Yeah, the low frequency T I have is very different from my TTTS (thumps & fluttering). Low frequency masking helps. Have you tried "easyjet jet sounds" on youtube? Someone recommended on TT. Taurine is one of many supplements I tried. I didn't think there were any changes in T or sleep.
@gameover I am going to back off a little and see. Technically I don't know if its better or worse. It seems one is lower and the other more prevalent or maybe its drowning it out. However the low hum has more of a subtle feeling to it not thumping but like vibration and faint warmth. Its also only my right ear that has the hum.
