In terms of the nature of sound, sound is also sound waves, which are produced by the vibration of objects. The propagation of sound is actually the propagation of vibrations, so it must rely on the medium, which can be gases, liquids and solids. Sound has a certain range of vibrational frequencies below which it cannot be heard, and above it cannot be heard.
Since sound is vibration, there must be energy in the sound, which has nothing to do with the information. Just like the sound of thunder, whether you hear it or not, it contains energy.
Regarding information, I think that whether it is unconscious or conscious material transmission, it is possible that information, such as thunder, is formed unconsciously, but we hear thunder and get information that lightning is happening. There is also human language, if you understand it, you will get information, and if you can't understand it, it is not information or useless information. There are many carriers of information, such as photoacoustics and electricity, and for computers, binary ** may be its information.
So, there is no direct relationship between the energy and the message of sound.
The question is, and does light transmit energy or information? This question is the same. There must be energy, but not necessarily information, and there is no direct relationship between the two.
Or it can be argued that there is a change in energy when there is a spread of information, but a change in energy does not necessarily lead to the spread of information.

Sound can transmit information as well as energy.
The key is whether the sound can change the shape or state of the object.
For example, if the body is examined, then the various parts of the body will not change, but only reflect the health status of the body, which is the transmission of information.
If you break up a stone, you break a large stone into small pieces, and the shape changes, which is the transfer of energy.
Specific problems are analyzed on a case-by-case basis.

From the point of view of physics, it transmits energy (the horn can shatter the glass), and from the point of view of informatics, the transmission of sound waves has certain laws and characteristics, and can carry information (wolves use howls to find mates).

Sound is a wave produced by the vibration of an object, and it requires a medium to propagate. Vacuum cannot transmit sound. We usually speak with air as a medium, and solids transmit sound faster than any other form.
The process by which we hear sound is roughly as follows: Vibrations of the body - propagation through the medium - Vibration of the eardrum - Osstaltic bone tissue - Auditory nerve. Some people who are deaf (eg; Beethoven) was also able to feel sound, using the principle of bone sound transmission.
Humans also use sound waves to transmit information and energy. For example, echolocation, sailing on the sea, the crew can measure the depth of the seabed by radiating sound waves to the seabed, and after a certain period of time, the sound waves touch the seabed and then come back. There are also in the medical aspect, etc.
-
The question is changed to why sound waves can transmit energy more appropriately, because sound is the perception of vibrations by the human ear.
Sound waves are mechanical waves, and in the process of mechanical wave propagation, the particles in the medium that were originally relatively stationary vibrate with the propagation of mechanical waves, which indicates that these particles have gained energy, and this energy is transmitted from the wave source through the previous particles in turn. Therefore, the essence of mechanical wave propagation is the propagation of energy, which can be small or large, and the tidal energy of the ocean can even be used to generate electricity, which is the energy that maintains the propagation of mechanical waves (water waves) is converted into electrical energy.

The sound is a wave, you want to float a stick on the water, if you throw a stone near the stick, the ripples will make the stick jump up and down, isn't this the energy of the stone transmitted?
-
Sound transmission information refers to what information content can be told by sound, for example: the teacher gives a lecture on the podium so that the students gain knowledge, this knowledge is the information transmitted by the voice, and the teacher makes the white paper bulge when he speaks, indicating that the sound can transmit energy.

Ultrasonic** is the best proof of this, followed by ultrasonic cleaning.
It's no longer a new topic.
To prove that sound waves transmit energy, you can try the following experiments:
You can find a tablet, put it directly above the speaker (the speaker is flat), and then put some small particles on this plate, such as foam crushed, rice grains, etc. (to be light), and then ****, you will observe that these small particles are beating, **What about the energy? Of course, it's the sound wave that comes from the pull!
Of course, there are many more experiments that can prove this fact, and you can imagine a thunderstorm happening around you.
Sometimes the sound of thunder will shake the glass with a bang, which is of course the energy of the sound waves.
Of course, the magnitude of the energy transmitted by the sound wave and the frequency and loudness of the sound source.
All have a certain relationship.

In a short period of time, the two people see the same because the organs have not changed (such as vision and color sense), but the perception of seeing things is different, and the more special (unexpected) the things seen, the more different the sensations will be. The more time passes, the more different your views become. It is not possible to sense each other, but it will often go to the same place, encounter similar things, and respond similarly; In the same way, you can't hold each other back, you can't participate in the control of two of your own autonomous actions at the same time, and in general, the two people are independent individuals. >>>More
Galileo In ancient times, although some philosophers of ancient Greece, such as Plato, had assumed that air had weight, they could not weigh it, so people always believed that air had no weight. In the 17th century, the great scientist Galileo Galilei conducted experiments and proved that air has weight. >>>More

Sound is a kind of signal, from the level of the signal, you can decompose any sound into a variety of different frequency sounds, for example, the sound of dolphins, the frequency is very high, the whistle of a ship, the frequency is very low, human beings can listen to the sound from 20hz to 20000hz, when we usually listen to a singer singing, what we hear is the synthesis of these sounds in these frequency ranges from his throat, the voice is clean, for example, a tenor singer, The approximate frequency of the sound emitted is 1000hz plus or minus no more than 50hz, (of course, the data is made up by me,,I don't understand),Unclean sound,The frequency range covered is relatively large,For example, from 100hz to 1000hzThere are some,It's just that the intensity near a certain frequency is larger。 >>>More
