Reverse cookie bite fitting with ReSound Nexia

Hearing Aid Self-Fitting and Adjusting [DIY]

Trying to nail down the settings. Taking the reverse slope programming advice to cut the lows (counterintuitive to standard approaches). Speech still not great with Audiogram+ but if I increase the mids and highs, fan noise turns into white noise similar to the tinnitus feature.

I downloaded Genie 2 to see what VAC+ gains would be and white noise was a big issue. Really had to scale it back down to Audiogram+ targets (5-10 dB decrease for soft sounds). Tried open domes and tulips. Reverse slope articles suggest it’s a tough balance for venting.

Any advice from others in the same situation?

my audiogram is not to different than yours,(OK it is not the same) :slight_smile: I don’t call it reverse cookie bite … I also have nexia.
I find that a acrylic custom mold with no vent or a very small pressure vent works best for me.

There is a setting for that, Advanced Features >> Custom >> Expansion :
