Why is it louder the faster the speed?

1. Sound is produced by friction, the slower the speed, the friction.

Conversely, the faster the speed, the greater the friction and the louder the sound.

2. The speed is fast and a large amount of heat energy will be rapidly generated, which will make the surrounding tissues heat and expand, which will increase the friction, so the faster the pumping, the louder the sound.

3. When an object is tangent along the contact surface with another object.

Directional motion or relative motion.

There is a force between the contact surfaces of two objects that hinders their relative motion, and this force is called friction.

4. This phenomenon or characteristic between the contact surfaces is called "friction". Friction is both good and bad, but in most cases it is bad.

5. For example, car engines.

is a producer of the biggest noise, because the gasoline is burning in it, like a firecracker, it will definitely make a loud noise.

6. The sound of mechanical friction and knocking, such as the sound of valves, the sound of pulleys and belts, and the crankshaft.

and the sound of pistons running.

7. Intake noise, the air passes through a long intake pipeline and passes through the air filter.

When entering the engine, it is also quite noisy because of the high airflow speed.

Hello, check the tire bearing, and whether the tire is deformed, generally these two reasons. Speed is mostly related to bearings.

Summary. Hello, dear. The faster you go, the louder you scream, because the faster you are, the faster your voice vibrates, the higher the frequency of your voice, and the higher the pitch.

The slower the speed, the smaller the friction, so the sound is smaller, and conversely, the faster the speed, the greater the friction, and the louder the sound.

Hello, dear. The faster you go, the louder you scream, because the faster you are, the faster your voice vibrates, the higher the frequency of your voice, and the higher the pitch. The sound is produced by friction, the slower the speed, the smaller the friction force, so the sound is smaller, on the contrary, the faster the speed, the more scattered the friction force, and the louder the sound is made.

Extended information: The fast speed will also rapidly produce a large amount of heat energy such as clump pins, which will make the surrounding tissues expand by heat and increase the friction force, so the faster the pumping, the louder the sound. When an object and another object move along the tangential direction of the contact surface or have a tendency to move relative to the slag swim, there is a force between the contact surfaces of the two objects that hinders their relative motion, and this force is called frictional Zheng impulsive force.

Question "Why is the sound so fast?" It's a bit confusing because it implies that the sound is faster than expected, but in reality, the speed of the sound is a fundamental property of the physical world. Here is a summary of the details:

Sound is a mechanical wave that travels through a medium, such as air or water. When sound is generated, it creates a perturbation in the medium and propagates outward in the form of waves.

The speed of sound depends on the properties of its propagating medium, such as density, temperature, and elasticity. In general, coarse sound propagates faster in denser, hotter, and more elastic materials.

In dry air at sea level, the speed of sound is about 343 meters per second, or about 1,235 kilometers per hour (767 miles per hour). This speed can vary depending on factors such as altitude, humidity, and air pressure.

While the speed of sound may seem fast, it is actually comparatively slower compared to other types of waves, such as electromagnetic waves (including radio shouting waves, light waves, and X-rays) that travel at the speed of light, i.e., about 299,792 kilometers per second.

The speed of sound is important in many areas, such as acoustics, acoustics, and engineering. It also has practical applications, such as medical imaging techniques such as ultrasound and the design of supersonic aircraft.

In summary, the speed of sound is a fundamental property of the physical world, it depends on the properties of the medium it passes through, and while it appears to be fast, it is actually relatively slow compared to other types of waves.

Medium is required for sound propagation, and the higher the density of the medium, the faster it travels, because the density of the solid is the largest, so the sound travels faster in the solid than in the liquid body.

The propagation of sound in a medium depends on the collision of particles in the medium, and the faster the speed is when the direction of the collision is more likely to coincide with the direction of sound wave propagation.

In gaseous liquid solids, these particles are usually molecules or atoms (collectively referred to as molecules for convenience). The most basic difference between the three states of matter of gas, liquid, and solid is the average free path of the molecule.

Or the degree of restraint is different, or it can be said that the average spacing is different. The free path of the irregular movement of the molecules in the gas is large, that is, the distance traveled before the next collision is long, that is, the waiting time for the next collision is long, so that the mechanical waves.

Naturally, it takes longer to spread. The average free path of liquids is much smaller, the molecules are only fixed in a small area for vibration, and the time required for the next collision is shorter, so that the mechanical wave propagates faster and infiltrates. Solids have a smaller average free path than liquids, so they propagate faster.

So from a macroscopic point of view, in general, in terms of density, solid, liquid, and gas, so this situation will occur. But it is not absolute, so the speed of sound is distinguished by density.

Not quite right, such as water and ice. But ice is known to be less dense than water.

After experiments, we already know that temperature also contributes greatly to the propagation of the speed of sound, and generally the temperature of the same medium increases with the speed of sound, of course, this can be explained by the increase in temperature and the acceleration of molecular vibration. In addition, there is the problem of materials, shape, doping, etc., which can change the speed of sound propagation.

Therefore, the speed of sound propagation has a lot to do with the interaction between the molecules in the medium, if the interaction of the molecules in the medium is very strong, then the speed of propagation is relatively fast, on the contrary, if it is weaker, even if the density is relatively large, the speed of sound propagation will not be very high. (e.g. iron and lead).

Hello, "Because the faster the speed, the faster the voice slides and vibrates, the higher the frequency of your voice, and the higher the key." The speed is fast, and a large amount of heat energy is rapidly generated, which makes the surrounding tissues expand by heat and increase the friction force, so the faster the ridge is pumped, the louder the sound. For example, the car engine is the biggest noise producer, because the gasoline is burning inside, just like a firecracker, it will definitely make a loud noise.

The slower the speed, the smaller the friction, so the sound is smaller, on the contrary, the faster the speed, the greater the friction, and the louder the sound. We hope we can help you <>
