Given the issues above; there’s more to this than meets the eye.
Firstly, any program is going to recommend barely any gain due to the flat audiogram.
Secondly: the dome/mould recommendation will likely be very open -which will disappear any low frequency output.
Thirdly: Given the risk of hyperacusis, I’d perhaps wind down ALL the G90 (high) levels too.
I’m not saying you should ‘throw away the playbook’ but…….
1, Turn off the loud outputs (g90)
2, Try tulip domes.
3, Tell the SW you are using moulds (which allows you to invoke sounds below 1KHZ).
4, Put in a flat gain across all frequencies (with some extra in the LF if you’ve got large canal).
5, Add 2nd and 3rd programs based on P1 with a couple more dB gain on each frequency.
Doing this allows you to toggle between your preference without over egging the level. Just keep the loudness in check, plus you can add in more base when it suits.
Edit: That’ll be $500. Mainly for the nearly 3 decades of experience, professional fees, public liability insurance, treatment insurance, shop rent and rates.
