I have a question about the “ticking” sound that audio speakers make when a cell phone is about to ring. I assume that the noise is caused by EMI - electromagnetic interference. My question, which comes by way of a question posed by J. Michael Straczynski to usenet, is paraphrased as follows:
Straczynski said that he is “one of those people who often seems to know when the phone is going to ring.” He also recognizes that this could be, in his words, “synchronicity”. IOW there are many times he looks at a phone and when it doesn’t ring, it doesn’t occur to him to remember that.
So the question is, can the human nervous system be sensitive enough to pick up the EMI from a cell phone? If it is, it might provide a scientific answer to how some people “just know” the phone is about to ring.
I (he) (we) need the Straight Dope.
