About

Vistiqa is a medtech company specializing in high-fidelity medical voice CFD simulations. A deep understanding of the physiology of voice production forms the foundation of our long-term mission in medicine: to develop next-generation vocal fold technology – from numerical simulations to patient-specific vocal fold implants.

Our expertise lies in detailed modeling of laryngeal airflow, fluid-structure-acoustic interactions, and computational aeroacoustics. Advanced simulations provide researchers, phoniatricians, and medical device developers with detailed insights into human phonation, enabling them to optimize voice production with exceptional precision.

Computational aeroacoustics allows us to identify and analyze flow-induced sound sources in complex biological systems and propose targeted modifications to improve acoustic performance.

Simulations

We specialize in medical voice CFD: high-fidelity simulation of laryngeal airflow, vocal-fold motion, and the sound they produce. The aim is practical – to understand how geometry, material and flow change the voice, and to support clinics, surgery and the design of next-generation vocal folds.

Key topics

Vocal-fold oscillation
Glottal jet and laryngeal turbulence
Flow-induced voice sound

Core expertise

Large-Eddy Simulation (LES)
Computational Aeroacoustics (CAA)
Fluid-Structure-Acoustic Interaction (FSAI)
Surrogate modeling
Uncertainty Quantification (UQ)
