Is there a sound in the world that can make a sound without vibrating?

No, you can see the basic principle of vocalization.

Sound is produced by vibrations transmitted through the air (vibrations) to the eardrum to the human nervous system, so in a vacuum, sound cannot be transmitted. Of course, people with a bad nervous system and ruptured eardrums (deafness) can't hear sounds, hehe.

Sound is produced by the vibration of an object, and the object that is emitting sound is called the sound source.

Sound is simply the movement of pressure waves through the air. Pressure waves vibrate the small bones of the inner ear, and these vibrations are converted into tiny electronic brain waves, which are the sounds we perceive. The inner ear works on the same principle as a microphone captures sound waves or a speaker's articulation, which is the relationship between a moving mechanical part and air pressure waves.

Naturally, when the sound wave is pitched low, moving slowly, and loud enough, we can actually "feel" the air pressure wave vibrating the body. So we perceive sound with the mixed parts of the body.

The elements of sound production are, first, the sound source, and all sound emitters are vibrating, vibration stops, and sound also stops; Second, there must be a medium, and the vacuum cannot transmit sound; The third is that the human auditory system is normal.

If any of the above points are missing, no one can hear the sound.

No, because sound is perceived by the medium transmitted to the eardrum after the object vibrates, how can the object vibrate and how to perceive the eardrum if it does not vibrate?

No, because the essence of sound is vibration.

Isn't the voice of the heart not a sound?

Does the title mean that there is no vibration?

I'll give you an empty bowl to intercede, you eat noodles, forget it!

No, you should take a good look at the definition.

Sound is produced by the vibration of an object.

No, because objects make sounds by vibrating.

Sound waves are mechanical waves that need to be propagated by the vibration of the particles.

The shaking happens. Vibration of the body occurs.

The correct way to put it is: everything that is making sound vibrates, because it is impossible to make sound without vibrating. It is wrong for the vibration to make a sound because the alarm clock in a vacuum, although it vibrates, does not make a sound.

But vocalizations don't have to vibrate, because vocalizations must vibrate. Sounds may not be audible, such as ultrasound.

Sound is a sound wave produced by the vibration of an object. It is a wave phenomenon that propagates through a medium (air or solid, liquid) and can be perceived by the auditory organs of humans or animals. Sound travels in the form of waves that vibrate (vibrate).

Sound is the motion formed by the propagation of sound waves through any substance. Sound is a wave, and the sound with a frequency between 20 Hz and 20 kHz can be recognized by the human ear.

The vibrations must sound, but you can't hear them. Because the definition of sound: sound itself is the vibration of an object.

As for the absence of air, vacuum, it just does not transmit sound, that is, it does not transmit vibration.

I hope it will be useful to you and I wish you a speedy resolution of this issue.

Viewpoint 1: Sound in the narrow sense refers to the vibrations of air that can be felt by the human ear. What is actually felt is a change in air pressure that is due to the vibration of the emitter.

Generalized sound waves are not limited to human perception. Acoustic waves can be defined as: the position, density, and pressure of the mass elements of an elastic medium (solid, liquid, gas), and the disturbance that occurs with respect to the rest value.

For example, elastic waves in solids, also known as stress waves, fall into the category of generalized sound waves.

In layman's terms, all vibrations are sounded, and it is only a matter of whether people can hear them.

Viewpoint 2: Sound requires mechanical vibration, but mechanical vibration does not necessarily mean sound, and where there is no medium, sound waves (mechanical waves) will not propagate, so there will be no sound. Vibration is only a necessary condition for vocalization, but not a sufficient condition.

I can't figure it out when I hear you, I looked it up on the Internet, and there are roughly the above two points of view, please help the netizens downstairs solve it, let me figure out this problem too, please help everyone.

The object that makes the sound must vibrate, and the object that vibrates does not necessarily make a sound.

There are two basic conditions for sound to reach the human ear and be perceived. First, there is a sound source; Second, there is a medium of transmission.

However, for the sound emitted by a vibrating object to be perceived, there must be a medium of propagation to transmit the sound. If you see an object making a sound in a vacuum, you can't hear the sound because there is no medium to transmit the sound to your ears, and the so-called vibrating object doesn't necessarily make a sound.

The vibrating object must be making a sound – right, but when the vibration frequency is less than 20 Hz or more than 20,000 Hz, the human ear cannot hear it.

Because there are audible sounds (20 20000Hz), infrasound (less than 20Hz) and ultrasound (more than 20000Hz).

Your understanding of the definition of sound is wrong, a little vibration may not be heard, whether you can hear it or not is determined by the factors of propagation and frequency.

In a vacuum, the celestial body ** is that you can't hear the sound because it can't be transmitted, if you can put your ears to listen to the sound, you can hear it, this is the second year of junior high school physics, go back to junior high school to make up for your lessons.

Both vibration and sound waves are essentially a type of wave.

The machine makes a sound when it is running, and if you touch the housing of the machine with your hands, you will feel the housing vibrating. If the power supply is cut off, the sound will disappear when the shell stops vibrating, indicating that the vibration of the object produces sound. Generally, the object that vibrates and emits sound is referred to as the sound source.

The sound source can be solid, such as various machines; It can also be liquids and gases, such as the sound of running water is the result of liquid vibration, and the sound of wind is the result of gas vibration. Not all vibrations of objects can be heard by the human ear, only the sound produced by the vibration frequency in the range of 20-20000Hz can be heard by the human ear. Vibrations in this frequency range are called acoustic vibrations, and acoustic vibrations are mechanical vibrations.

The energy emitted by the vibration of an object is only transmitted to a receiver (such as a person) through the medium, and the displayed sound is the sound. Therefore, the formation of sound is composed of two links: the occurrence of vibration and the propagation of vibration. There is no sound without vibration, and similarly, there is no medium to propagate vibrations, and there is no sound.

As an intermediate medium for the propagation of sound, it must be a substance with inertia and elasticity, because only the medium itself has inertia and elasticity to continuously transmit the vibration of the sound source. Air is such a medium, and most of the sounds that the human ear usually hears are also transmitted through the air leakage of empty pants. The medium through which sound is transmitted can be gases, liquids and solids.

Sounds that travel through the air are called airborne sounds, sounds that travel through water are called water sounds, and sounds that travel in solids are called solid sounds (or structure-borne sounds). When sound propagates in a medium, the particles of the medium themselves do not pass with the sound, but the particles vibrate back and forth near their equilibrium positions, and it is the energy of the movement of the matter that travels out, not the matter itself. The essence of sound is a form of motion of matter, and this form of motion is called fluctuation.

For this reason, sound is also known as sound waves. Sound waves are alternating pressure waves, which belong to mechanical waves.

Sound is the vibration of air particles, and sound cannot travel in a vacuum, just look at it from a microscopic physical image.

If you don't shake, you won't work.

The definition of "sound" is the sound wave produced by the vibration of an object due to the vibration of the air around it, but what is commonly referred to as "sound" refers to something that a person hears. Sound waves must be received by human sensory organs, such as ears, so that they can "hear" and "sound". If the ears are blocked, even if someone beats the drum in front of them, the sound waves generated cannot be received, and the person cannot hear the "sound", but the sound waves are still there.

In other words, vibrations are "silent" and you can hear "sound" because the ear can hear them. Vibrations that are outside the range of frequencies received by the human ear cannot be received by the human ear, which means that these vibrations are "silent" to the person.

Sound vibrating vocalization? The question itself is contradictory, right? The vibration of an object produces sound waves, which are transmitted to the human ear through a medium, and then we hear the sound. Of course, sound waves have a specific frequency to be heard, low sound waves, noisy sound waves we can't hear.

Sound vibrations can create waves.

Sound is produced due to two or more things vibrating at different frequencies.

The essence of sound is the vibration of the air current, and the range of sound that people can hear is 20-20000Hz, that is, the air vibration under 20-20000 vibrations per second can be heard by the human ear.

The object should make a sound, and the vibration frequency should also be within this range, the object vibrates, driving the air to vibrate, and the air vibration is transmitted to the eardrum, causing the eardrum to vibrate, and then it is accepted by the human ear.

I hope it helps you, if you have any questions, please ask o( o haha

Because the propagation of sound is carried out by the vibration of the air, etc., the vibration of an object causes the surrounding air to vibrate, so we hear sound.

To put it simply, the main reasons are: the earth's various large slabs are squeezing each other. It was also caused by volcanic eruptions.

**Divided into natural** and artificial**.

Kind. Naturally**mainly tectonic**, it is due to the rupture and dislocation of rocks deep underground that release the energy accumulated for a long time sharply, and propagate in all directions in the form of **waves, causing the house to shake the ground caused by the ground. Structures account for more than 90% of the total.

This is followed by volcanic eruptions, called volcanoes, which account for about 7% of the total. In addition, Wang Song will also produce ** under some special circumstances, such as cave collapse (collapse**), large meteorite impact on the ground (meteorite impact**), etc.

Artificial is caused by human activity. Such as vibration caused by industrial blasting and underground nuclear **; High-pressure water injection in deep wells and the impoundment of large reservoirs increase the pressure in the earth's crust and sometimes induce it.

The place where the wave originates is called the hypocenter. The vertical projection of the hypocenter on the ground is called the lead epicenter. The depth from the epicenter to the hypocenter is called the hypocenter depth.

Usually the depth of the epicenter is less than 70 kilometers is called the shallow source**, the depth of 70-300 kilometers is called the middle source**, and the depth is greater than 300 kilometers is called the deep source**. Destructive** is generally a shallow source**. For example, in 1976, the depth of the epicenter of Tangshan** was 12 kilometers.

Thermal convection of mantle material. It is driven by the energy produced by the decay of radioactive elements in the Earth's interior. It is the external manifestation of the release of energy from within the Earth.

Internal energy release takes the following forms: volcanoes, plate movements, and geological formations. ** is one of them.

1 There is an epicenter inside the earth, and the epicenter releases energy (** waves) outward, causing vibrations within a certain range

2. Other geological disasters or natural disasters can also be indirectly induced**
