While hearing aids can't reverse neural changes, they can help the brain better process the sounds that it does receive.
The brain has a certain plasticity that can learn to interpret sounds more effectively with the help of hearing aids,
thereby partially compensating for the changes in neural pathways. It doesn't necessarily "fill in" the missing audio,
but actually, thru amplification, improves the brain's ability to process speech and other sounds, even if the neural pathways
are not as efficient as they once were. The brain learns to interpret the amplified signals more effectively,
which can improve comprehension and the ability to distinguish sounds in complex auditory environments.
