The human ear canal is much like an organ pipe that is closed at one end (at the tympanic membrane or eardrum) and open at the other. A typical car canal has a length of about 2.4 cm. What are the frequencies of the two lowest resonant mode in this person's ear canal? The speed of sound in air is 343 m/s.
The human outer ear contains a more or less cylindrical cavity called the auditory canal that behaves like a resonant tube to aid in the hearing process. One end terminates at the eardrum (tympanic membrane), while the other opens to the outside. (See (Figure 1).) Typically, this canal is approximately 2.3 cm long. The speed of sound in air is 344 m/s. A) At what frequencies would it resonate in its first two harmonics? Express your answers in kilohertz to...
The human ear canal is approximately 2.6 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. Express your answers using two significant figures. If there is more than one answer, enter them in ascending order separated by commas. What is the relationship of your answer to the information in the graph of Figure 12-6 in the...
