audio speakers and cancer
Hi, I have a question regarding audio speakers and brain cancer. My
brother died of brain cancer several years ago, at about the same age
that I am now, so I am a bit leery of things that might cause an
increase in risk of devloping brain cancer. Anyway, ever since
childhood I have used buzzing sounds or white noise to aid in sleep.
There is just something very soothing about hearing a constant buzz
(or white noise from a program on my PC), and I sleep much better when
the buzz is present. My favorite buzzing sound is actually from the
alarm function of a radio/clock made by General Electric a long time
ago (I would guess the late 1970's), a model C4315A. Well, I have
over the past few months taken up the habit of sleeping with the
speaker of the clock a couple of inches from my ear, because it feels
much more soothing than leaving it several feet away on a table.
The speaker is 3.5 inches wide. So my question is this: does this
1970's, 3.5 inch wide, speaker pose an increased risk of brain cancer
if it is so near my ear for several hours at a time? I read in an old
newsgroup message that MRI's irradiate the head with EM fields that
are several orders of magnitude greater than a speaker could generate,
and nobody has problems with those, but then nobody has an MRI for 7
hours a day every day. Any thoughts? Thanks a lot!
