What this research studies

This research focuses on improving voice evaluation by accurately measuring respiratory capacity and airflow, which are crucial for assessing voice disorders. The team aims to develop a low-cost, non-mechanical device called a vortex whistle that can provide reliable measurements of vital capacity and phonatory airflow. By combining techniques from voice science, acoustics, and engineering, the researchers will validate this device to ensure it can be used effectively in clinical settings. This approach addresses the current limitations faced by speech-language pathologists due to the high cost of traditional equipment.

Who could benefit from this research

Good fit: Ideal candidates for this research are children aged 0-11 years who may have voice disorders or coordination issues affecting their speech.

Not a fit: Patients who do not have voice disorders or respiratory issues may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a more accessible and affordable method for evaluating voice disorders in children.

How similar studies have performed: While the approach of using a vortex whistle is innovative, similar studies have shown that low-cost devices can successfully measure respiratory parameters in clinical settings.
