Problem 38P Problem 38P

The human ear canal is approximately 2.5 cm long. It is open to the outside and is closed at the other end by the eardrum. Estimate the frequencies (in the audible range) of the standing waves in the ear canal. What is the relationship of your answer to the information in the graph of Fig. 12-6?

Step-by-Step Solution:

Step-by-step solution

Step 1 of 1 </p>

The ear canal can be considered as a closed pipe

Length of the human ear L=2,5x10-2m

Speed of the sound waves v=343m/s

The resonance frequencies for the closed pipe are;

         

The sound waves at the frequencies close to the resonance frequencies of ear canal are heard better.
