Conch is a relatively common creature at the seaside.When we pick up conch shells and put them close to our ears, we hear a sound, and sometimes the sound is very loud.In fact, the conch ring is caused by the resonance phenomenon.There is air inside the conch, and when there is a sound outside, it will form a resonance phenomenon with the air inside the conch.At this time, when we put the conch next to the ear, we can hear a louder sound.
Of course, if the outside world can be kept absolutely quiet, that is, if there is no faint sound, then it cannot resonate with the air inside the conch. At this time, even if we put the conch close to our ears, we will not hear the sound.However, the outside world can not maintain absolute silence, so when we go to listen to conch, generally there will be sound.
As mentioned above, when we put the conch close to our ears, we will hear a relatively loud 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 low, it can be gathered and enhanced inside the conch.So, when we put the conch close to our ears, we can hear the "voice of the sea".
