Target is Phonak’s fitting software that audiologists and HA fitters use to fit and program Phonak’s line of Hearing Aids. The settings implemented for me in my Custom Program that I gave the name “Extreme Noise” do indeed reduce the ambient sounds greater than just removing the HAs, though like I said, the reduction is not as great as active noise cancelling as achieved by a headset like Bose quiet comfort headphones. If I subjectively say the Bose reduce 95%, then I’ll say this custom HA program will reduce 50%.
