Summary
A new framework validates computational models for bone conduction (BC) hearing. This approach uses hierarchical data acquisition for more accurate BC simulations and personalized hearing loss treatments.
Area of Science:
- Biomechanics
- Medical Imaging
- Audiology
Background:
- Bone conduction (BC) hearing bypasses outer/middle ear, offering therapeutic options for hearing loss.
- Current computational models lack standardization and experimental validation for personalized BC treatments.
Purpose of the Study:
- Propose a hierarchical validation framework for subject-specific computational models of the human head under BC stimulation.
- Enable systematic data acquisition from intact heads to isolated tissues for model validation.
Main Methods:
- Experimental study on a cadaver head across system, structure, and tissue levels.
- Utilized photon-counting CT and cone-beam CT for anatomical data acquisition.
- Employed laser Doppler vibrometry to measure vibrational responses under varying conditions.
Main Results:
- Photon-counting CT offered superior structural resolution compared to cone-beam CT.
- Vibrational patterns were consistent across structure and tissue levels, allowing resonance frequency comparison.
- Hydration and thickness significantly influenced vibrational behavior.
Conclusions:
- The proposed framework provides a scalable methodology for validating BC models.
- Accurate BC simulations can be achieved by correlating anatomical and functional variability.
- Applications include improved hearing aid design and personalized therapies.
