Is the sound going up or down, and is the sound going up?

Sound can travel upwards or downwards.

Sound is the movement formed by the propagation of sound waves through any medium, gases, the speed of propagation of sound is related to the type of medium and the temperature of the medium. Sound is a sound wave produced by the vibration of an object. It is a wave phenomenon that is transmitted through a medium and can be perceived by the auditory organs of humans or animals.

Sound travels upward, but not just upward; Sound can travel in all directions. Because sound travels through a medium, sound can be transmitted in a specific way.

Both animals and humans transmit sound through their vocal cords, and with sound we can communicate and reproduce. So, is the sound going up or down?

01 In general, it should be common sense that sound is transmitted by the vibration of the air. The same is true for other media. That is, the source of vibration first causes the nearby air to vibrate, and this air vibration will propagate to the surrounding area.

The frequency and intensity of this air vibration is within a certain range, and we can hear it.

02 The essence of air vibration is that part of the air is continuously compressed by the source, and the elasticity of the compressed air will expand outward layer by layer, forming the so-called sound wave. Humans can hear sounds within 20 hertz to 20,000 hertz, below 20 hertz or above 20,000 hertz, which belong to infrasound and ultrasound, and we humans can't hear it. But some animals can be heard.

03 Sound waves have energy, and energy will be consumed and attenuated in the process of propagation. It can also be scattered or absorbed by other objects. So in the ** hall or recording studio, we often see walls decorated with materials that absorb sound waves.

It is to prevent excessive reflection of sound from forming noise.

04 In nature, the sounds produced by the earth, such as the sound of wind, thunder, waves, etc., will gradually attenuate in the process of propagation. When these sounds decay below 40 decibels, creating a background sound, we feel that the environment is quiet. Eventually, the sound produced on Earth will disappear completely due to attenuation.

05 Sound can also travel in solids or liquids, and it will travel a little faster. Because the principle is similar to airborne, I won't repeat it.

Sound can travel upwards or downwards.

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.

The propagation speed of sound in different media is generally solid, liquid and gas, and the propagation speed of sound is related to the type of medium and the temperature of the medium.

Sound travels upward, but not just upward; The sound travels in all directions. Sound is transmitted through a medium. But the sound can be directed in a specific way.

The sound waves that travel through the air are longitudinal waves, and the constantly vibrating tuning fork causes the surrounding air molecules to form a continuous density pattern. In longitudinal waves, the vibrating force of the molecules of the medium is parallel to the direction of the wave.

The propagation velocity of sound in different media in the sound source is generally solid liquid gas (exception: 100: cork 500m s, less than kerosene (25), distilled water (25), etc.), propagation speed, medium type, medium temperature.

Sound always contains a certain range of frequencies. The frequencies of sound that can be heard by the human ear are between 20 and 20 kilohertz.

Waves beyond this range are called ultrasound, and waves below this range are called infrasound. Animals like dogs and bats can hear sounds up to 160,000 hertz. Whales and elephants make sounds with frequencies between 15 and 35 Hz.

Sound is a pure wave, not a substance in itself, and cannot be transmitted without matter. The speed at which sound travels has nothing to do with the direction, only with the substance that travels it. For example, in the air, the propagation speed in hot air is fast, and the propagation speed in cold air is slow.

Sound is a type of energy, and if a sound encounters a black hole, if the sound is sucked in. The sound also has weight, as if a black hole can suck it in, but you can't suck the sound into it, and there should be no sound if it has weight.

When vibrations produce waves, they make sounds. Sound has no weight, but the medium of propagation does. For example, in the speech of air, the air has weight, in the speech of water, the water has weight, but the sound itself has no weight.

The velocity of sound is in the same medium and is theoretically direction-independent. However, the medium itself has weight, so in the environment of gravity, the speed of sound that deviates from the direction of gravity is a little slower, that is, on the earth, the upward speed of sound is slightly slower.

Is it loud that the sound travels upwards or loudly downwards? I think generally the sound travels upwards, because when you shout, the voice rushes upwards with the qi. So I think still. The voice spread online is loud.
