Conch is a creature that can often be seen in daily life, and it is quite common at the seaside.When people go to the seaside to play, it is easy to find a lot of conch.If you put your ears close to the conch at the seaside, there will be a relatively loud sound inside, that is, the so-called "sound of the sea".This phenomenon is relatively common, many people regard this sound as the sound of the sea, and think that this is because the conch lives in the sea.In fact, the generation of this sound is based on physics and is the result of sound resonance.When there is a sound coming from the seaside, it will drive the air inside the conch to vibrate, and then you can hear the sound of the sea.
However, if the conch is not at the seaside, when you put the conch to your ear at this time, you will not hear the sound of the sea, because the sound resonating with the air inside the conch is not the sound of the seaside.
If you put the conch close to your ear at the seaside, you can hear the sound similar to the sea. This phenomenon has a physical basis.In fact, this principle is the same as that of some musical instruments, such as pan flute, organ and so on.
When the outside of the shell makes a sound, it will drive the air inside the shell to vibrate.Even if the outside sound is relatively small, the outside air can still drive the vibration of the air inside the conch.One of the important characteristics of conch is that it can gather and amplify this sound.That is to say, even if it is only a weak sound, it will be amplified and enhanced in the conch.At this time, the conch will send out the sound of the sea.
