Ear Gear-microphone attenuation?

I’m guessing Ear Gear attenuates the microphones somewhat. I’m guessing that because they seem to eliminate feedback and they seem to reduce the lows (but that could be my imagination) Anybody have any idea what kind of numbers might be involved? (How many dB attenuation and is it even across all frequencies) If it’s significant, it seems like it would be worth redoing REM. Anybody played with this?

Might not only be mic attenuation, increasing the mass of the HA while changing surface damping will have effects on the transfer function too. One of the biggest problems of BTE is damping the waggle of receivers at saturated output levels.

RIC on the other hand would mainly be subject to acoustic mic screening.

The hearing aid I tried it on is a RIC.
