It seems very unlikely that you would be able to sense those frequencies, except indirectly through something like audible speaker interference.
However, this would be pretty easy to test! Just have a friend call you at random times throughout a 2-hour interval or something, and record every time you think the phone is about to ring, and every time it actually does. If there's a close enough correlation between the two, that's fairly persuasive evidence.

- michaelvoz 10y agoThis is still anecdotal. You would need hundreds of people, also, the very fact that you are expecting calls pollutes that experiment already...
- monocasa 10y agoA large sample size of people isn't necessary to verify the ability. Case in point, the woman who can smell Parkinson's disease, to some ridunculous p-value. http://www.scientificamerican.com/article/one-woman-s-ability-to-sniff-out-parkinson-s-offers-hope-to-sufferers/ http://www.scientificamerican.com/article/one-woman-s-abilit...
- pessimizer 10y agoIt's not anecdotal if it's consistently repeatable. You would only need hundreds of people if you were trying to prove that everyone could do it.
- Iv 10y agoYou can measure the probability of achieving the result at random and determine the statistical significance of your experiment. Being able to successfully anticipate a call within 10 seconds in a 2 hours interval yields a p < 0.01 Some effects published in medical journals have a less convincing p-value.

- greggman 10y agoI'd expect it to be audio-ish. I can hear my Macbook Pro compute. AFAIK there's no moving parts except the fan but certain programs I can audibly hear something going on inside the machine. It's kind of annoying as I wish it was silent. Note I'm not saying I have any special ability. I'm sure if I had a sensitive mic I could amplify the sounds.
- mkesper 10y agoThis could simply be some capacitor or fan issues.
- yourad_io 10y agoFormer Dell XPS 13 Sputnik (9333 model) user checking in. A decent dev machine for $2K-ish, save for a major flaw: "coil whine"[1]. Very annoying when working in silent environments. Frustratingly random as well - for me, backlight on/off, usb connect/disconnect and scrolling on browsers would change the whine frequency noticably. [2] It is possible that you can hear something similar from your MBP - however it is very unlikely that this has anything to do with any of the radios. I miss the good old days when you knew your PC was busy by the HD sounding like a thousand monkeys tap-dancing shakespear.

- huuu 10y ago"It seems very unlikely that you would be able to sense those frequencies" Is this true? What about heat radiation for example. We can feel that. And we can see/sense changes in electromagnetic fields: http://www.nature.com/ncomms/journal/v2/n6/full/ncomms1364.html http://www.nature.com/ncomms/journal/v2/n6/full/ncomms1364.h...
