Answer:
486.76 Hz ; 1460.29 Hz
Explanation:
Given that :
Length of vocal tract = 17cm
Velocity of sound in air = 331 m/s
The first and second formants of the voice ;
First formants :
F1 = V / 4L
V in m/s ; L in m
F1 = (331 m/s) / (4 * 17/100 m)
F1 = (331 m/s) / 0.68 m)
F1 = 486.76470 Hz
F1 = 486.76 Hz
Second Formants :
F2 = 3V / 4L
V in m/s ; L in m
F2 = (3 * 331 m/s) / (4 * 17/100 m)
F2 = (3 * 331 m/s) / 0.68 m)
F2 = 993 m/s / 0.68 m
F2 = 1460.2941 Hz
F2 = 1460.29 Hz
