It certainly isn't !!!! Trust me I have had tinnitus for 30 years and have loud ringing and high pitch static noise. Somehow I coped with those but now I have a low frequency pounding vibrating noise. n can tell you it is another level of awfulness. Ruined my life . Everyday is misery .I think the one that matches with external noises such as outdoors ambience noise. That masks it better.
I think low frequency tinnitus is easier to deal with.
If its both loud and low pitched, i don't envy that person
Ultra high frequencies ie 10-16khz I've also found can sit above almost all background noise. These are the worst, in my opinion. They don't tend pack a lot of punch but they drill into your brain.
