Relationship between emission rate PM and the maximum sound pressure level LAFMAX for the test conditions of sustained vowel /aː/ (Experiment II) for all three loudness conditions separated by voice classification including linear regression of the logarithmic emission rates (black line). For regression analysis, only medians of PM and LAFMAX of the five replications were used. (Figure created with matplotlib 3.2.1, http://matplotlib.org) .
