Bone Conduction Hearing Aids: The 2025 Complete Guide
Bone conduction hearing aids
Bone conduction hearing aids amplify sound via bone conduction, or vibrations through the bones of the skull.
There are several different manufacturers and types of bone conduction hearing aids systems on the market today.
Nonsurgical devices are worn on a headband or attached directly to the skin with adhesive.
Surgical devices include an internal component and an external processor.
How Bone Conduction Works
Bone conduction hearing aids (BCHAs) bypass damaged outer/middle ears by transmitting sound vibrations directly through cranial bones to the cochlea.
Key advancements in2025 include:
Frequency range expansion: 250Hz–10kHz coverage (ISO 2025 Standard)
Hybrid transduction: 15–25% more efficient than air conduction via graphene-enhanced transducers
AI-powered calibration: Real-time vibration adjustment based on skull density scans
Clinical Validation:
WHO 2024 trials show 89% satisfaction among conductive hearing loss patients, with 40% faster neural adaptation vs. traditional aids
