From: Biomechanics of sound production in high-pitched classical singing
Example of high-pitched phonation of S3. (A) Acoustic spectrogram; (B) three cycles of laryngeal oscillation at t ≈ 1.43 s, showing vocal fold contact area documented with electroglottography (EGG); (C) time-varying glottal area waveform (GAW), as documented by high-speed video (HSV) recording at 20,000 frames per second. The arrows indicate the still HSV frames shown in panel d; (D) HSV frames extracted at the incidents indicated by the arrows in panels B and C. Note the full glottal closure in the third out of the five displayed video frames.
