Agreed. I'm female, but was only 38 when I first heard the hum. It stopped for me for a long time, but this past winter I did get plagued with ultra low frequency vibrations again for a couple of months. My husband and I think this time around it was due to military aircraft flying high above cloud cover. It would be worst around the 3a.m witching hour for these sounds and sounded like thunder that pulses over and over. We are not around any military bases or airports so I don't know why they do some pretty noisy maneuvers over my neighborhood from time to time. Once some really noisy jets flew low over my street and just circled around for awhile. Just what you want on a quiet residential neighborhood, Uncle Sam showing off his toys.

The Hum is very selective, approximately 5% of the population "hear" the noise, almost all are aged 50 or over, and 70% of these are women.
Don't bet on this statistic, just that most of the men that have this issue say nothing.
I don't believe in stats to much.
