mations to the amplitudes we take the highest ordinate for the 1st, 2d, 

 and 6th component, and | of it for the others. We thus obtain the final

The curves of the compo-

In spite of the amplitude 

 given to the fundamental, it is 

 evident that this tone should 

 be much more strongly repre- 

 sented, for the reason so often 

 repeated that this tone is heard 

 to be the strongest of all and 

 that the series of puffs from 

 the glottis is the most energetic 

 part of the vocal action. The 

 glottal puffs may — as in this 

 case — have a great degree of 

 suddenness (p. 116). The sud- 

 denness will show itself in the 

 curve in the same v/ay as fric- 

 tion. We would be quite justi- 

 Fio. 138.— Component curves of figure 130. fled not simply in exaggerating 



the component found for the fundamental but also in changing its form. 



This is indicated by the dotted line in figure 138.
