I am making a hearing aid for a school project, I got a circuit diagram from a site, but I would like modifications to the diagram, thats why I am here for you guys to help me out once more, I would like it to be still as simple, perhaps simpler, maybe more ICs or anything, or even fancy. I would please like to see how modifications can be made on the circuit or it could even be an entirely new circuit suggestion.. I would appreciate all help... Thanks.
