Synthetic, self-oscillating vocal fold models for voice production researcha)

Area of Science:

• Bioacoustics
• Fluid dynamics
• Biomaterials science

Background:

• Human voice production relies on complex interactions between airflow, vocal fold vibration, and acoustics.
• Synthetic, self-oscillating vocal fold models have been crucial for studying these phenomena over the last 30 years.

Purpose of the Study:

• To review and compare two main types of synthetic vocal fold models: membranous and elastic solid.
• To discuss their designs, capabilities, limitations, fabrication, and applications in phonation research.

Main Methods:

• Review of existing literature on membranous (e.g., latex tube) and elastic solid (e.g., silicone) vocal fold models.
• Analysis of fabrication processes, materials, and experimental techniques used with these models.
• Survey of applications in studying phonation mechanics.

Main Results:

• Two primary model types exist: membranous and elastic solid, each with distinct characteristics.
• Elastic solid models offer multi-layered designs to mimic vocal fold tissue complexity.
• Various experimental setups have been employed to investigate phonation principles using these models.

Conclusions:

• Synthetic vocal fold models are vital tools for understanding voice production.
• Further development is recommended to enhance model realism and clinical applicability.
• Continued research can lead to more lifelike vocal fold simulations.
