A non rythmical pulse/vibration/ utter torture Nice to see the shaking the head one, im not the only one who looks crazy. If i shake my head at just the right speed the noise disappears? And if i clap then there is a half second delay before the pulse/hum returns. It would be great if we could organize a month where we all report level/absence of hum to see if there is a global pattern, or maybeya moving of the hum!

Write it down while you still remember the details. We will look for the others.
Tell us what you sawIf this reminds you of something a friend or a relative told you once and never mentioned again, send them this page. Reading that a stranger described the same thing is usually the part that helps.
