Hearing aids are electronic devices designed to amplify sound for people with hearing loss. They work by converting sound waves into electrical signals that are processed and amplified before being transmitted back into the ear.

Some hearing aids also come with additional features such as noise reduction, directional microphones, and Bluetooth connectivity.
