I listen to music on my laptop with 16ohm high quality MP3 ear phones. In between music tracks or when I pause the music player, I can hear the electronic noises of the computer operations when it accesses applications or when I do something.
This is an old thought ever since multitasking operating systems were created. How do the bits on the processor, memory or in the system bus not occasionally end up blending together and getting mixed up? Obviously, there is signal interference on my laptop motherboard that I can hear through my heads phones? So if I'm listening to music while running the Grid then will it produce more work unit bit errors then if I have nothing running on my computer at all? Even more messed up what if the music could somehow get encoded into the world unit? Lol, What if the motherboard is really el cheapo? I'm saying we are using resources that nobody has used for supercomputing like projects? Seems there is some potential for weird things to happen and anything man-made will always have flaws. Although very rare, I've seen some really weird things happen will electronics that defy explanations. |

The music you are listening to is in the 20 to 20Khz frequency range, although most of us can't hear above about 13Khz.
----------------------------------------Various parts of your computer also operate in this range, primarily the fans and hard drive. What you are hearing in the quiet parts of your music is the background noise created by the computer components, most likely the hard drive, which is being picked up by poorly shielded wiring in your computer. I've never seen an EMI shield available for a laptop hard drive, and don't know how effective one would be for this condition. ---------------------------------------- [Edit 1 times, last edit by jal2 at Dec 16, 2007 8:30:12 PM] |

Thanks for the response. Yep, after listening to the electronic noise and watching the hard drive light they seem to coincide at the same time perfectly. However, I do hear a more faint annoying constant hum in the background even when it's not accessing the hard drive. That might just be from amplification going to the ear phone plug?
Man, this is an HP dv9500t computer. Maybe, they are cheaper made then most? |

Hmm...maybe, the appliance came in contact with some ectoplasm or something? I'm not sure as I never seen anything that weird. I used to be able to key the mic on a Motorola Saber radio and if close enough it would turn off the CRT computer monitors. It would also turn on the windshield wipers on a 1996 Dodge Dakota if placed near the vehicle dashboard and keyed. I seen a malfunctioning Motorola Razor cell phone that displayed alien looking pictures at random. A wireless door alarms that would go off only during night on occasion. I had a whistler radar detector that would give a 'VG2' alert every time a stealth F-117a would fly over or get in visual sight of my vehicle...lol A Samsung microwave oven that would turn itself on at random for a few minutes. It turned out the Samsung microwave oven had a recall on a faulty keypad. My friend thought a ghost was turning it on. It's always best to keep an open mind before assuming an appliance might be haunted, possessed or came in contact with some ectoplasm. That VCR thing is definitely weird...there is always a psychology behind things also :) Some things could all be in the mind! |
