Can sound only travel through the air?

Sound doesn't just travel through the air. The propagation of sound requires a medium, air is only one of the mediums, and sound can propagate in gases, liquids, and solids, among which the propagation speed in solids is the fastest.

Sound can also travel in water, solids, liquids, and it travels faster in it.

Sound is a kind of wave, there is a certain wavelength frequency and energy, the wave encounters matter in the process of transmission, such as the empty situation you said, the sound wave meets the air and then diffuse reflection, diffraction, etc., the energy is attenuated, when the sound wave energy attenuates to a certain extent, the wavelength of the sound wave, the frequency range is beyond the acceptable range of our hearing, we can't hear. However, depending on the direction in which the sound wave is emitted, the energy transferred and the speed of energy decay will also be different, so the sound volume heard in different places will be different. If there were no obstacles, that is, if the energy was not decayed, the sound waves would continue to propagate, which is ideal, but in fact it does not exist.

No, all solids, liquids, and gases can transmit sound.

Sound is a wave generated by the vibration of an object, which is a wave phenomenon that propagates through a medium and can be perceived by the auditory organs of humans or animals.

The statement that sound can only travel through the air is false. Actually air can travel in any medium, but the speed of propagation is different, and the speed of propagation in different media is not the same.

No. Sound can travel in gases, liquids, solids.

No, it can also spread in water, in solids.

There are the following examples of how sound can travel through the air:1. Singing in the classroom, which can be heard outside the classroom.

2. The sound of car and train horns comes to our ears.

3. The village horn sounded, and we could all hear it.

Acoustic propagation is transmitted through a medium. Due to the vibration of the object, sound can be produced, and sound is the fluctuation caused by the vibration of the spine of the substance, which needs to be transmitted by the medium to be heard.

The speed at which sound waves are transmitted in a medium is called the speed of sound (or speed of sound), and the reflection and refraction of sound occurs due to the different speeds at which sound travels in different media. Sound is produced due to the vibration of objects, and sound is a fluctuation caused by the vibration of matter, which needs to be transmitted by the mediator to be heard.

In the 18th century, scientists experimentally confirmed the idea that sound waves need air and other permeable substances to transmit them. About 1,700 years ago, the Italian scientist Torricelli proposed the idea that sound is transmitted through air.

Sound travels in the air as sound waves, and in solids and liquids it also travels as sound waves, but at different speeds. In the air, the propagation of sound is manifested by the oscillation of the air molecules by the sound source, resulting in a certain dense distribution, and this dense distribution is transmitted through the interaction between molecules.

Sound travels through the air in the form of sonic friendliness. The propagation of vibrations produced by the emitter in the air or other substances is called a sound wave. Sound waves travel in all directions with the help of various mediums.

Sound waves are usually longitudinal waves, but also transverse waves, and the propagation of sound waves is essentially the transfer of energy in a medium.

Sound waves can be understood as the propagation of small perturbations of a medium that deviates from the equilibrium state. This propagation process is only the transfer of energy and does not take place the transfer of mass. If the perturbation is relatively small, the propagation of the sound wave satisfies the classical wave equation and is a linear wave.

If the disturbance is large, the linear acoustic wave equation is not satisfied, and the dispersion of the wave and the generation of shock waves will occur.

The propagation of sound requires a medium, which can propagate in solids, liquids, gases, but not in a vacuum

So the answer is: vacuum

Sound cannot travel in a vacuum. Sound wave is a mechanical wave that requires a medium to propagate, and there is no medium present in a vacuum, so it cannot propagate.

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. An object that initially emits vibrations (vibrations) is called a sound source.

Sound travels in the form of waves that vibrate (vibrate). Sound is the motion formed by the propagation of sound waves through any medium. Sound is a wave.

Sounds that can be recognized by the human ear (frequencies between 20 Hz and 20000 Hz) are called sounds.

The three attributes of sound are: loudness, pitch, and timbre.

1. Determinants of loudness: the strength of the sound. Loudness is related to the amplitude of the object, and the greater the amplitude, the greater the loudness; The lower the amplitude, the less loudness. Loudness is also related to the distance from the emitter.

2. Application of loudness: The physical quantity to describe the size of the sound is decibels, and the symbol is db. Generally, noise levels higher than 50db will have harmful effects on human daily work and life, such as hearing damage, heart and blood vessel damage, etc.

3. The determinant of tone: the height of the voice. The pitch is determined by how fast the object vibrates (in physics, frequency is used to represent how fast or slow an object vibrates), the higher the frequency of the object, the higher the pitch, and the smaller the frequency, the lower the pitch. Talk about the feast.
