I do not like the THI measurement much, maybe it's not too precise. I know it's subjective, like tinnitus. For example, I have between 78 and 88 points on the THI. The description for that number of points says:
"78-100 Catastrophic: Always heard, disturbed sleep patterns, difficulty with any activity."
However, in my case I do not always hear my tinnitus (in my first months yes, but luckily not always now). Although the other affirmations are correct. That is, my tinnitus causes me a lot of anxiety, stress and sadness, fear that it will get worse, however, I do not think it is as loud as the tinnitus of other folks on Tinnitus Talk.
I do not know if I explain myself well. But considering that Lenire is about lowering the volume of our tinnitus or improving it... THI seems to be imprecise but perhaps there is no better way to measure this.
