Question

According to the "commonsense view" of perception: it is impossible to have an experience of a cricket-like sound unless a cricket is making the sound you are hearing when you stop observing a rabbit on your lawn, the rabbit remains where it was for up to an hour by way of our sense organs, external things cause us to have beliefs that are fairly accurate if I have a false belief, that is always the result of a faulty sense organ.

the-sound-of-a-dinosaur-modern-day-animals-make-extensive-use-of-sounds-in-their-interactions-with-3

The Sound of a Dinosaur Modern-day animals make extensive use of sounds in their interactions with others. Some sounds are meant primarily for members of the same species, like the cooing calls of a pair of doves, the longrange infrasound communication between elephants, or the songs of the humpback whale. Other sounds may be used as a threat to other species, such as the rattle of a rattlesnake or the roar of a lion. There is little doubt that extinct animals used sounds in much the same ways. But how can we ever hear the call of a long-vanished animal like a dinosaur when sounds don't fossilize? In some cases, basic physics may have the answer. Consider, for example, the long-crested, duck-billed dinosaur Parasaurolophus walkeri, which roamed the Earth 75 million years ago. This dinosaur, shown in FlGURE $14-54$ (a), possessed the largest crest of any duck bill-so long, in fact, that there was a notch in $P .$ walkeri's spine to make room for the crest when its head was tilted backward. Many paleontologists believe the air passages in the dinosaur's crest acted like bent organ pipes open at both ends, and that they produced sounds $P .$ walkeri used to communicate with others of its kind. As air was forced through the passages, the predominant sound they produced would be the fundamental standing wave, with a small admixture of higher harmonics as well. The frequencies of these standing waves can be determined with basic physical principles. FlGuRE $14-54(\mathrm{b})$ presents a plot of the lowest ten harmonics of a pipe that is open at both ends as a function of the length of the pipe. Suppose the fundamental frequency of a particular female was 74 Hz. What was the length of the air passages in this female's crest? $$ \begin{array}{lllll}{\text { A. } 1.2 \mathrm{m}} & {\text { B. } 2.3 \mathrm{m}} & {\text { C. } 2.7 \mathrm{m}} & {\text { D. } 4.6 \mathrm{m}}\end{array} $$

Suppose the air passages in a certain $P$ . walkeri crest produce a bent tube 2.7 $\mathrm{m}$ long. What is the fundamental frequency of this tube, assuming the bend has no effect on the frequency? (For comparison, a typical human hearing range is 20 $\mathrm{Hz}$ to 20 $\mathrm{kHz.}$ $$ \quad \text { A. } 0.0039 \text { Hz } \quad \text { B. } 32 \mathrm{Hz} \quad \text { C. } 64 \mathrm{Hz} \quad \text { D. } 130 \mathrm{Hz} $$

Transcript

00:01 In 109, we're told that a certain dinosaur has a frequency, well, makes a frequency sound of 74 hertz, and we're asked to find how long the air column is in the crest.

00:14 Remember, that's a thing that sticks out to dinosaur's head that acts like an open resonating tube.

00:21 We know that there's half a wavelength in here, so a wavelength would be two times this length.

00:29 We would need two times this length to get a whole wave...
