Aerodynamic Measurements in the Pediatric Population

Participants will produce a sustained vowel into a mouthpiece (with nose-clip) connected to a PVC tube, with a balloon valve

Incomplete airflow interruption uses a Y-shaped device. The participant produces a sustained /a/ into a mouthpiece and air filter connected to the tube. The tube splits into two tubes distally.

Participant phonates through a mouthpiece into a PVC tube that splits into two paths. One path is connected to an open balloon valve. When the balloon is inflated and blocks the path, air is redirected into the other path which is gated by a one-way valve.
