Summary
The finite element method (FEM) offers a flexible approach to designing and optimizing auditory prostheses. This computational technique overcomes limitations of traditional experiments, enabling better hearing restoration devices.
Area of Science:
- Biomedical Engineering
- Computational Mechanics
Background:
- Auditory prostheses require precise design and optimization of parameters like mass and position.
- Traditional experimental methods for auditory prosthesis design lack repeatability and flexibility.
Purpose of the Study:
- To review recent advances in auditory prosthesis design and optimization using the finite element method (FEM).
- To provide insights into future development directions for auditory prostheses.
Main Methods:
- Literature search on PubMed and Web of Science databases for FEM applications in auditory prosthesis design.
- Analysis of studies involving different ear models and prosthesis parameters.
Main Results:
- The FEM enables computer-based design and optimization of auditory prosthesis parameters.
- FEM simulations allow for convenient modification and evaluation of prosthesis performance post-implantation.
Conclusions:
- The FEM is a valuable tool for designing and optimizing middle ear implants and cochlear implants.
- FEM facilitates exploration of novel strategies for auditory prosthesis development.
