Why does the conch sound when it is placed in the ear, and why does the conch sound in the ear?

The air in the conch cavity is an elastomer like a spring, and when the external sound wave is transmitted to the cavity, it is transmitted from the cavity to the bottom of the cavity, and then from the bottom of the cavity to the cavity mouth. If the frequency of the sound wave is equal to the natural frequency of the air in the cavity, then the air in the cavity resonates with the sound wave and produces a louder sound. The inside of the shell is curved and filled with air, so when you are in a noisy place, these noisy sounds make the air in the shell vibrate, so if you put the conch in your ear, you will hear the sound of the tide.

When you are in a particularly quiet room, there is very little sound around you, and the volume is so small that you can't make the air in the shell vibrate, and there are noises of various frequencies all around us, which are very light and not usually noticed. When the cavity is placed close to the ear, the air inside the cavity resonates with certain frequencies of noise, resulting in a more pronounced humming sound. Romantic sayings.

The scientific explanation is that the structure of the shell allows it to rely on resonance to amplify certain frequencies of sound in the environment, such as the sound of human blood flowing. So put the shell to your ear, and most of what you hear is the sound of blood boiling from the depths of your heart.

That's the echo of the blood flow in your body, it's amazing, right?

What the conch hears in your ear is not the sound of the sea, but "white noise", and the conch itself has no sound. Just because of the shape of the conch that forms a resonance cavity. "White noise" is a low-frequency and uniform sound signal that is usually ignored by the human ear.

The conch is a mollusk gastropod, and the mollusk phylum macroswims. There are more than 70,000 species of shellfish in the world, and the marine species can be commonly known as sea snails.

The conch shell edge is slightly square in outline, large and thick, the shell is about 10 cm high, and the spiral layer is 6 grades. It is rich in protein, vitamins and essential amino acids and trace elements, and is a typical natural animal food with high protein, low fat and high calcium.

There is the sound of the sea in the conch, which is caused by the phenomenon of resonance.

The conch has a small opening and a lot of space for internal curves, which is filled with air.

The sound from the outside world resonates with the air inside the conch, causing the inside of the conch to have sound.

When the conch is near the sea, the sound of the sea resonates with the air inside the conch, so they have the sound of the sea.

If the conch leaves the beach for a long time, the sound in it is no longer the sound of the sea, but something else.

1. Why does the conch ringThe conch is a relatively common creature on the seaside.

When we pick up conches and bring them close to our ears, we hear sounds, and sometimes they are very loud.

In fact, the conch ringing is caused by the phenomenon of resonance.

The conch has air inside, and when there is a noise from the outside world, it will resonate with the air inside the conch.

At this time, when we put the conch next to our ears, we can hear a louder sound.

Of course, if the outside world can be absolutely quiet, that is, there is no faint sound, then it will not be able to resonate with the air inside the conch, and even if we put the conch close to our ears, we will not hear the sound.

However, it is impossible to be absolutely silent from the outside world, so when we go to listen to the conch, there is generally a sound.

2. Why does the conch have the sound of the sea has been introduced above, when we put the conch close to the ear, we will hear a louder sound inside.

When the conch is near the sea, the sound produced by the sea can resonate with the air inside the conch, so they have the sound of the sea.

Even if the sound is relatively small, it can be gathered and enhanced inside the conch.

So, when we put the conch close to our ears, we can hear the "sound of the sea".
