There are expensive apps and devices to create notched music or white noise. Fortunately, there are also free YouTube videos with noise notched for different frequencies. Identify your tinnitus frequency using one of the web-based tone generator tests, then find and bookmark the video notched for your frequency.

I like “tinnitusreliever610”. TBH, I haven’t found the notched noise to be any more relief than full spectrum white or pink noise.
