Air-conduction in-the-ear hearing aids are small, battery-powered devices designed to amplify sound for individuals with mild to severe hearing loss. They fit entirely within the outer ear (concha) and use a microphone, amplifier, and speaker to convert sound waves into electrical signals, then re-emerge as audible sound waves directed toward the eardrum.
These devices are typically sold as custom-fitted, prescription items tailored to a user’s specific hearing needs. Regulation varies by jurisdiction, often requiring professional fitting by audiologists or hearing specialists to ensure proper function and comfort.
