Matching my tinnitus frequency and listening to it helps my tinnitus?

I found online where I could find my T frequency and matched it around 8hz. When I listen to that frequency for a couple of minutes and stop I don't notice my T as bad. Is that good?? Should I get a masking hearing aids to help with my T?? Can I use the frequency finder and listen to it for a while to help also until I decide what to do??

 

I found NCH tone generator download and also Tinnitool website. I would guess that after a few minutes I start to notice it. I will contiune to test it and see what kind of results I get. I keep the volume low as possible.
