Question

#8

Calculate the first overtone in an ear canal, which resonates like a 2.30 ㎝long tube dosed at one end, by taking air temperature to be 37.0°C. Number Hz

Answer 1

given data

Temperature , T = 37 degree C

calculate the speed of sound at 37 degree C.

= 352.7 m/s

Write the expression for the frequency.

frequency , $f = \frac{nV}{4L}$

for First overtone , substitute n = 3

$f = \frac{3*352.7}{4*0.023}$

f = 11500 Hz
