional peripherals connected to my computer, but the problem has persisted without any devices (other than the Samsung monitor) plugged into my computer.
I have had the problem at my current apartment and my previous apartment. I have never had the problem in any other location I have used my laptop, but I have also never used my Samsung monitor in any location other than my current and past apartments. I have connected the laptop to a Westinghouse LCD television for more than a week and used that as a second monitor (to troubleshoot the problem). I have not had a problem with my power adapter while using the Westinghouse as a second monitor. I have only had the problem when my Samsung is connected to my Powerbook. The problem persists whether or not I use a VGA cable with DVI adapter or a straight DVI cable from the monitor to the laptop. The problem does not occur if the monitor is not plugged in to my laptop, regardless of whether or not it is powered on (e.g. my monitor turned on and searching for a signal that isn’t there does not cause the Powerbook to have a problem). The problem also persists whether I set the external monitor to a 60 hz refresh rate or a 75 hz refresh rate.
*To recap, the problem is not solved by:*
-Using a different monitor cable
-Using a different power outlet for the computer
-Using a different power outlet for the monitor
-Using a different power outlet for the surge protector
-Using a different surge protector for the computer
-Using a different surge protector for the monitor
-Bypassing the surge protector and plugging the computer straight into the wall
-Resetting the computer’s PRAM
-Resetting the computer’s NVRAM
-Resetting the computer’s Power Management Unit (PMU)
-Using a different refresh rate on the Samsung monitor
-Unplugging all peripherals from the computer except for the Samsung monitor
-Using the computer and monitor in a completely different apartment (on the other side of town)
*The problem is solved by:*
-Using a non-Samsung LCD TV as a second monitor
-Not using an external monitor
My troubleshooting leads me to believe that the Samsung monitor is causing a problem through its connection to the computer. I do not believe it is a problem with the monitor’s connection to the power outlets in the apartment because the problem does not occur when the monitor is powered on and unconnected to the computer. I therefore do not believe plugging the monitor and/or computer into a UPS will solve the problem.
I do not believe it is possible for the monitor to be sending electrical noise out of itself and into the apartment’s power outlets, but if it is, I have one additional troubleshooting configuration I would try.
I understand this is an elaborate description of my situation, but I hope it is helpful in showing the isolation of variables and troubleshooting actions I have followed. Have any other users encountered a similar problem? What do you believe the problem to be and what suggestions do you have for me to continue using my Samsung monitor?
Thanks in advance for your assistance.

Hey Lou and eww,
Thanks for your quick replies.
The problem started about a year ago in my previous apartment. I do not have any AC line control devices, but I don’t think my current neighbor’s connections are relevant because I had the problem in my previous apartment. My previous apartment was actually a room in a house and that is where my problem first appeared. I had the same setup there as I do in my current apartment, so I counted that as my “second location.” Eww, Are you recommending I try another?
I don’t think I mentioned this in the original post, but my problem doesn’t happen at consistent time or time intervals. It happened about five minutes ago, but that was the first time it happened since I posted on the forum about 14 hours ago. Sometimes the adapter goes off twice in an hour, sometimes it can be several hours or days before it happens.
I am using the grounded three prong cord that attaches to the white apple power block.
If I were to get a new power adapter, I’m thinking the igo juice70 or igo everywhere85. If I were to get a UPS, I’m thinking the APC UPS BE550G or BE550R. Please comment if anyone knows any specifics about these products that probably won’t help my situation. Like I said originally, I am trying to avoid purchases unless I am pretty confident they will solve my problems. I will try to borrow a friend’s power adapter soon and see if that is less sensitive.
Any additional comments or suggestions by anyone are always appreciated! Thanks!

Noise problem on analog channels

I have 18 analog channels connected in differential mode to a 6225 DAQmx card. I am trying to measure 14 pressures and 4 temperatures. I have connected the transducers directly to the AI connectors on my SCB68:s. I have also connected the shields from all transducers to the shields crew on the SCB68 to aviod noise.
My problem is that I still get noise on my analog channels. I have configured the channels using MAX in differential mode. I have read the post "Field wiring an dnoise considerations for analog signals" for a better understanding of analog data aquistion using NI-DAQmx, still I am stuck with my noise.
Can anyone help me? I have ran out of ideas.
I get the best result using an capacitor between the positive and negative terminals on the daq board.
PLEASE HELP!
/Anders

Hi Anders,
Quite unlikely that card is inducing some internal noise.
By selecting the range btw 0 to 1 V, you are only changing the ADC gain settings.
What i suggest is that, you give a standard input of fixed voltage ,say like a dry cell or a function generator to the Analog input and check if you are still getting the kind of noise you are getting with your sensor attatched.
Check this for both the ranges you talk about with suitable inputs.
Now, if you do not get noise, then connect sensor in a suitable single ended mode and see if this gives you a better reading.
If you are still getting noise, then i would suspect for improper chassis grounding
do tell if this solves your problem
Regards
Dev

Noise problem with moving bitmaps

I'm having trouble with the most recent Flash player
(9,0,45,0). When
displaying moving bitmaps, the player sometimes shows
horizontal noise
lines across the image. This doesn't happen on all platforms,
but it
does happen on my customers', so I've got to figure it out.
It happens in the OS X Flash 9.0 IDE, but not on the same
machine within
a browser. It happens on some Windows machines, but not
others. It only
happens with bitmaps; if I trace the bitmap into shapes then
the problem
goes away (no, that's not an option for my application). The
format of
the imported bitmap doesn't matter, nor does whether it is
being moved
with a motion tween or ActionScript. Updating to the latest
Flash player
reduced the effect for my customer, but not completely.
I've made a web page that has the live applet (so you can see
if it
happens on your system), the applet source, and a screen shot
of the
noise effect (when played within the Flash 9.0 IDE). Note
that it took
me about fifty tries to get that screen shot, but while the
applet is
running the noise is quite easy to see since it's so sharp.
You can find
the page here:

Excellent!!! (Well, not excellent that the problem exists,

you're inflicted by it, but that it's at least duplicatable.
It gives me

I'm not even using a BitmapData; I'm just moving a Bitmap

the stage. No ActionScript involved.

Has anyone found any solution for the noise problem for an iMac 21.5"?

I have recently bought a new iMac 21.5" 1TB. There is constant noise which sounds like it comes from the disk drive. It is very loud and annoying and you can hear it 10 ft away even. I took it to the Apple store and of course it is too noisy in the store for them to hear it. I left it at the store for them to check and you guess it, they did not notice any disk drive problem and return back to me. I am not an advanced users and I tell you I am not complaining out of the blue and it is not my imagination. After digging through the community, I seem to find a number of threads indicating that there is noise issue on the iMac.
Now I am worried that I have returned my iMac. If this is not a defect, I am thoroughly disappointed in Apple for designing such a crappy product. How can they let a product like that out?
Before I give up, does anyone out there have any advice? Is my only option now return the unit?

Millions have not had a problem so perhaps yours is due to a bad install. What troubleshooting steps have you done? Restart, reset, restore from backup, restore as new are steps you can take to try and resolve the problem.

Camera Raw noise problem in Photoshop CS6

Opening a Canon .CR2 in Photoshop CS6, Camera Raw generates a significant amount of noise or graininess in the image compared with the simultaneously saved .JPG file. This results in the image from the raw file being of reduced quality. I never had this problem using Photoshop CS5.
Is this the result of some setting being turned on? If so, I have been unable to figure out which one. The only other possibility is that there is a severe flaw in the latest version of the Camera Raw plugin.
Can anyone out there shed any light on this?

You're using a raw converter to increase your access to more control. Among the controls you now have at your disposal are color and luminance noise reduction.
The thing is, what you'll want to do is to develop a set of Camera Raw Defaults that start your conversions off as you would like, then save that default so it pre-sets all the controls for each new image you open. In my case, I have a fair bit of noise reduction dialed-in by default for my Canon EOS-40D images.
You may also want to turn down the default sharpening, which will bring up noise in itself. I've done that as well, as you can see.

Is there any x220 owner who does NOT have a fan noise problem?

Hello All,
I've been browsing the forums occasionally for the past week and noted the "pulsing/whining" problem with the x220. I was wondering, does anyone NOT experience this problem or hear this noise? If so, what is your system's configuration and when did you purchase your laptop?
I'm asking because I really want an x220 and want to know if this is a widespread problem. Thank you for your time.
