It is a very low-frequency vibration that waxes and wanes, like a wave. You didn't forget anything, but I wanted to clarify. 1) You asked if I am sensitive to sounds. This could be interpreted different ways. If you mean, do certain sounds sometimes bother me, then the answer is no (this hum is the VERY first exception in my life - and tinnitus but that is normal). If you are asking... have I historically had acute hearing - the answer is yes - at least up until my first ear surgery at 26. 2) I have, as an adult, come to suspect myself of having ADHD (maybe from my mom). I have also come to believe my dad might have asperger's. 3) A friend has said she heard the hum also, but she couldn't tell me about it. I don't think she heard it - I think she just was trying to make me feel better. 4) I am an interesting breed of person. As one who does have technical training in the sciences, I appreciate immensely the accurate application of science to the fullest degree possible. But the philosopher and psychologist within me know that even science has limits. It is definitely difficult not to start feeling a little bit crazy when you start hearing things no one else can hear. And that makes it difficult to keep yourself out of theories that certain people with certain training might deem as "crazy". But maybe you can tell me how it is that so many people are still so ignorant of so many fairly basic concepts. I have a friend, for example. He is a musician - guitar player, singer, songwriter. He's been doing it for decades. Everyone in St Louis knows who he is (at least in certain blues circles). He has youtube videos, and all the stuff. I consider him a professional in the field of sound. So how come he was 100% oblivious to the fairly well-researched scientific data on sound control on the human psyche? And why is he not alone in that? Why do most of the people I know who consider themselves sound professionals have no clue that is even a thing?

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.
