Chapter 17, Problem 22P

Ever since seeing Figure 16.22 in the previous chapter, you have been fascinated with the hearing response in humans. You have set up an apparatus that allows you to determine your own threshold of hearing as a function of frequency. After performing the experiment and recording the results, you graph the results, which look like Figure P17.22. You are intrigued by the two dips in the curve at the right-hand side of the graph. You measure carefully and find that the minimum values of these dips occur at 3 800 Hz and 11 500 Hz. Performing some online research, you discover that the outer canal of the human ear can be modeled as an air column open at the outer end and closed at the inner end by the eardrum. You use this information to determine the length of the outer canal in your car.

Blurred answer
Students have asked these similar questions
Certain species of mice have a threshold of hearing below that of humans. Suppose you're sitting on a grassy knoll relaxing in the sunlight on a beautiful spring day out in the country. The air is still, and it's quiet. A bird is on the grass about two meters behind you and makes a faint rustling sound in the grass, and the sound is just barely at the threshold of your hearing. At the same time, the mouse whose hearing threshold is −3dB is somewhere nearby, and the rustling sound is also at the threshold of its hearing. How far (in meters) is the mouse from the bird? (To check your answer, ask yourself if you expected the mouse to be further from or closer to the bird than you. Why?)
Ever since seeing as shown in the previous chapter, you have been fascinated with the hearing response in humans. You have set up an apparatus that allows you to determine your own threshold of hearing as a function of frequency. After performing the experiment and recording the results, you graph the results, which look like as shown. You are intrigued by the two dips in the curve at the right-hand side of the graph. You measure carefully and find that the minimum values of these dips occur at 3 800 Hz and 11 500 Hz. Performing some online research, you discover that the outer canal of the human ear can be modeled as an air columnopen at the outer end and closed at the inner end by the eardrum. You use this information to determine the length of the outer canal in your ear.
Sound is detected when a sound wave causes the eardrum to vibrate (as shown). Typically, the diameter of the eardrum is about 8.4 mm in humans. When someone speaks to you in a normal tone of voice, the sound intensity at your ear is approximately 1.0 × 10-6 W/m2. How much energy is delivered to your eardrum each second?
