2A. What is the natural frequency of a female who’s vocal tractis 15cm long, closed at one end and opened at the other.
B. What is the second harmonic in question A:
c. Would the frequency change if both ends were closed with avocal tract of 15cm? if so what would it be: (1) 11.46 (2) 573.3(3) 1146.6 (4) 5.73 The pitch of a 4.5kHz tone= 2259 mels, which is4500 Hz. (2 points)
3) Refer to the 50 phon line, and rank the followingfrequencies: 100Hz, 2000Hz, 7000Hz, and 10,000Hz beginning with themost sensitive frequency (least amount of intensity) to the leastsensitive (most amount of intensity). (2 points)
100Hz___________dB
2000Hz___________dB
7000Hz__________dB
40Hz_________dB
