Why is there a squeezing sound in the beehive?

There are many reasons, one is that the weather is hot, and the bees are flapping their wings to cool down. Second, it is possible that people or other small animals have alarmed the bee colony, and the bee colony makes noise. The third is that the bees will make a snorting sound when they are separated or fleeing from the bees.

The buzzing of bees comes from the vibration of their wings, up to 200 times per second, and if the wings stop vibrating, the sound also stops.

When the bee is flying, the frequency of the vibration of the flapping wings is very fast, forming a high-speed resonance with the surrounding air, and this shock wave reaches our ears, and we hear a "buzzing" sound. In the same way, we can hear the buzzing of flies.

Because there is a small black dot at the root of the bee, the small black dot agitates up and down when the wings are flapped.

1. The buzzing sound of bees is mainly the sound produced by the eardrum under the wings.

2. Although the wings of the early bee are flapped 200 times per second, the buzzing sound is not because of the sound of the wings flapping, but the small black dots under the wings, which are called the generators of the eardrum.

3. Through the test, even if the bee's wings are cut off or glued with super glue, the bee can still make a buzzing sound. If you puncture the eardrum of a bee with a needle, the bee will no longer be able to buzz.

This experiment tells us that people used to think that the humming sound produced by the flapping of the wings of bees was wrong, and that the real vocalizations of bees are the eardrums under the wings.

Bees make what they hear by vibrating their wings to make what everyone hears as "buzzing".

An 11-year-old girl went to the apiary to play and noticed a strange phenomenon: the bees gathered on the beehive, buzzing non-stop, but not flapping their wings. She remembered that the textbook said that the buzzing of bees came from the vibration of the wings, up to 200 times per second, and if the wings stopped vibrating, the sound would also stop.

The little girl told the teacher about this question, but the teacher only believed what the book said. Not resigned, she began to do her own experiments to explore the true mystery of bee sounds. She glued the bee's wings to the board, but the bee was still buzzing.

In this way, after many observations and thoughts, she carefully searched with a magnifying glass, and finally found two black dots smaller than rapeseed on the roots of the bee's wings. If you pierce the small black dot with a pin, the bee will stop making sounds. From this, she came to the conclusion that bees do not make sounds by wing vibration, and wrote about **, which won the Gao Shiqi Science Popularization Special Award.

The sound of their wings.

The physics teacher mentioned that it is not only the wings, but also the small black dots under the wings.

No, it's because the bees have black spots on them.

The buzzing sound made by the bee when flying is a direct result of the flapping of the wings, which is the sound that causes the air to vibrate due to the flapping of the wings. And the frequency of the bees flapping their wings is very high, reaching 300-400 times per second, which is 300-400Hz, so the buzzing is obvious. In addition, when the hive is attacked, the bee will increase the frequency of the wing vibration to show anger, and the buzzing will be louder.

This is also the principle of the sound made by insects such as mosquitoes and flies. Flies flapping their wings about 200 times per second, that is, 200Hz; Butterflies only flapp their wings 5 to 6 times per second, so there is no sound when flying.

This sound is mainly produced by the friction between the wings and the air during the flapping process.

If inside you take a fan, give.

You can also hear a voice, although it is different from the sound of a bee, but the principle is similar.

And mosquitoes are similar, when we sleep, as long as the mosquito flies to our ears, we can hear the sound of its wings. But the sound of mosquitoes is the most annoying.

Bees can make sounds by rubbing their wing muscles, and if their wings are folded, they make a buzzing sound, similar to the flying version.

The pronunciation of time is different. The bees' vocal communication prior to the grouping right is the most typical.

The bee's vocalization is not entirely due to the vibration of the wings, but also plays an important role in the two black dots at the base of the bee's wings, which are smaller than rapeseed, and when the bees chirp, the small black dots agitate up and down. This is the reason why bees make sounds.

There is no clear answer to the question of the vocalization of bees and whether bees have a vocal organ.

There are two ways to say that the outside world is DAO: one is that in the process of agitation, the wings resonate with the surrounding air due to the friction with the air, so they will produce sound. The second is that the bee's vocalization is not due to the vibration of the wings, but the eardrum on the wings, that is, a small black dot, and the vibration of the small black dot also causes the bees to chirp.

There is no definitive answer as to how the bees buzz sound, but there are two theories in the scientific community.

The first theory is that the buzzing sound of the bee comes from the vibration of the wings, and when it is flying, it quickly stirs the wings to make the air vibrate, and it makes a buzzing sound.

The second theory is that the wings of bees assist in the amplification of sound, but they are not articulatory organs. After experiments, after cutting off the wings of bees, it was found that bees can still make sounds. Although it is not yet clear what the organ of the bee is to make sounds, one thing is for sure, bees do not make sounds by vibrating their wings.

The bees returning from collecting honey are full of loads, they are tired and unable to fly, the buzzing sound is low and dull, and the bees that are flying out to collect honey are light without honey, flapping their wings and flying with high frequency and fast buzzing sound.

The first theory is that bees quickly stir their wings when they are flying.

The air vibrates, so that the inside will make a buzzing sound. The second theory is that the wings of bees assist in the amplification of sounds, but they are not articulatory organs, and after experiments, it was found that bees can still make sounds after cutting off their wings. The third theory is that the back plate and web of the bee are vibrated together.

So the buzzing of bees is still inconclusive.

Not yet.

Determine what the bees rely on.

Because the bee bai does not have a vocal organ, and experiments have shown that the bee zhi still has a buzz after the wings are clipped

Buzz, so bees don't make sounds because of the vibration of their wings.

There was an experiment with elementary school students who thought that bees made vocalizations because of black spots on their bodies, but later experiments showed that bees without black spots could still make sounds, so this conclusion was also wrong.

The sound produced by the wings of a bee vibrating at high speed.

There is a copy

It is said that the back plate and web plate of the bee make sound together through vibration.

There is also a theory that a primary school student discovered through experiments that bees without wings can also make sounds, but there are two small black dots on the wings of bees, and if these two small black dots are punctured, the bees will have no sound.

There is no conclusion on who of these two statements is right for the time being.

The buzzing of bees is the sound produced by the eardrum under the bow.

Because it will hum, it will hum.

It should be the high-frequency incitement of the wings in the air with a vibrating sound.

Of course, the wings came out.

That's not what I'm looking for
