tl;dr my dad is broke and almost deaf, hearing aids are expencive as shit so i was thinking about making him a pair myself.
i found a DSP for it, the RHYTHM SB3231 from On Semi.
onsemi.com
the diagram doesn't look too complicated but the website is messy and i can't find the programing software for it.
does any of you have some experience with it ?
First--what country are you in?...
In the USA hearing aids are horribly expensive because they must pass AMA testing to qualify for Medicare payment. So a lousy one costs $500 and a good one costs $2000.
There are really cheap "hearing amplifiers" sold china-direct, on aliexpress and the like. These probably aren't the best ones around but they might be good enough, and they cost $20-$50.
nah they sucks, they're basically just op-amps in a small form factor.
there is no filtering, noise reduction or anything.
hearing aids are shit tech
what you want is a electrode feeding pulses straight to the cochlear nerve
What is the signal chain for a hearing aid?
I don't have the necessary skills for that.

where there's a will there's a way
Let's assume that OP doesn't have the will to perform amateur kitchen-counter neurosurgery on dear old dad. This is Zig Forums, not /darwinawards/.
That tbh
