Hissing Noise When Hot?

My Macbook Air makes a hissing noise when running hot (a fan?) when running Garageband for a long time (1/2 hour or more). Will it hurt anything to continue running Garageband while it iz doing this?

The processor is designed to shut down before it gets dangerously hot. As well as the fan is designed to run at a maximum speed that will not hurt the fan. The system will protect itself.   Reguardless, what the last posted said. The fan will run at a maximum of 6000rpm when you are runnning processor intensive programs, GarageBand being one of those programs.  Many games and long HD movies will also do this. Nothing to worry about, just the computer working as it should.

  • Odd hissing noise when inserting PCMCIA card

    I'm testing a wireless broadband card (Sierra AC580), and I've encountered a very strange issue. When I insert the PCMCIA card into its slot, I get a loud hissing noise from the left speaker. I can reduce the volume of the noise by moving the card side to side, and sometimes I can transfer it from the left to the right speaker.
    Is this some kind of interference issue between the speakers and the cell signal coming from the card? Has anyone else encountered this? The speaker volume has no effect on the volume of the sound. Neither does the mute button (F3).

    I have the same sound - my MBP is only a week old as well... If you are not happy with it or are having further problems with it reading cd's or dvd'd then you should take it back to your local apple store.
    I know of two other MBP users and they have the same thing... as said on other posts "not very pleasing to the ear"...

  • Hissing noise when using in-ear earphones

    I decided to upgrade from the Apple standard earphones of the Shuffle to some noise isolating in-ear earphones. Since the top range stuff (Shure, Etymotic) didnt quite fit into my budget I bought a pair of Creative EP-630 ($30) since I read some decent reviews on Amazon.
    Now the earphones do live up to my expectations and deliver some great sound but the combination with the Shuffle gives me quite a headache. Plugging the earphones into my computer or some other (low budget) mp3 players they sound awesome, there is no background noise whatsoever and between songs or when you hit 'Pause' there is silence as it is supposed to be.
    When I plug them into my shuffle however, it is far from the 'chrystal clear sound' that I expected. First, when you turn on the Shuffle, you hear two high pitched feeps, when you turn it of, you get a short stakkato of feeps that reminds me of the dial in procedure of old computer modems for the anlogue telephone line.
    The biggest problem is of course the noise during playback, there is a constant high pitched, hissing, feeping background noise which becomes especially obvious during quiet parts, between songs and even if you hit 'Pause'! The same thing is described at the following site for another pair of (high quality) in-ear earphones:
    http://forum.ecoustics.com/bbs/messages/15118/163354.html
    The author there describes it as a 'grasshopper' noise, which is very much to the point when you hear it.
    This is quite a disturbing result, considering all the raving reviews that Shuffle got for audio quality:
    http://www.pcmag.com/article2/0,1895,1777890,00.asp
    Now I am wondering if there is a faulty batch of Shuffles out there of which I happen to own one, or is it possible that there is a general problem of the Shuffle working together with these kind of earphones? The Shuffle using other earphones sounds great and my new in-ear earphones using other players also sound great... just the combination delivers unbearable audio.
    I would appreciate any feedback, especially if anybody from Apple happens to come across this post!

    Sounds like unless I misunderstand that it's only a problem with non standard headphones. What others are you using?

  • Muvo N200 hissing noise when encod

    I recorded a 60 kbps MP3 sample, with NO audio source connected to the line-in connector.
    Spectral display of recorded MP3 file shows +20 dB over noise floor spectral lines at 7700 Hz (left channel) and 9000 Hz (right channel), clearly audible.
    When audio input was applied, spectral display shows distinct spectrum aliasing around the above mentioned frequencies.
    This means that usable audio band without aliasing effects is limited to 4 KHz, which is enough for voice recordings but clearly unacceptable for music recordings.
    Subsequent recordings show that these aliasing frequencies vary from 7500 to 0000 hz, always audible.
    I find this highly unacceptable from a quality product like this, so I ask if anybody else has experienced this problem and if the technical support has a clear explanation for this.
    Regards
    Maxm

    I would like to see an improved mic in a future model, so that students can adequately record lectures given in large lecture halls. Perhaps the line in could be removed from the standard model, and a premiun model released with a very high quality line in? Most people don't need a line in, however if a line in is provided, then it should be very high quality.

  • Noise when using headphones with new Lumia 630

    I've got a new Lumia 630 today and when I tried to use headphones with it at first phone did not recognize them ( I still have to reconnect them sometimes) but the main problem is a hiss noise when phone produces sounds. It could be music, video or keyboard clicks, whatever. I can hear it even when loudness of music player is set to 0. Is it known issue? Or is it problem with my phone? I tried another headphones and have the same problem, maybe a less noise.
    Sorry for my English. Need your help!

    Hi wtfwithmyphone,
    Welcome to the forum! 
    Does it only happen when using the phone with headsets? Do you also hear this noise when the audio is played via loudspeaker? What are the models of the headsets that you tried with your Nokia Lumia 630?
    Note that the Nokia Lumia 630 supports headsets that have American Headset Jack (AHJ) ports. Using other types of headsets may cause performance issues, like background noise and audio quality distortion. This link will show you some of the headset models supported by the Lumia 630: Accessories for Lumia 630 - Headsets.
    Let us know if this information has helped you.

  • Hissing noise on aux port

    Is anyone having any issues with a loud hissing noise when listening to music in the car using the aux port and a 3.5mm jack cable. I have an iphone 4 and there is no problem but when i plug in my iphone4s i can barely hear the music unless both radio and phone are at full volume.

    I have exactly the same problem. 
    I have an ipod touch = it works fine.
    I had an ipod classic = it worked fine.
    (I have even tried a dreaded android phone from samsung) = worked fine.
    Now I have also tried two different iphone 4s = loud hissing.
    I have also tried a latest generation ipod nano = hissing.
    So I bought new cables for the car. An expensive shielded one.. = no change (lots of hissing)
    The only other alternative suggestion I've found in the web is a aux-style jack connector to the iphone interface, which appears to work for most folks but then it won't be possible to charge my iphone and listen to music at the same time.
    Arghhh!

  • Hissing noise in monitors when plugging external lcd

    Hi,
    this is a bit off topic, but it's logic related in a way ..
    When using an external monitor (lcd), as soon as the metal from the monitor plug touches my macbook pro dvi jack, my (audio) monitors produces a hissing noise.
    The power bar i'm using is plugged in a wall outlet that has no ground. I assumed the bad grounding was the problem, but making a connection with a metal wire between my macbook and a copper pipe didn't help. I think if the grounding was the reason of the hissing, that should have solved, althought temporarly, my problem...
    does that ring a bell to anyone ?
    thanks in advance..

    Hi jukea and welcome!
    Wow, thats a tough one. First, make sure you don't have any audio cables laying on top of your power supplies/AC power in general. Check all audio cables in-line. Some audio monitors may not have adequate RF shielding, so move your monitors away from the display if you can. If this is a permanent setup and the power can not be helped, I would get and ISO box to loop through before I connected my audio monitors.
    Maybe:

    Or:

    You would need 2 of those, for stereo inputs.
    Good Luck!

  • Hiss noise from iPad2 speakers when launching an app that uses the speakers

    A couple of months ago I bought an iPad2 Wi-Fi. It was working fine until yesterday that it started making a hiss noise every time an app that uses the speakers was launched, for example when the keyboard clicks sound is enabled it will make noise while typing (this is somehow annoying). Is this a known issue?
    Is this a hardware defect or can it be fixed with a software upgrade?
    Thanks.

    i have the same problem: ipad2 makes noise every time when plays sound (music, video, games, typing)
    i'm sure that problem is hardware..
    the noise exists only with speaker: if i connect headphones noise disappears

  • I bought a ibook G4 2005 refur-ed it is making a fan running noise when I listen to sample music on line and it will not stop until I reboot.. What could that be also bottom of computer very hot?

    I bought a ibook G4 2005 refur-ed it is making a fan running noise when I listen to sample music on line and it will not stop until I reboot.. What could that be also bottom of computer very hot?

    When my iBook got hot like that, I would take a break and let it cool down.
    You can buy laptop desks that have USB powered fans on them, such as the Targus Chill Mat.

  • Why do I get hissing sound when charging my Macbook Pro

    Hello!
    Few weeks ago i noticed that on my speakers there is this hissing sound/noise coming out, but eventually it stopped. But now I changed speakers to active studio monitors and I hear hissing very well, the hissing noice is just horrible and i noticed that it only happens when I am charging my Macbook.
    And one more strange thing, hissing noise doesn't happen when i use my headphones.
    Has anybody encountered

    I suggest an appointment at an Apple store genius bar for a free evaluation.
    Perhaps an Apple Hardware Test may provide a clue:

  • Hissing noise from rear of mac pro

    Hi,
    My new Mac Pro has a hissing noise at the back of the tower, where the power lead goes in. Is it a power supply problem? Anyone out there with a similar problem?
    Mac Pro   Mac OS X (10.4.8)  

    Hello, thanks for the responses!
    x4...: Haven't tried using another account; my computer has only one registered currently (it's spanking new)
    I did try logging into safe mode - while I received no indication that it was on safe mode, all sound functions appeared to be terminated when I logged on after long-pressing Shift. Panicked in a small way there, ha ha.
    Bart..: Quitting email clients (mail, gmail, outlook on web) didn't help
    And nope - no one else logged into computer.
    All this said, the sound has stopped mysteriously right now. There's a good chance it'll start again though (it's done this before, with no connection to newly opened programmes or anything)
    Thanks, all!

  • Static noises when calling normal?

    i have been experiencing static noises when making phone calls. im the only one who can hear them and not the person im calling.(already confirmed myself.) is the at&t service or is the iphone defected. i hear the static through the normal earpiece at the top(not headset) and in speaker mode. thanks.

    Hi all,
    Mine does it too. Has nothing to do whatsoever with at&t. None of my other phones do this.
    I have a hiss sound I can hear in my earpiece that kind of overlays each word I speak.
    I have posted 2 other threads here and only Allan Sampson has responded and understood what I was describing.
    The information I have gathered online points to the fact that all NON 3 G phones have a poor sound quality compared to a 3G phone of any make.
    Or maybe some of us just have bad ear piece speakers. If so chalk this iPhone up as bad returned iPhone #5.

  • Macbook pro makes a lot of noise when its is on.

    Macbook Pro makes a lot of noise when its being used. It is the sound of the processor and it gets very hot at the bottom of the laptop. Any sugestions for why this is happening? Any solutions??

    Hi p,
    The CPU doesn't make noise, so it's probably fans you're hearing, which would correspond with the heat you're feeling. Read this link to see if there's a process running too high:

  • Getting rid of background noise when recording cassettes

    How do I get rid of the hissing background noise when I transfer cassettes into GB?

    portercm wrote:
    Thanks - this is totally new to me. What sort of software do I need to clean up the noise after the fact? I'm dealing with old cassettes and a cassette player with no dolby option.
    there's a bunch of applications that will clean up or "restore" noisy audio, and they range a lot in price and features. Here's a few options:
    Bias makes Soundsoap 2 (around $100) and Soundsoap Pro (around $550). Bias makes some great audio software, so Soundsoap 2 might be more than adequate.

    If you think you might want to use Roxio's Toast 10 Titanium Pro (around $115), it comes with a version of Soundsoap included. As long as you don't need the features of a dedicated noise removal application, it's a pretty good deal:

    To get a sense of what's out there, here's a selection of noise reduction apps from Sweetwater's site:
