Aerodynamic Measurements in the Pediatric Population
Sponsor: National Institute on Deafness and Other Communication Disorders (NIDCD)
A observational or N/A phase clinical study on Normal Voice, this trial is actively recruiting participants. The trial is conducted by National Institute on Deafness and Other Communication Disorders (NIDCD) and has accumulated 7 data snapshots since 2025. Longitudinal tracking of this trial contributes to a broader understanding of treatment development timelines.
Study Description(click to expand)The primary goals of this research are to develop noninvasive aerodynamic assessments specific to the pediatric population, and to describe differences between healthy and dysphonic pediatric voices between the ages of 4-17 years. An adult cohort (ages 18-65) will function as a comparison group for incomplete interruption. To account for challenges associated with pediatric data collection, we will modify our current devices and methods of aerodynamic assessment to be better suited for use with the pediatric population and aim to increase measurement reliability in younger subjects. Our proposed modifications include shorter trial times, auditory masking, the use of cheek restraints, and gamification.
After identification of optimal data collection conditions for each method, we will compare these in a large group of children with normal voice. These data will be compared to data from children with vocal fold nodules or polyp. All data will be compiled into a pediatric vocal health database.

Eligibility Summary
The goal of this clinical trial is to create a vocal health database of people aged 4-65 with no diagnosed voice pathology. The main question it aims to answer is: * what is the best way to assess pediatric voices; and, * what are the differences between healthy and dysphonic pediatric voices? Participants will complete one 60 minute session involving one of three types of aerodynamic interruption.
