Short Answer

What is the evidence that sound is a form of energy?

Following are the point which shows that sound is in the form of energy.

As sound is a form of energy, therefore it performs work.
Because of sound, there is mechanical vibration.

Step by Step Solution

TABLE OF CONTENTS

Write the characteristics of energy

Consider the following characteristics of energy:

Any type of energy can be used to do work.
Energy may cause mechanical vibration.

Check the characteristic of sound

The following points can be observed for sound relative to energy:

Sound does work; therefore, it is a form of energy.
Sound does cause mechanical vibration.
For example, sound can set eardrums in motion, and a large sound level may cause rattling of the window, and sound can break the glass.

Thus, the sound is a form of energy.

A noisy truck approaches you from behind a building. Initially you hear it but cannot see it. When it emerges and you do see it, its sound is suddenly “brighter”—you hear more of the high-frequency noise. Explain. [Hint: See Section 11–14 on diffraction.]

Question: (II) What would be the sound level (in dB) of a sound wave in air that corresponds to a displacement amplitude of vibrating air molecules of 0.13 mm at 440 Hz?

What is the intensity of a sound at the pain level of 120 dB? Compare it to that of a whisper at 20 dB.

(II) The two sources of sound in Fig. 12–16 face each other and emit sounds of equal amplitude and equal frequency (305 Hz) but 180° out of phase. For what minimum separation of the two speakers will there be some point at which (a) complete constructive interference occurs and (b) complete destructive interference occurs. (Assume T = 20°C.)

Question: Manufacturers typically offer a particular guitar string in a choice of diameters so that players can tune their instruments with a preferred string tension. For example, a nylon high-E string is available in a low- and high-tension model with diameter 0.699 mm and 0.724 mm, respectively. Assuming the density \(\rho \) of nylon is the same for each model, compare (as a ratio) the tension in a tuned high-and-low tension string.
