I have asymmetric hearing above 15 kHz. One of my tinnitus tones is extremely high pitched, probably well above 16 kHz. I can hear 16 kHz quite easily on the left ear, and can hear up to 18 kHz or so on the left ear at normal volumes. I have to raise the volume to hear 16 kHz more clearly on the right ear, and I seem to be out at 16.5-17 kHz on the right ear, even at a fairly high volume on my phone frequency generator.
I have read that bimodal stimulation will not work for you if you can't hear your tinnitus frequency.
I'm really worried that MuteButton may not work for me, because I can barely hear my tinnitus frequency out of one ear, if at all. I really don't want to end up with 16-17 kHz+ tinnitus for the rest of my life.
