Your T. is most likely somatic like mine. Do you have jaw pain or neck pain? I can make it louder by just touching my face, and when i yawn or eat it will get louder. I have had extrame tightness in my jaw, to the point where talking was too painful, let alone smiling. In the last couple of weeks the tightness had reduced alot (by only have soft foods, i stopped biting my nails, i stopped chewing gum, no more caffeine, no more alcohol, taught myself to stop clenching at night) and my neck pain has dissapeard. I think my neck and jaw muscles messed with the muscles of the eustachian tube because they are crackling and popping when i yawn and i often have pain in my ears, like i have an ear infection, than i go to an ent and get send home because i don't have any infections or any abnormalities in my ears., i also can't do the vavalsa manouver, my ears just won't pop when i try that, it feels like they are completly blocked.. Altough it is slowly getting better ,the pitch of my t is lower at the moment and it alot more easy to handle. All the best to you!
