Two of my tinnitus noises are just like that; high frequency pitch and very low subwoofer like hum.
I know where the high pitched noise originated from (chiropractic treatment gone wrong) and have a theory, or more like an observation, when it comes to the low frequency hum, and I would like to know if maybe you have observed something similar in regards to your low tinnitus noise.
First of all, my low humming or buzzing noise is there all the time. However, I have noticed that over the course of the day it infrequently seems to get some kind of an extra kick.
This is what I have observed:
I live next to a reasonably busy street. The house I live in is separated from the street by a pavement that is approximately 60cm / 2feet wide, so not very wide at all. When there is a steady stream of cars my humming sound remains pretty much the same. If there is an ebb to the cars, though, my tinnitus seems get spiked every once in a while for no obvious reason. However, half a minute / a minute after the spike there almost always is car driving by.
What I've been wondering is the following: Could it be possible that the rolling friction / the vibrations created by cars may travel along the surface material of a road (a bit like rails giving of a humming sound way before the actual train can be seen) and, because it is all connected: street, pavement, wall, create some kind of sonar wave that people who suffer from tinnitus are more likely to pick up on?
Maybe that's just me trying to find an explanation where nothing is to be found, but if somebody here has made similar observations, I'd be happy hear their thoughts. And everybody else's thoughts, too, of course
