Sound therapy, narrowed down to the frequencies that need it. Find the tone of your tinnitus, double-click to mask it, and leave it running in your browser.
Set your system volume where you would normally play music, then use the output knob here rather than your system volume. A matched tone sits right on the part of your hearing that is likely already the weakest, so louder is not better. Match the tone, set the volume so you can barely hear your tinnitus over the tone, then double click to mask it. Press Esc to silence everything.
The address bar updates itself as you tune. Bookmark this page once you have a match you trust and it will open with everything exactly as you left it. The link below carries the same thing if you want it on another device.
