If you’ve been diagnosed with permanent hearing loss, hearing aids may be a solution for you. In fact, there are many hearing aid styles, designs, features and accessories available to suit any preference or activity. All hearing aids have the same basic parts that bring sound into the ear and make it louder. They can help a person with hearing loss hear better in both noisy and quiet settings. They provide the most benefit to people with hearing loss due to sensory cell damage in the inner ear.
