There are no miracles when it comes to the hearing aid. It is basically an amplifier. It makes sounds louder. It cannot presume to clarify confused sounds. The better the amplifier and receiver, the better the quality of sound provided to the ears. But, if you have total hearing loss for a certain frequency, you will never hear that frequency, no matter how much it is amplified. While hearing aids can provide significant help in improving your hearing, they should be considered as only one part of an overall strategy to improve your understanding. Lip reading techniques and studying body language can help increase understanding, particularly in crowded noisy situations.
