Development of a portable vortex whistle device and software to measure vital capacity and airflow for voice evaluation, validated against standard instruments.
Description
The project aims to develop a low-cost, portable vortex whistle device and accompanying signal analysis software to measure vital capacity and phonatory airflow, essential for voice assessment. The vortex whistle provides a frequency proportional to airflow, enabling estimates of respiratory and laryngeal function without expensive equipment. The project includes computational modeling, hardware and software optimization, and validation against standard pneumotachometer-based instruments.
