Hello again Laura,
I can speak from my experience only but, taking out more low frequency gain than my “best fit” would indicate from the audiogram helps me and makes voices sound “sharper”.
At 250Hz my loss is only about 30dB, it drops to 50dB at 500Hz, and then falls way down to a 75-80dB loss at 1000Hz and stays there out to 4000Hz.
When aids are programmed to my “best fit”, I get too much “bass” sound. I then have my audi knock out 5-10dB at 250 & 500Hz and things sound much better. Other peoples voices, and mine, sound crisper and sharper.
When you ask about hearing other peoples voices lower, I’m not sure what you mean but if you mean “bassey”, it should be just the opposite. You should be able to up the overall gain just a touch if needed without running into too much feedback (I hope).
Hope this helps you. Please see your audi and try a change. Good Luck!
