Pitch
uThe dimension of sound that most closely relates to frequency.
lThe higher the frequency the higher the pitch.
lDiscrimination between two pitches depends on the frequency of the lower pitch:
vWeber Fraction:   (f1 - f2)/f2  =  0.004
ue.g.
v(251-250)/250= 0.004 (1004-1000)/1000=0.004
lPitch is not the same as frequency
uPitch will change as intensity is increase and frequency is kept constant.
