Why does a balloon make a loud sound when it bursts?

Listen to me explain. My science.

When the balloon grows larger, the pressure inside and outside is always the same The analysis shows that the sum of the pressure of the external atmosphere and the pressure generated by the elastic force of the balloon skin on the internal gas is equal to the pressure of the internal gas on the ball skin, that is.

p (external atmospheric pressure) p (pressure generated by the elastic force of the balloon) p (internal gas pressure) When there is a hole in the skin of the balloon (a matter of a moment), the pressure difference between the two sides of the hole is large (as can be seen from the above formula), so the internal gas gushes out sharply, and the ball skin will be torn apart instantly

You can think about it, bombs, tires, etc., their ** is also because of the sharp vapor vibration Like a bomb, for example, he relies on the chemicals in it to instantly react and release a large amount of heat, which will make the surrounding gas expand sharply, killing and injuring the enemy In the process, there is a big vibration of the gas, resulting in a loud noise So, the essence of sound is vibration.

When it is broken, the outside vapor will flow into the space occupied by the original ball, and at this time, the vapor will flow rapidly, it will vibrate, and it will make a sound, of course, the ball will also make a sound, because it is also moving, hehe.

The air pressure inside the balloon increases, causing the balloon to burst, causing strong air vibrations. The sound is produced.

Why do balloons get bigger? Because people forcibly put air pressure into the balloon, the requested internal atmospheric pressure is stronger than the outside. When there is a hole in the skin of the balloon, the gas inside it is forced to pass through the hole in an instant under atmospheric pressure, and the balloon is naturally burst by the gas.

Because the balloon is bursting, the epidermis vibrates violently at the same time, and it makes a loud sound.

The sound is caused by the vibration of the object, when the balloon bursts, the air in it rushes out of it (the pressure is stronger than the outside, equivalent to a shock wave), causing the surrounding gas to vibrate and produce a loud noise, but the balloon itself does not make too much noise.

Find a balloon, blow it up and tie it tightly with a thin thread and prick it with a needle, the balloon ** makes a loud noise, because the hole of the needle is small, the air in the balloon comes out of such a small hole, and the air vibrates violently, so the balloon ** makes a loud noise.

The noise of the airplane sounds short and light on a sunny day, and it sounds long and deep on a cloudy day, because the temperature of the air on a cloudy day is not as high as that on a sunny day, and the speed of sound propagation is related to the size of the air temperature.

The ** sound when the balloon bursts is made by air vibration x0d Find a balloon, blow it up and tie it tightly with a thin wire with a needle, the balloon ** makes a loud noise, because the hole of the needle is small, the air in the balloon comes out of such a small hole, and the air vibrates very violently, so the balloon ** makes a loud noise The noise of the x0d aircraft sounds short and light on a sunny day, and it sounds long and deep on a cloudy day, because the temperature of the air on a cloudy day is not as high as that on a sunny day, and the speed of sound propagation is related to the temperature of the air. Sunny days are fast, cloudy days are slow.

Standard physical atmospheric pressure.

It is Pascal, the air in the balloon is blown in or pressed in with a pump, that is, the balloon is filled with compressed gas, and the pressure inside the balloon is higher than the atmospheric pressure outside.

When the sphere is squeezed, the volume decreases and the air pressure increases, and when the temperature rises, the volume does not change, and the air pressure increases).

When the pressure of the balloon is reached, the film on the surface of the ball will burst, and the volume of compressed gas in the ball will suddenly expand rapidly, causing the surrounding air to vibrate sharply, so it makes a "pop" sound.

There are many similar vocalizations and phenomena.

Such as gas cylinders**, tires**.

Because this is because the density of air inside the balloon is greater than the density of air outside the balloon, so due to the principle of air diffusion, the air in the balloon will spread outward, plus the pressure in the balloon, the air will go out faster. As a result of this, the hole of the balloon was burst due to the fact that it could not stand such pressure, causing a vibration of the air, which produced a sound.

I cause a sharp vibration of the surrounding air, so I make a snapping sound! This statement is certainly inaccurate, the snapping sound is not entirely caused by the sharp vibration of the air, and it can even be said that the vibration caused by the gas is very small, and it will not make a snapping sound, which is the sound caused by the ** of the balloon. Why?

For example, take the gas used at home! When we open the gas valve, we don't hear the sound of popping at all, we can only hear the sound of the gas going out under pressure, the sound of Ziz.

If it's a gas cylinder, there must be a sound.

The air pressure inside the balloon is higher than that outside, and when it bursts, the high-pressure gas acts on the outside gas to produce a strong pressure wave.

That is, the air oscillates, and this oscillation is transmitted to the person's eardrum, on.

Hearing. Bang".

Sound is the response of the eardrum to the intensity of air waves.

The sound of skin vibrations?

If you stretch the balloon and pluck it hard, will it make a similar strong sound? ~~

The internal air pressure of the expansion balloon is much higher than the outside atmospheric pressure, so when it bursts, it causes the air to expand sharply, and in nearly a thousandth of a second, the original internal gas of the balloon collides strongly with the surrounding air molecules, producing a huge shock wave (the frequency of the shock wave is very high, beyond the limit of human hearing).

In the process of propagation, the energy is quickly decayed, and its wavelength gradually increases, until it finally evolves into "sound waves", which enter the hearing range of the human ear, so we hear the "pop" of the balloon.

Listen to me explain.

First, consider how sound is produced: sound is emitted by the vibration of an object and travels through a medium.

Secondly, consider whether there is vibration: when the balloon **, the volume of the gas in the ball suddenly expands, and the gas vibrates violently, so it makes a sound.

Secondly, after the balloon**, the vibration generated by the gas quickly disappears, and the sound also disappears quickly.

The balloon**, which makes a sound, is produced by the violent expansion and vibration of the air.

Sound is mechanical vibration, and the propagation of sound waves in the air is a transmission of vibration.

The reason why the balloon is inflated is that the internal gas pressure is greater than the sum of the atmospheric pressure and the elastic force of the balloon, and when the inner and outer balances are reached, the balloon will not inflate again. When the balloon bursts, the internal air pressure is not bound by the elastic force of the balloon, it is greater than the external atmospheric pressure, so it expands rapidly, which is a bit similar to **, the rapidly expanding gas causes violent air vibration and produces sound waves, so it will make a sound.

The internal air pressure of the expansion balloon is much higher than the outside atmospheric pressure, so when it bursts, it causes the air to expand sharply, and in nearly a thousandth of a second, the original internal gas of the balloon collides strongly with the surrounding air molecules, producing a huge shock wave (the frequency of the shock wave is very high, beyond the limit of human hearing).
