Chapter 16, Problem 33P
The first formant of your vocal system can be modeled as the resonance of an open-closed tube, the closed end being your vocal cords and the open end your lips. Estimate the frequency of the first formant from the graph of Figure 16.23, and then estimate the length of the tube of which this is a resonance. Does your result seem reasonable?

A violin string ? = 31.6 cm long and ? = 0.65 g⁄m linear mass density is tuned to play a La4 note at 440.0 Hz. This means that the string is at its fundamental oscillation mode, that is, you will be on that note without placing a finger on it. From this information:
B. If the midpoint of the chord is displaced 1.80 mm transversely when found in the fundamental mode, what is the maximum speed ??á? of the midpoint of string?
Parasaurolophus was a dinosaur whose distinguishing feature was a hollow crest on the head. The 1.5-m-long hollow tube in the crest had connectionsto the nose and throat, leading some investigators to hypothesize that the tube was a resonant chamber for vocalization. If you model the tube as an open-closed system, what are the first three resonant frequencies? Assume a speed of sound of 350 m/s.

The 1.5 m long hollow tub inside of this crest hadconnections to the throat, leading some paleontologists to guess that the tube was used as aresonant chamber in vocalization.

- When you blow over the edge of a pan flute pipe, a certain tone is produced. Assume that the tube is cylindrical, open at the top and closed at the bottom.

From this information: When playing the violin, different notes may be produced depending on the position of the the fingers of one hand on the string. The usual technique forcefully presses the string against the fingerboard, reducing the length of the string that can vibrate.
