Sound generation in human phonation and the underlying fluid-structure-acoustic interaction that describes the sound production mechanism are not fully understood. A previous experimental study, with a silicone made vocal fold model connected to a straight vocal tract pipe of fixed length, showed that vibroacoustic coupling can cause a deviation in the vocal fold vibration frequency. This occurred when the fundamental frequency of the vocal fold motion was close to the lowest acoustic resonance frequency of the pipe.

- The filtering technique improves the detection and correction of errors and outliers in the time derivative of incompressible pressure related to human voice production.
- This method addresses issues arising from the velocity field's divergence-free constraint, especially with non-conserving vocal fold motions.
- By utilizing a random process to identify rare pressure events, it enhances data quality and assists in assessing the convergence of aeroacoustic source terms in large eddy simulations.
