From: Aerosol emission and superemission during human speech increase with voice loudness
Representative raw data in which a participant (F4) said /ɑ/ for 5 seconds, followed by 15 seconds of nose breathing, repeated 6 times at approximately the same loudness. (A) The amplitude (arb. units) recorded by the microphone versus time. Magnification shows 13 ms of the waveform with fundamental frequency of F0. (B) The corresponding number/concentration of particles measured by the APS versus time.
