Digital aids are definitely the most talked about hearing aid these days. They have come a long ways since their induction in the 80's. To explain it simple, digital aids receive sounds and then turn those sounds into digits.

This allows digital hearing aids to filter out annoying background noise that typical analog users complain about. On high end models the digital hearing aid is able to be programmed to the users specifications via the internet. This eliminates the need for multiple trips to the doctor's office to have the device reprogrammed.
