Determination of optimal excitation patterns for local mechanical inner ear stimulation using a physiologically-based...

Area of Science:

• Biomedical Engineering
• Auditory Neuroscience
• Medical Devices

Background:

• Patients with residual hearing benefit from combined hearing aid and cochlear implant use.
• Current research lacks understanding of optimal acoustic stimulation from within the inner ear for bionic interfaces.

Purpose of the Study:

• To present a physiologically-based inner ear model for analyzing local acoustic/mechanical stimulation.
• To investigate optimal stimulation parameters at the bionic interface.

Main Methods:

• Development of a simple, physiologically-based inner ear model.
• Analysis of the model to validate its ability to replicate known mechanical phenomena.
• Simulation of local acoustic/mechanical stimulation within the model.

Main Results:

• The developed inner ear model accurately mirrors known mechanical phenomena of local stimulation.
• The model demonstrates the impact of amplitude and phase shift on stimulation outcomes.

Conclusions:

• The presented model is suitable for analyzing local acoustic stimulation in hearing prosthetics.
• Optimal amplitude and phase shift values for inner ear stimulation can be determined using this model.
