MECHANICS OF THE INNER EAR II3 



All the nerve ends on these sections therefore receive one 

 shock during the period. 



The relative intensities of the several 

 The relative tones under the third, fourth, and sixth pro- 



intensities visional assumptions are shown in the fol- 



lowing table. 



Having studied the effect of changing the relative intensities 

 of the objective tones in favor of the lower one, we shall now in- 

 vestigate the effect of increasing the intensity of the higher objec- 

 tive tone. The curve in figure 36 represents the function 

 f(x) = sin5.r -f- 2sin8ur. 

 The stirrup movement eight has an am- 

 plitude which is twice the amplitude of 

 the stirrup movement five. The table be- 

 low contains the abscissa and ordinate 

 values of the maxima, minima, and inflec- 

 tion points. 



The combination 

 5 and 8. The 

 amplitude of 8 is 

 greater than of 5
