Don’t expect perfection. Hearing aids are not a “cure all," but are simply one tool to help you hear better. They are not a perfect replacement for normally-functioning ears. Although today’s hearing aids are miles above where they used to be, you might still have trouble hearing in certain situations, such as a noisy restaurant or at a party with a lot of background noise. Keep in mind that even people with very good hearing also still have trouble catching every word of a conversation in these environments.
