Phonak Target Tinnitus Balance

Hello, i am experimenting with the Phonak Target Tinnitus Balance setting on my Phonak P50UP aids. Does anyone use this feature that can help me understand its functionality?

First under the global tuning page, once tinnitus balance is enabled, it want you to select the shape… 3 options are the default set to hearing loss, set to white noise and set to pink noise. Whats the difference between the 3? The first two seem pretty self explanatory but i’ve never heard of pink noise before?

Also on this screen you can increase the gains on the balance? My prescribed tinnitus balance is 79db. What does increasing or decreasing that value do? And adversely, how does altering the high/low balance affect the prescription?

Does tinnitus balance coincide with speech rescue too? Or does it just appear that wau with the graphs on the fine tuning chart?

Any help would be appreciated, thanks.
