As a non-Phonak user just doing my own (Bing) search, it would seem that use of a Roger device to increase signal-to-noise is mainly based on directionality choices, relative proximity of mic to desired sound sources, and volume control of Roger device relative to external HA mics. Here’s a link to the Target 6.2 options for fitting a child with a Roger device and the use of NoiseBlock doesn’t seemed to be mentioned anywhere within the guide settings. https://www.phonakpro.com/content/dam/phonakpro/gc_hq/en/resources/fitting_test/target_fitting_software/documents/Fitting_Guide_Junior_Mode_Target%206.2_210x297_EN_V1.00.pdf
Similarly, the Phonak Roger On Guide does not mention implementing NoiseBlock: https://www.phonakpro.com/content/dam/celum/user_guide_roger_on/PH_User_Guide_Roger_On_92x125_EN_V1.00_029-0874-02.pdf
Along the way, I found a really cool Phonak “configurator” that will allow you to figure out what you need to use a Roger device with other brands of HA’s. For my rechargeable ReSound Quattro 961’s, the configurator tells me that I’d need a ReSound Multi Mic and a Phonak Roger X (FM receiver?) to use my Quattros with a Roger On microphone. Pretty neat! (although someone should tell Phonak that ReSound now has the ONE HA model- it’s not listed as a ReSound choice in the configurator!). Roger Configurator
Don’t know whether ReSound noise control is as sophisticated as Phonak’s NoiseBlock but for relative reference, ReSound’s in-app noise control does a pretty good job of screening out repetitive noises, e.g., vacuum cleaner, exhaust fans, etc. The noise control is available when streaming through my Multi Mic and will greatly reduce repetitive noises heard through both my external mics or my Multi Mic either when using either separately or both together.
Anyone with a Roger device and Phonak HA’s ought to be easily able to test whether NoiseBlock is available as a program setting and has an effect when listening through a Roger device. I’d be interested to know as if you have no in-app control of noise transmitted through a Roger device that would be a small plus towards ReSound in considering what my next set of HA’s should be.
