I experience a low hum tone in my ears and it's getting progressively worse. It used to be infrequent but now it's more or less constant. It's like as if there is a low hum sound outside. It only happens when everything is very quiet and still then the hum takes over but stops when there is other sound going on when I speak or when the phone rings, or if I turn on the radio.

Could it be too much caffiene? I don't smoke.

The sound is extremely low on the frequency scale,­ between 30 and 80hz and apparantly according to a report that some people are picking up this low frequency sound that other people can't hear.

This is driving me crazy at night when all it quiet, I just dread the quiet at night. I don't hear it when i'm alseep and dreaming.

Would appreciate any help you care to offer.

Thanks so much
