Air-conduction hearing aids designed for the ear canal amplify sound to help individuals with mild to moderately-severe hearing loss. These devices fit snugly inside the ear canal, using a microphone, amplifier, and speaker to convert and transmit sound waves directly to the eardrum for improved auditory clarity.
These devices are typically sold as custom-fit, prescription-only medical devices, often requiring professional fitting by an audiologist or hearing specialist. Regulation varies by jurisdiction, but they generally fall under hearing aid classifications and may require compliance with safety and performance standards for acoustic amplification.
