From: Aerosol emission in professional singing of classical music
Boxplots of the emission rates (left y-axis; bars represent the median for all replications of each task) while sustaining the vowel /aː/ in experiment II for the different vocal loudness conditions piano, mezzo-forte, and forte and voice classifications (baritone (red), tenor (green), alto (blue), soprano (magenta), as denoted in the x-axis). For the different loudness conditions, the medians of maximum sound pressure levels \(L_{AF_{MAX}}\) are also shown (full circles, right y-axis). All symbols and colors correspond to the detailed description given in Fig. 2. (Figure created with matplotlib 3.2.1, http://matplotlib.org) .
