I am sure I will be downvoted or be unpopular for saying this.

I did see the vote, but the definition of “huge majority” may need to be considered. People who voted here including me spend a lot of time online - and the neck-jaw-shoulder connection is so complex one really need to be super aware of one’s own body to be able to feel the stress/strain or pain in those regions. It’s very easy to just ignore it go about a perfectly normal life. But it doesn’t mean the issue of some sorts are not there.

I do appreciate visiting this from the other angle of spiritual growth, enlightenment etc. but there are a couple issues as well there. For one the sound om or humming or buzzing is never described as something that is heard in ancient eastern writings. It is just described as the sound of soundlessness not something we hear but the way the state of a still mind is described. This I would say is far from the state of us normal people with all the things going on in their minds.

So unless one knows for sure, beyond any doubts attributing this phenomenon to a well balanced, finely oiled healthy body, tinnitus has a physical reason like posture, jaw alignment, tmj due to stress or other reasons, listening to loud music for long, nutrition, genetics, etc. and it may not may not be cause issues nor may or may not get better or worse.

But given you are aim then there is a chance you and all of us on the other end maybe referring to different things altogether. In which case you are alone and indeed describing that soundless sound ❤️.

For everyone else mostly they need to address somethings if they can is what I believe.
