Relationship between emission rate \(P_M\) and the maximum sound pressure level \(L_{AF_{MAX}}\) 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 \(P_M\) and \(L_{AF_{MAX}}\) of the five replications were used. (Figure created with matplotlib 3.2.1, http://matplotlib.org) .
